    Best way to fix a pvc pipe leak

    Let me first start off by saying I know I should just replace the piping. However this is the piece attached to my hayward multiport valve and to replace it I would have to replace the whole valve along with several pipes that were glued into it. I tried the method of adding extra pvc cement to the joint. That worked for about a year. I tried it again this year and it's just not going to cut it. I was going to remove the glue around the joint and start fresh but looking for the best method. Thanks in advance.

    Got a picture? A lot of pool plumbing is dual-sized. You might be able to stick the bigger connector on the outside and then us a reducer to bring it back down.

    This is the valve unit. It's the side straight piece that's leaking. Not at the o ring but at where it goes into the valve body.

    It connects to a sand filter. I don't know what you're hoping to see.

    I dunno, maybe an arrow or something showing which piece is actually leaking? If it's what I think, maybe some epoxy putty.

    Sorry my bad, thought the text I posted was enough. Here is the pic. Obviously red arrow is the leak.

    Re: Best way to fix a pvc pipe leak

    As you have discovered, PVC cement won't cut it for a repair like that. PVC joints are made by solvent welding the two parts together. The cement used softens the material and allows both sides to "melt together. Once the solvents evaporate, the joint re-hardens. The "glue" itself has no structural strength and thus won't last long. Sand the area at the crack/leak and apply some JB weld as mentioned. Properly applied that will outlast the part it is on.
