    what materials are you using? pvc? and if so are you using pvc weld?

    please remember that both the inner of the grey pvc fitting and the outer edge of the blue pvc pipe needs to have the smooth surface abraded off to allow the pvc weld to properly bond the two together..

    pictures will help greatly to establish what is going on...

    I can, depends on the project I work on.

    PVC weld is glue that bonds the pipes and elbows together.
    If the leak is on the connection, you can switch off the return, and smear a good load over the joint. Hopefully sealing it.

    So in my opinion there are a few things you can do. I will list them in order:

    1. Do it properly, cut the pipe (if you didn't use any pvc weld you might get away with actually not having to cut). Sand BOTH the exterior of the blue PVC pipe and the inside of the joint till its nice and rough. Then apply PVC weld (a MUST) the most common one to use is Tanget *check spelling.

    2. You get silicone sealing tape for things like this. Its a tape that binds to itself and seals the joint. Something I ALWAYS keep with me. It has saved my a$$ many times whilst I got the right equipment. - builders, home depo etc has it

    3. Hardly works under pressure - silicone (marine) around the leak.

    If you turning the pumps off and they off while you were at work you could already have applied and let the tanget dry for half the time it requires.

    The bottle says 24 hours for curing and its right but I have used it on high pressure areas within 12 hours without an issue.

    Good luck

    One other option often left out now that I am thinking of it is replace all the hard blue piping with some plastic flexi pipe, I did this on my baby tank and it works really really well!
