How to fixing a slight PVC leak?

[EBR]

Like it says -- I've got a PVC joint that turns out to have a slight leak. Normally, I'd cut out the offending coupling and replace with a new one -- but it's in a pretty awkward location and is not be easy to reach. Is there a way to seal it? I doubt that glopping more PVC cement on the joint would work, but what about something like the stuff to join acrylic? (I forgot the brand name -- Weld On, I think?)

 

Any suggestions welcome.

Thanks.

I had a leak on a bulkhead when I fist setup my tank. I didn't care to much becasue it was over the sump. Eventually salt creep stopped the leaking. just my 2cents

WeldOn sounds like an idea. You might also look for a material meant to repair boats - esp something for underwater repair. You could also call a plumbing supply house like Ferguson and ask what they have for fixing such a problem.

Matt,

You might try, after switching off the pumps, rubbing primer again on the joint. That seems to dissolve some of the glue. Then put a nice coat of PVC glue on the joint again. Wait a few minutes before switching on the pumps again.

You may want to consider replacing the piping with some SPA flex. I know that it is hard to get to, but what concerns me is that you say you have several leaks. It might be worth the time to tear it apart and replace the piping with SPA flex.

Replace it (I wrote a long post and then lost my connection and am too lazy to retype it). Long story short, glopping PVC solvent won't guarantee a fix and neither will acrylic solvent for which you'll need to clean the pipe and make sure it's dry for the capillary action to work.
