How To Replace A PVC Valve ?

By Scott Rodgers

Easy installation and lighter weight has made PVC piping a popular source of bathroom and kitchen plumbing. In order to join the pipes for application that require larger pipe lengths, cement or special adhesive are used. Since it is not possible to reuse the pipe once fitted with the cement, one needs to replace them when required.

To replace any section of the PVC pipe including the PVC valve, one needs to cut apart the pipe and the replaced pipe is attached using couplings and connectors.

Let us discuss some steps one should consider while replacing a PVC valve. In order to work on any pipe length that is already placed, you need to first shut off the water supply to that pipe. Also, gather two couplings, a connector and the PVC valve that is needed to be replaced. Properly measure and mark the pipe length and the rest of the items you will be accommodating with the valve

Next, slowly trim the pipe from the marked place. Also, file the edges of the leftover pipe to make it smooth and even. Moreover, it is better to roughly assemble all the couplings, connectors and the valve before applying any glue or solvent.

Now, measure the total length of the PVC valve and deduct the length of two slip joints located on the couplings. This is the final PVC valve length. Subtract this PVC valve length from the total length between the two couplings. The remaining distance is divided for each cut length of the pipe connectors.

The most important step is to make the measurements of the valve and coupling lengths. For this, firstly measure the original dimension of the valve and decrease that of the slip joints from that. The resultant is the final length of the valve. Deduct this length from the couplings length. You are now left with the place to accommodate the connectors, one on each side.

Brush away all the build- ups and the dirt from the inside and outside of the joints made in all the components. Lay on some cement or the binding solvent so as to adhere the couplings and the connectors permanently.

No doubt, replacing a PVC valve is not a child's play, even then a little knowledge of the plumbing can help the homeowners to carry out the project themselves. - 30517
