How to Vent a Bathroom Plumbing
If you are wondering how to properly vent your bathroom plumbing, here are some tips. Before you start, you need to know where to install the vent pipe. The right place is where water can escape without draining into the toilet. You should install it six inches above the spill line, the level where water overflows from the rim of the sink. Otherwise, you’ll end up with a pipe that’s too short and won’t work properly. how to vent a bathroom plumbing
The vent pipe is usually two inches in diameter. The sink and toilet are wet vented together. The drain pipe is connected to the vertical vent pipe at its bottom. The vent pipe must be at least two inches wide. You may be able to use a smaller pipe for sinks or showers, but you should make sure that the pipe is big enough to properly vent the entire room. If you’re not sure how to vent your bathroom plumbing, you should call a licensed professional plumber.
Toilets are the most common fixture that needs to be vented. Luckily, this fixture has the largest vent, so space beneath it shouldn’t be an issue. It also has a three-inch drain that extends to the house main, allowing you to place the vent six feet away from the fixture. However, if you’re worried about space, there’s a way around it. You can also install a vent above the sink.
If you want to vent your bathroom plumbing, you should use a wet vent. You can install this by connecting the sink drain line to the vertical drain leg of the toilet. The drain line for your bathtub or sink should also be one-half inch. Then, you can connect the wet vent to your sink’s drain line. You should make sure that the vent is big enough to reach the rim of the sink.
A clogged vent can cause a number of problems. The water travels downward through the stacks and eventually the main drain line. This horizontal pipe is made of clay or another porous material. Tree roots can work their way into the main drain line and cause wastewater to back up into your home. If you are concerned about the safety of your home plumbing, you can use air admittance valves instead. These are sometimes called cheater vents, but they are not permitted in most states.
Aside from choosing the right vent for your bathroom plumbing system, you also need to decide where to install the vent. You can purchase pipe, fittings, and accessories from a hardware store. The size and type of pipe you need will depend on the amount of waste fluid you want to release. You can ask for help from the sales clerk or a professional plumbing contractor if you need additional advice. Remember, the process will take several weeks, but it’s well worth it in the end.
The oldest way to vent a bathroom plumbing system is to cluster the fixtures around the central stack. Early indoor plumbers noticed that fixtures close to the central stack retained water in traps, while those located at a distance didn’t. Three bathroom fixtures, or three-inches each, can be vented off a single branch or stack vent, eliminating the need for extra branch vents. You can also use a branch vent if you need to.
