Every home with plumbing has a supply of cold water coming into the building and a main drain to handle sewage leaving the building. The incoming cold water supply feeds both the cold water faucets and taps, as well as the water heater.
Hot and cold water supply lines extend to most fixtures in your house, with a series of smaller drain pipes leading from sinks, toilets, showers and tubs to the larger main drain. In general, problems with the water supply side of residential plumbing are usually about leaks of some kind. Drain issues are usually about blockages. Kitchen sinks and toilets are the most likely location for blockages, but all drain pipes can become blocked.
Although major plumbing leaks don’t happen often, when they do, they can cause serious damage in a very short time. That is why every homeowner needs to know where the main water supply shutoff valve is and how to use it. Find the main water supply pipe that enters your house, typically located on a basement wall. If your house is in a subdivision, water supply lines usually enter the wall closest to the road. The first valve present on this pipe is the main shutoff. Rotate the handle clockwise until it stops to shut off the flow of water.
For most major leaks you will need a professional plumber to fix the issue, but being able to turn off the water supply beforehand can help to avoid additional damage. It is recommended that everyone in your household know how to shut off the main water supply valve in case of a sudden leak.
With a high concentration of plumbing fixtures, bathrooms are often the source of plumbing issues in your home. Most household toilets, sinks, showers and bath tubs are used frequently so occasional issues are not uncommon. Understanding how these plumbing fixtures work is the first step in understanding what is causing the problem.
Whenever the flush handle of a toilet is pushed down, it opens a flush valve in the bottom of the water tank. This allows water to rush down into the toilet bowl, carrying waste into a large drain pipe hidden in the floor. As the water level in the tank drops during a flush, it opens a fill valve to refill the tank to a preset water level, ready for the next flush. The water that remains in a toilet bowl after flushing seals out sewer gases and prevents them from entering your home.
Villa Park PlumberPotential trouble spots for a toilet include the water supply connection to the water tank, the gasket that seals the toilet to the floor drain, the gasket that seals the tank to the bowl, and the flush valve and fill valve inside the tank.
Not all new toilets flush as well as they should, and that’s why you should consult independent testing to choose an effective model. An organization called MaP publishes performance results from hundreds of toilets available around the world. Click here for free recommendations on finding a new toilet that flushes cleanly.
These are usually replaced as part of a bathroom renovation or vanity cabinet replacement. Bathroom sinks can be a molded part of the vanity cabinet top, they can be under-mounted to the bottom face of the countertop or they can be mounted on top of the vanity top resting in a hole cut on site during installation. You’ll need to get your plumber involved early on in your bathroom renovations to determine if pipe and drain locations need to be changed.
Most tubs offer the opportunity to take either a bath or shower and feature a combination faucet that includes taps, a tub spout and a shower head. Access to the hidden valve assembly is sometimes found through the wall on the other side of the tub.
Use caulking solvent and a scraper to remove all old caulking, then apply masking tape along each side of the joint, 3mm or 4mm (1/8” to 3/16”) from the centre line. Apply a bead of caulking between the pieces of tape, then smooth the caulking with your index finger wetted with a 50/50 mixture of water and dishwashing liquid. Peel the tape off immediately and leave the caulking to dry for 24 hours before using the shower.
The kitchen is the centre of most homes, and plumbing has a lot to do with the reason why. Preparing and serving food and cleaning up afterwards depends largely on plumbing. Kitchens also have the greatest number of water-related technologies at work. In addition to faucets and drains, you might also have a dishwasher, a fridge with water dispenser, and maybe even laundry equipment in the kitchen.
Potential trouble spots for a kitchen sink and faucet include dripping faucet (most common), leaks where the sink meets the counter top, leaking drain pipes, leaking connection between the water supply pipes and the faucet, a clogged drain, or a malfunctioning garbage disposal or hot water dispenser.
Most faucets and taps made until the 1970s used a small disk of rubber called a “washer” to stop the flow of water when the hot or cold tap handle was shut off. The faucet mechanism closes down and squeezes against the washer, sealing off the space for water to flow through. Eventually the washer gets old, brittle and cracked, allowing a small flow of water even when the handle is tightened down fully. Inexpensive replacement washers are still available in any hardware store to stop dripping, even for very old faucets. Most modern faucets don’t have washers but use a replaceable valve cartridge instead. When these leak, the only practical solution is to replace the cartridge. Both washer and cartridge replacement is something that a handy homeowner could complete themselves.
The lack of an air vent is the leading cause of a sink drain that makes gurgling sounds as the water goes down. Adding an air admittance valve to the drain pipe may solves the problem. Not every jurisdiction allows air admittance valves, but they can work well and are relatively easy to install. If you are experiencing a gurgling drain, call a licensed plumber to see if an air admittance valve is an option.
All dishwashers have a connection to the drain (usually under the kitchen sink), but most only have an inlet for a hot water supply. Since dishwashers don’t have cold or warm cycles, a hot water feed is all that’s needed. This hot water feed usually taps into the supply pipe near the kitchen faucet. The only exception to this are high-end dishwashers with internal water heating capabilities. These might have a cold-only connection or they might heat the already-hot water to a higher temperature.
If your dishwasher fails to get your dishes, glasses and cutlery as clean is you’d like, and it appears to be running well in other ways, try running your kitchen faucet until the water is hot before each dish washer load. These days dishwashers use so little water that they might not actually get to the completely hot water from the hot water supply pipe. Running the kitchen hot water tap until the water gets hot can improve dishwashing results by eliminating the residual cold.
Depending on how much drinking water you take from your fridge, the filter may need to be changed every six months to a year. Most fridges have a warning light to alert you when filter needs changing, but you might not get around to this right away. Be sure to check the manufactures recommended replacement cycle and mark the installation date on the filter label before installation so you know at a glance how long it’s been in place.
Leone Plumbing Residential Plumbing GuideMost households rely on residential plumbing for day-to-day chores such as cleaning the toilet, washing dishes, laundry, bathing, and more. A few hours with no running water or clogged drains can be a serious problem for a household. Getting caught off guard with plumbing issues will cause you so much stress. This residential plumbing guide will provide you with basic tips to resolve or prevent some plumbing problems in your home.
Do a routinary inspection of exposed pipes for signs of wear and tear that causes leaking. You can rub a compound stick for tiny leaks in pipes. A compound stick is available at most hardware stores.
Avoid planting trees near the sewer lines because the roots can be a source of damage. We also suggest periodically snake the lines. If the roots have seriously damaged your sewer lines, let an experienced master plumber fix the problem. Do not fix it on your own as you may also damage other plumbing systems and will lead to civil lawsuits.
Remember that clogs of today are the result of yesterday’s mistake. Keep debris from drains and be watchful of what goes down. Educate your household with proper plumbing maintenance. Set up house rules like what to flush and what not flush on the toilet.
