Hope someone out there can help with this one ... or at least suggest a fix.
We have recently build a new concession stand at the local baseball diamond and as we were getting ready for the final inspection found that there is a leak somewhere in the drain line.
When the drains were initially installed we pressure tested with air and the line held pressure with no drop. After making the final connections at the sinks and such we inserted the "big black rubber plug" in the cleanout outside the building and inflated it. After running water into all the sinks and getting water to stand in everything we found that after approx 10 mins the water had all drained.
Now, to the question ...
Is there any fix out there to try before we start busting concrete to try and find the problem?
I would appreciate any help that anyone out there can offer before we start making a complete mess of the near finished project. THANKS in advance!!!
The first thing would be to check the test ball and make sure it was inflated to sufficient pressure to hold the water, and that it was inserted properly to completely seal the pipe.
