When you trip a circuit breaker or your heating system fails, you can tell. Plumbing, however, isn’t as easy to read. Because your sewage system is underground, it’s not always obvious when there’s a problem. Here, our plumbing experts share five signs to look for that may indicate a sewage leak:
At Oliver, we’re proud to offer the best products and workmanship to homeowners and commercial building owners. Since 1971, we’ve focused on customer satisfaction and have built up a wonderful customer base around the area – we’ve even been named Contractor of the Year! Here are some of the most recent HVAC reviews we’ve received from our customers about our company:
Commercial buildings often have much larger plumbing systems than residential homes, which makes them more susceptible to plumbing problems. In this article, our commercial plumbing experts explain some of the most common problems a commercial building may experience and how to prevent them:
At Oliver, we know it can be a little intimidating when it’s time to choose a plumbing company, so we asked our plumbing experts what they’d recommend doing before deciding. Here are the questions they would ask:
Are you considering selling your home? Don’t let little problems get in your way. There are several things you can do to make sure that your home is appealing to visitors and potential buyers. Here are some suggestions from our HVAC and plumbing service experts:
Updating your entryway
One of the first things a visitor will notice about your home is your entryway. Liven it up by giving your front door a fresh coat of paint (or even replacing it, if it’s outdated) and hanging or planting some colorful flowers. You can also add a welcome mat and a door wreath for an added warm welcome.
Replacing your HVAC system
If your HVAC system is old and inefficient, it won’t be much of a selling point to a potential buyer. Talk to the experts at Oliver about replacing your system; we carry an array of gas, electric, and oil furnaces, air conditioners, heat pumps, and more. We’ll help you figure out which system is the best fit for your needs and your budget.
Whether it’s your shower head, kitchen sink, bathroom faucet, or outdoor spigot, no one likes a leaky fixture. You’ll give the impression that your home is old and not taken care of, which can lower your chances of selling. If you’re unsure how to fix the leak yourself, give us a call. Even slow leaks can lead to several gallons of water lost every week, so limit your water waste and make your home buyer-ready.
Adding a deck
When it comes to home improvement projects that have a successful payback, a deck is definitely one of them. A deck increases your living space and allows for outdoor entertainment. Just by building a 16×20 ft. pressure-treated wood deck with a simple layout, you can look forward to an up to 90% payback when you go to sell your home. Our home remodeling team can help you design and build your very own deck – just call us and set up an appointment!
If you don’t have the money to replace or refinish your cabinets, a simple hardware update can spruce them up and give them a whole new look. The same goes for other hardware like doorknobs and drawer pulls. Choose pieces that give your home a modern, yet elegant look.
Revising your landscaping
Before visitors notice your entryway, they’ll notice your landscaping – which means they’ll notice if you haven’t updated it in years. Take the time to trim up your trees and shrubs, replace dead plants, and add some new pieces to complement the size and shape of your home. You can even add some in-season flowers for a colorful pop.
Owning a home means there are some projects you’ll probably take on by yourself, such as landscaping, painting, and decorating. When it comes to plumbing, however, it may be hard to tell whether your problem is something you can fix or something you should call the pros for. We’re here to help:
As a homeowner, you’re probably going to experience a minor plumbing problem at some point or another, which is why it’s important to have an emergency plumbing kit handy. Here are some great things that can help you fix common situations:
Summer is over and autumn is quickly approaching, but is your home ready for the cooler temperatures? At our Oliver, we’ve put together nine ways to get your home ready for the fall (including calling our experts!):
Check for Drafts
Check your windows and doors for drafts so that your home doesn’t take on cold air when you don’t want it to. You can check them by lighting a candle and holding it near the area. If it flickers, there’s a draft. You’ll want to replace the weather stripping and/or caulking to get a nice, strong seal before the cold sets in.
Prep Your Washer & Dryer
All of those loads of summer laundry mean your washing machine and dryer have gotten a lot of use. Be sure to check your washing machine hose – one that’s too worn can burst and spill gallons of water very quickly. Also make sure that lint hasn’t built up in your dryer – too much lint can catch fire from the dryer’s heat.
Replace Your HVAC Filter
Summer comes with a lot of dirt, dust, pollen, grass, and other airborne contaminants. Start fall with a fresh, clean HVAC filter and you’ll be breathing easy as the temperatures get cooler.
Seal Your Walkway/Patio
If you have a paver walkway or a paver patio, take some time to seal it before the ice, snow, and cold temperatures hit. You’ll protect it all winter long and will love the way it looks come springtime.
