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.
Potential 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.
