A PVC valve helps to regulate, lengthen and connect PVC piping for plumbing and other services. The PVC valve will typically fail before any other part of the pipe. This is usually because the PVC valve is an addition to the pipe as a whole or they have not been installed properly. Your basement can have PVC pipe installed, but usually it will be found outside and under the ground. It will be used for plumbing from and to the home, waste removal, water run-off and water recycling. If a PVC valve fails, you will lose pressure and notice a large amount of water in the yard or basement. A plumber can cost a small fortune, especially when replacing a PVC valve is not that difficult. There are some things you need to keep in mind when doing the replacement, and the article below will share the most common with you.
1. Stop the Water Flow
Failing to turn off the source using the PVC pipe will cause a huge mess. Make sure that whatever is using the PVC pipe is either turned off or not used.
2. Removing the Old PVC Valve
A PVC valve is always (or it should be) attached to the PVC pipe using sealer that doubles as a glue. This makes removing the valve difficult. The only way to do it at this point is to cut away the PVC pipe. Where the PVC valve meets the pipe, use a hacksaw or reciprocating saw to cut through the pipe. You can then lift out the valve section.
3. Make Sure it Fits
The PVC valve should not easily slide onto the ends of the pipe. If it does, then you have chosen the wrong size of the valve. In order to create a seal that is watertight, you need a PVC valve that is snug. You will probably need to work at putting the valve on the pipe. If the valve can slide on easily, then the pressure in the pipe will be able to cause the valve to burst and split off the pipe.
4. Long Enough Section
If the PVC valve is too short, it can easily be pushed off the pipe by pressure. It is important to make sure the PVC valve is long enough to cover several inches of piping on either side. The PVC valve must be able to join both sides of the pipe equally. Measure the current PVC valve and choose a new one that is several inches longer.
5. Double Seal
It is often the most common mistake to seal either the inside of the pipe or the outside but not both. Remember that PVC pipe sealer prevents water from escaping the pipe but is also glue which keeps the pieces together. Make sure you apply the sealer to the inside of both the valve and the pipe and then on the outside where they connect.
