Drain pipe leaks
I am building an addition and have a very tight area in the wall for the washer and after cramming it all in there using lots of connectors to get it to fit within the 16" studs it leaks in a few places but very little. It has not been inspected yet but local inspectors require me to fill the entire drain line up to the vent outlet in the roof so though the pressure is little it will have some pressure. The leaks are at the connectors though I used the purple primer and the clear glue. Honestly I can't see how it could leak but it does. Is there a way to avoid having to cut it all out and do it all over again?
Thanks in advance. |

Probably not, but let's see if we can figure out what went wrong. Color of pipes? Black or white or yellowish? Typical size of the pipes used? What does the glue container say? PVC, CPVC, ABS Were pipes cut square? Did you debur? Did you do a dry fit? There is another step, infortunately and that's the cleaner |

It's the white PVC and the pipes were cut straight. I cleaned off burrs but didn't use a cleaner per se but I did make sure the pieces were clean. I used the purple primer. I think the major problem was because the area was so tight it was next near impossible to twist the fittings properly after gluing because I couldn't get my hand all the way around the pieces, usually. Dry fit was a necessity due to the tight fit. I really don't want to start over again because the space isn't going to get any less tight and then I'll just increase the amount of connectors. |

You may have to re-do them. There is a drill that's made so you can drill out a fitting. PlumbingSupply.com - PVC fitting savers, PVC/ABS fitting reamers, socket saving RamBit for PVC plastics Also, you should be able to get "repair couplings" which I haven't used before. You can also use Proflex connectors too. They look like a rubber coupling with a stainless outside and hose clamps. |

Yeah that's what I'm afraid of. It's not really that much pipe it's just really tight... never heard of the repair couplings but I did see someone mention something about 'repair tape'. Thank you though for taking a look. Perhaps I'll take the extra step and use the cleaner as well as a precaution. Beats doing it all over again, again, LOL Thanks |

How many leaks do you have and how bad are they? The hubs of PVC fittings are tapered a bit so when you glue them they must be seated. Having said that if the leaks aren't too bad you could: 1) use repair tape on the joints, 2) Dry off the joints and prime the outside and pour PVC cement around the joints to caulk them **OR** 3) Do the entire thing over again. Good luck, Tom |

Hi Shama... You said this was going to be inspected and you were required to fill the system with water to the roof for the test... correct? If so, as much as you won't like to hear it, you're going to need to cut this out and start all over. Here, during the test you will be holding 3-5 PSI and I promise you that little leak will turn into a big leak. You cannot use repair tape and most likely your inspector won't like seeing a proflex repair clamp in new work, but you can use a PVC repair coupling. If the inspector finds anything like that they could start to be even harder on you and your work... never a good thing! Save yourself the headaches with this and just replace the faulty work. You will feel better in the end as the inspector passes all of this and you have no leaks now or in the future! Just my thoughts... Mark PS: If it makes it easier for you to work with the pipe/fittings you can always cut the nails at the top and bottom of a stud and move it over slightly... ;) |