Schedule a Furnace Check-Up
Make an appointment with one of our heating service experts to do a thorough check of your heater. We’ll make sure it’s working properly and ready to use once the temperature drops so you don’t experience any unwanted and inconvenient problems.
Fertilize Your Lawn
Grass roots will continue to grow until the ground temperature gets down to 40 degrees, so feed your grass a fresh helping of fertilizer to keep it growing strong through the fall and ready for winter.
Install Outdoor Lights
As it gets cooler, the days get shorter and there are fewer hours of sunlight, so why not install a few outdoor lights on your garage or ones that lead to your front door? You’ll light the way not only for yourself, but for your guests, too.
Test Your Detectors
Put fresh batteries in your smoke detector and carbon monoxide detector and test them to make sure that they are working properly. This is a good thing to do every few months.
Insulate Your Pipes
When colder temperatures hit, your plumbing pipes could freeze and burst, causing big plumbing problems. Our plumbing experts can make sure your pipes are prepared for the fall and winter – just give us a call.
Say Hello to a New Kind of Toilet
While many other household appliances have evolved, the toilet has stayed relatively the same. Until now. A company called Loowatt has developed a water-free toilet that could make a big impact. Here, our plumbing experts share a portion of a Quartz article written by Lina Zeldovich about the new technology:
“Eleonore Rartjarasoaniony – a 47-year-old mother, daughter and small-shop owner in Madagascar’s capital Antananarivo – stands in the middle of her yard, watching two young men in colourful overalls and rubber boots service her new waterless Loowatt toilet, which replaced her pit latrine a few months ago. At her feet, two lean, long-legged chickens, flocked by a bunch of fluffy chicks, peck at anything remotely resembling food, including my shoes.
Inside a wooden shack behind her, Rartjarasoaniony’s elderly mother greets customers through a small window that overlooks the narrow, unpaved neighbourhood street. That’s Rartjarasoaniony’s shop, in which she sells a bit of everything – kitchen sponges, eggs laid by her hens and freshly brewed coffee, which she hands out to customers in small metal cups, rinsed in a bucket of water from a communal pump.
As she describes her new toilet in the soft Malagasy language – and Loowatt’s manager Anselme Andriamahavita translates – I discern the word tsara in the string of unfamiliar sounds. By now I’ve learned that tsara means ‘well’, as in wellbeing and healthy. Rartjarasoaniony switched to the new toilet because it’s cleaner and safer than her outhouse. “My family of four uses it, and so do my three tenants who rent the next house over – it’s included in the rent,” she says. “Even my son can use it,” she adds, echoing worries of all Malagasy mothers, terrified that their young children may one day fall into a pit and literally drown in shit.
Like most Madagascan residents, Rartjarasoaniony and her tenants don’t have modern sanitation systems in their homes, which are built with bricks hand-made from red Madagascan mud. While cellphones are ubiquitous in Antananarivo, flush toilets are not. Most people use “Malagasy toilets,” meaning outhouses. Out in the country, some villagers don’t even have those – when nature calls, they head to the bushes or into the fields. The more sophisticated Malagasies who do own latrines call it “going au natural.”
But latrines aren’t a hygienic solution either, and not only because they smell and are hard to keep clean. Madagascar has so much groundwater that many Antananarivo residents grow rice in their yards. When torrential rains hit, everything floods. The waste from latrines rises and floats into the yards, houses, shops and streets. The threat is very real. In a neighbour’s latrine across the street, the sordid grey goo almost reaches the pit’s surface, a clear menace come the next storm. “When we used the pit latrine before, and it rained, sometimes the water would come out,” Rartjarasoaniony tells me. “And we were afraid of getting sick because of the filth.”
Lack of toilets is not a problem unique to Madagascar. The World Health Organization (WHO) estimates that 2.4 billion people lack access to basic toilet facilities, and nearly 1 billion can’t even do their business in private, practicing so-called “open defecation,” resorting to fields, street gutters or creeks. Many countries, primarily in sub-Saharan Africa and South Asia, face similar sanitation challenges, says Francis de los Reyes at North Carolina State University, who designs sanitation management solutions for developing counties.
In many places building a flushing toilet system, as we know it, is nearly impossible. Some places simply don’t have enough water. Some have too much, which complicates water treatment processes because of floods and overflows. Others don’t have the means to build the water-based infrastructure. That’s why Loowatt, a London-based startup, came up with a radically different flushing solution – one that doesn’t use water at all.
