Leaking aqua UV sterilizer.. Need help!

Thread sealant tape is for thread joints. The leak is coming from the glued section.

I've never tried this, so I'm simply theorizing with you at this point...

I suspect PVC cement would react to rubber very similar to the way it does PVC. If this is correct, find a piece of (about) 2" wide rubber (thickness isn't critical)... put PVC Cement around the leaking seam and extending the PVC cement coating 1" above and 1" below the leaky seam, then wrap the rubber over the leaky seam.

Lets hope this works.. I will update you guys tomorrow

Just go to home depot and buy a rubber coupling. It cames with two hose clamps. Looks like you have a union that would allow you disconnect and slip the coupling right over the leaking section. The hose clamp will hold the pressure.

If the PVC cement fails I will do this.. This seems like it would work pretty well though.. Hopefully I will be ablet o find the rubber coupling!

Try using a thread sealant tape......

Not sure how this would work but if both the above fail I will look into this..

I guess that scratches that idea out. I was thinking it was some type of teflon tape, if it is.. it definitely would not work.

It worked for me. You just need to use a lot of it....like using a whole roll on one leak.

I have a koi pond business and have installed and repaired many UV sterilizers with help from Aqua Ultraviolet on problems like this. The solvent did not chemically fuse the PVC sections together properly allowing leakage. JB Weld epoxy applied outside will hold it for a short period but eventually the UV exposure will degrade it. The blue glue (Christy Red Hot) will not seal the leak because it is not a filler.
Mechanically sealing it with a coupling is best. $3.00 ea.

it looks like a DIY UV sterlizer, so why not just take the bulb out and make another one.

Great info..

I think I will run out tomorrow and find some rubber couplings.. Seems like the best way to seal it for the long run.
