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:
Your water heater is one of the most important parts of your home – it’s used for everything from showering to doing laundry to washing dishes and more, which is why it’s important to maintain it. Learning how to do simple maintenance on your water heater can extend its lifespan and keep it running smoothly all year long. Here, our water heater experts share some tips:
Checking the Pressure Valve
Whether you have an electric water heater or a gas-powered water heater, you’ll find a safety devices called a temperature and pressure relief valve. It’s important to make sure this valve is operating correctly because if it’s not, it can mean an explosion.
First, turn off the power to the water heater and shut off the cold-water inlet. Next position a bucket of water underneath the valve and pull up the lever. (You should hear a rush of air and see some water vapor.) If water continues to flow out of the valve, drain the tank partway, unscrew the old valve, and replace it with a new one.
Replacing the Anode Rod
A water heater’s anode rod protects the exposed steel of the water heater when the tank is filled through a method called electrolysis. Because the rod protects from rust, it can become coated with calcium carbonate and should be replaced.
Start by connecting a garden hose to the tank’s drain valve and open the pressure relief valve and the drain valve. Let a few gallons of water drain out and close the drain valve. Next, look for the hex head of your anode rod on top of the heater or under the top plate. Once you locate it, fit a 1 1/16-inch socket onto the head and unscrew the rod. Examine it – if it’s less than 1/2 inch thick or covered in calcium carbonate, buy a new one, wrap its threads with Teflon tape, and replace the rod.
Flushing the Tank
As your water heater gets older, sediment will begin to settle in the tank and not only reduce the heater’s efficiency, but clog the lines. This is why you should flush your tank on a regular basis.
First, start by turning off the power to your water heater and shut off the cold-water inlet. Connect a garden hose to the tank’s drain valve and make sure the other end of the hose is in an area that won’t be negatively affected by hot water. Open the pressure relief valve, then open the drain valve. Let the tank drain completely and close the relief valve and drain valve. Turn the cold-water inlet back on and open up all hot water spigots in your home to refill.
If you’re uncomfortable working on your water heater, don’t hesitate to call our water heater experts! We can have your heater maintenanced in no time!
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…”
Unfortunately, heating systems only last so long and there comes a time when you’ll need to replace yours. If your system falls under one of these “if”s, it may be time to call our heating installation experts:
If it’s old and inefficient
Take a moment to determine how old your heating system is. If it’s between 15 and 20 years old, our Oliver heating service experts recommend replacing it. Over time, the efficiency of a system deteriorates and you could actually be paying more money than you need to to heat your home.
If you have humidity problems
Have you noticed that your home’s air is too humid in the summer or too dry in the winter? If so, the problem could be an inadequate heating system. Schedule an appointment with one of our experts. We can tell you whether you should replace your system or not.
If it needs frequent repairs
A heating system that is constantly in need of repairs should be a red flag to homeowners. Constant repairs not only cost you money, but they often mean that your system isn’t doing the best job of heating your home and you’re better off upgrading to a newer one.
If your heating bills are rising
If the price of your heating has stayed relatively the same but your bills have gone up, your heating system is using more energy than it should be. Switch to a more energy efficient system and you’ll be able to save your money.
If some rooms are cold and others are hot
Have you ever walked from one room in your home to another and wondered why the second room is so different in temperature? This is a sign that your heating system isn’t operating at its best and can’t properly distribute warm air to your home’s rooms.
If your heating system is making weird noises
One of the most obvious signs of a heating system that’s on it’s way to failure is one that makes weird noises like pops, rattles, squeals, and more. If you hear weird noises coming from your system, call our heating installation experts today.
If any of these scenarios apply to your heating system, you’re most likely better off upgrading it to a newer model. At Oliver, we carry a wide array of systems and can help you pick the right one to heat your home efficiently and help you save money on your bills.
It’s hot outside, and if you’ve unfortunately experienced a broken or overheated air conditioner, you probably don’t want to go the rest of the summer without one. At our HVAC company, air conditioner installation is one of our specialties, but before you decide on a new unit, there are a few things we think you should think about:
The Right Contractor Is Key
There are a lot of HVAC contractors out there and before you schedule your air conditioner installation, make sure you know the company well. Sometimes homeowners who are unfamiliar with the world of HVAC feel pressure to make decisions about their new system. A reputable, trustworthy contractor will answer your questions thoroughly, provide examples of high quality workmanship, and employ technicians and installers you feel comfortable with in your home. We know an air conditioner is a big investment, and finding the right contractor is key. Do some research on each company and find out how long they’ve been in business, if they’re focused on customer satisfaction, and if they have the proper licensing (like us!).
You Don’t Need to Go Big
While it may seem like a larger air conditioner will do a better job of cooling your home, that’s not always the case. Today, air conditioners have been getting smaller while still being able to give you the amount of energy you need. If a contractor suggests a larger, more expensive air conditioner for your home, be wary and get several other opinions before you agree. Also keep in mind that a larger air conditioner will cost more to run and put more stress on your equipment than a smaller one.
As we said, an air conditioner installation is a big investment, which means you should talk to more than one HVAC contractor before making a decision. Each contractor may offer you different prices, warranties, labor costs, and more, so make sure you get written estimates from each one and don’t just choose the one who will do the job for the least amount of money. Also make sure you choose a contractor you feel comfortable with and who isn’t afraid to answer any questions you may have.
Don’t Forget About SEER
Today, each air conditioner has a SEER (or Seasonal Energy Efficiency Ratio) rating number that will tell you how efficient an air conditioner is. The higher the SEER number, the better the air conditioner. We recommend not making a decision on an air conditioner until you’ve talked to an expert about what SEER number is right for your lifestyle. For example, if you’re planning on selling your home in a few years, you may only need a mid-rated unit instead of a high-rated one.
For any other questions you may have (and for the best air conditioner installation experts in the area), give us a call today.