In Loowatt’s waterless flush design, the waste is sealed into a biodegradable bag underneath the toilet with not a drop of water being spilled. Once full, the bag is replaced by a service team, and the waste is brought (yes, hand-delivered) to Loowatt’s pilot waste-processing facility, where it’s converted to fertilizer and biogas.
This very manual setup sounds very archaic compared to the slick and convenient arrangements of the Western world. But sanitation experts think that in the era of climate change, when droughts and floods are becoming increasingly common, the West may have something to learn from the little waterless loos piloted in penniless Madagascan neighborhoods. With the world’s population ever-increasing, places that historically relied on water for sanitation may have to reconsider how they flush.
A whole new loo
Loowatt’s London-based founder and CEO Virginia Gardiner never thought she’d end up designing 21st-century toilets. When she graduated from Stanford University in 1999 with a bachelor’s degree in comparative literature, she couldn’t have been further removed from the engineering challenges of processing human waste. But then she went to work as a reporter for an architecture and design magazine, Dwell, covering industry events. “I was the youngest on the edit team. Nobody else wanted to go to the kitchen and bath industry shows, so I did,” she recalls. One of the things that struck her was that architectural concepts evolved constantly, except for toilets, which seemed to remain the same for ever.
“The first article I wrote for the magazine was about toilets – about the fact that they don’t change,” she says. She came to see the overall ‘bath culture’ as wasteful and decided toilets were due for an upgrade.
When Gardiner did her Master’s thesis at the Royal College of Art in London, she chose to focus it on a waterless toilet system. In 2010, she founded Loowatt and ran a money-raising campaign based around turning “shit” into a commodity. When in 2011 the Bill & Melinda Gates Foundation issued the Reinvent the Toilet Challenge to devise sustainable sanitation technologies to handle the number one (and, well, the number two) of humankind’s basic necessities, the requirements matched Gardiner’s waterless design. She applied for the grant and got it.
More funding followed, including from Innovate UK, the GSMA Mobile for Development Utilities Programme and, more recently, a RELX Group Environmental Challenge award. Serendipitously, a Canadian expat living in Madagascar learned about Gardiner’s project from her online video and became Loowatt’s first investor. That was the reason Loowatt launched its first single-toilet pilot and a small waste-processing facility in an impoverished Antananarivo neighbourhood.
The project killed two birds with one stone – giving people a toilet, and converting their waste to biogas, generating enough electricity to charge cellphones. When that proof of concept worked, Loowatt scaled up to its current size – 100 toilets serving about 800 customers.
In their basic appearance, Loowatt toilets don’t look much different from our Western johns, with their plastic seats and flushing handles, which come in the form of a pedal or a rope you pull. But instead of releasing a swirl of water into the basin, this move activates the white biodegradable film that envelopes and seals the waste, pushing it into a collector underneath the toilet, all odour-free. Loowatt’s service team replaces the biodegradable bag once a week, or more often if it fills up sooner.
Equipped with a small pushcart and collection bins, a two-person team conducts daily walks through the neighbourhood, gathering waste bags and doing repairs. The residents can also request service by text message when the bag fills up or if something breaks.
The Loowatt setup isn’t free – residents pay about £12 as a deposit for a toilet (which remains Loowatt’s property) and about £3 a month for service. For Madagascar, where some families exist on £1 a day, this isn’t cheap. But Rartjarasoaniony tells me she finds it acceptable. Maintaining a latrine costs more. “We have to empty it every six months, and it is really expensive,” she explains, not to mention the unsightly mess it creates. The manual process is done by ‘informal emptiers’ – usually men who show up with buckets to chug the goo into containers, dropping splotches of repugnant gunk around the yard for her egg-laying hens to peck at.
Standing behind Loowatt’s technician Edonal Razanadrakoto, I watch him tinker with Rartjarasoaniony’s toilet flushing mechanism. “In the older version of the toilet you had to push a pedal to make the bag seal the waste,” he explains, pointing at the plastic cogs and wheels. That mechanism ultimately relied on an internal rope, which often jammed and tore, so Loowatt switched to a sturdier, hand-pulled device, and now the toilets have to be upgraded. While Razanadrakoto changes the part, his coworker stashes the waste bag from underneath the toilet into a white bin on his pushcart and taps on the phone to update Loowatt’s online monitoring system: bag removed.
As we leave, Andriamahavita, the Loowatt manager, says that another neighbour also wants to talk. “She was about to go to work, but heard we were in the neighbourhood, so she waited,” he explains.
