How to Install Plumbing in Your Bathroom
When it comes to plumbing, bathroom sinks, tubs and toilets require a lot of effort; however, the task is not as difficult as one may think. With the necessary tools and basic knowledge of plumbing, the task is not difficult at all. Follow these steps to install bathroom plumbing.
Design the Bathroom and Obtain Building Permit
The first step to installing bathroom plumbing is designing the bathroom layout and presenting it to the proper authorities to obtain a building permit. Check the local building codes first.
Determine Necessary Pipe Size
Measure the diameter of the supply line. Make sure that the pipes to be used in the installation process will match those that are used in the household. Record the required fittings before heading to the supply shop. Also determine whether to install a P-trap or an S-trap for the drainage system. Make an estimate of the entire length of the pipes to be used and purchase the necessary materials from a supply store.
Connect the Sink Pipes
Measure the distance from the sink to the sink stub-in and cut a PVC pipe accordingly. Fit the pipe to the stub-in first and apply a PVC Primer to the connection. Apply a liberal amount of cement to the primer and join the pieces together. Hold the pieces for 30-seconds.
Connect Toilet Pipes and Water Lines
Follow the same process for the pipes that connect the toilet to the drainage pipe. Start by measuring the needed pipes, cut them, and follow the previous connection guidelines. For the water supply connections, turn-off the water before installing the pipes. Cut the pipes according to the dimensions in the bathroom plan. When connecting fittings to the water supply pipes, wrap the male threads with Teflon tape. Use an adjustable wrench to tighten the connections.
Install the Drain Pipe
Determine the length of the drain pipe that will run below the bathroom and cut the pipes according to size. Make sure that the drainpipe is installed at a slightly sloped angle. Connect the pipe to the drainage line by applying primer and cement. Connect the drainage pipe to the pipes on the bathtub, sink, and toilet.