Sporting a white shirt and long braided hair, 43-year-old Gloria Razafindeamiza greets us in front of her house, next to her Loowatt toilet cabin, which is woven from recycled plastic. Only a few steps away on the ground a pressure cooker atop a charcoal burner simmers vary – rice, which locals eat three times a day. As Razafindeamiza explains her ordeals with the Malagasy way of using the toilet, a range of expressions crosses her face, from embarrassment to disgust. She works for the Ministry of Health, Andriamahavita explains, and really hates the unsanitary side of it all. A renter who moved here recently, she had to share an outhouse with several neighbours, some of whom didn’t clean up after themselves, leaving it unusable.
“With this toilet I feel safe and secure.”
It was also too far from her house, which made things difficult. “If diarrhea comes up at night, I’m afraid to go there,” she says. “Sometimes you would go there and it would be really dirty and you’d have to clean it before you could use it.” Electricity isn’t always available in Antananarivo either, so imagine doing all that in the dark. “With this toilet I feel safe and secure,” she adds.
As we leave her yard, I steal a glance at Razafindeamiza’s living room through the window, which, like many other houses here, doesn’t have glass in the panes. The room looks nice, with teak furniture, a TV and pictures of Santa Claus and Dora the Explorer on the walls. But at the gates, we hop over a ditch that carries wastewater out of the house and into the gutters on the street. The ditch is full of a stagnant greyish fluid that stinks of rotten food and probably of faeces too. By now I am so immune to these smells that I can’t tell if it’s just muddy water or a recent overflow from a latrine. As de los Reyes, who studies faecal sludge management, once said: “In the developing world, people are surrounded by shit, often unbeknownst to them.”
Later, as Andriamahavita is driving us from Loowatt’s pilot neighbourhood to the main office, I can’t help but ask: “Gloria works for the Ministry of Health, and her house looks rather nice, so why can’t she afford a home with a better toilet?”
“A government job doesn’t necessarily pay a lot of money,” Andriamahavita explains, but the biggest problem is the infrastructure. “We don’t really have a sewage system like in the Occident.” Middle-class Malagasies can afford certain life perks, like a TV, a stereo system, a smartphone, even a second-hard car. But a flush toilet isn’t something an individual’s money can buy.
A flush toilet needs a sophisticated set of underground pipes linking it to a facility that can digest its output – a sewage plant that cleans the water, releasing it back into the rivers and oceans, and re-processes the so-called biosolids into fertiliser safe to put onto fields…
Does Loowatt’s approach have the potential to change how the world processes its waste? The company is working on introducing the concept to other countries – in Africa, Asia and Europe. In the UK, for example, Loowatt toilets are already being used at festivals and outdoor events, generating good revenue…”
Our HVAC Service Experts Explain
Have you ever wondered what the differences are between hard water and soft water? Which is better for your health? Which you should use in your home? Our HVAC service experts are here to answer some of the most popular questions about hard and soft water:
What’s in the water?
Hard water contains dissolved minerals like calcium and magnesium that are picked up by the water when it runs through underground pipes. Soft water only contains sodium.
Can I drink hard water?
Yes. Hard water is safe to drink, and can even be considered a dietary supplement for magnesium and calcium.
Why do people soften their water?
Because hard water contains minerals, the minerals can build up on the surfaces of faucets, in boilers, water heaters, and in household appliances. This build-up (also called scale) can compromise the efficiency of these things. People also soften their water because the minerals in hard water interact with cleaning products and don’t clean as much. Soft water lathers better with soap and detergent.
How does the softening process work?
Water softeners are filled with small polystyrene beads that are negatively charged, but contain traces of sodium. Since calcium and magnesium both carry positive charges, they cling to the beads as the water passes through the tank and sodium ions are released into the water (which is why soft water has a sodium content). The water is then pumped through your home’s faucets.
What’s the difference between temporary hardness and permanent hardness?
When water is considered temporarily hard, it’s because it contains dissolved bits of calcium and magnesium. These can be removed by boiling the water or by treating it with lime. Permanently hard water, on the other hand, has calcium and magnesium sulfates that can’t be removed with heat and must be treated with a water softener in order to be removed.
Water is classified (in the U.S.) by its hardness in “parts per million” or ppm.
Soft water: 0-60 ppm
Moderately hard water: 61-120 ppm
Hard water: 121-180 ppm
Very hard water: more than 181 ppm
