pressure test drain

[Nate848]

I got everything set up and it seems to held 5psi for about 15 to 20 min then it dropped 1 to 1.5 psi after 30 mins. Should I worry about this at all or is it fine since it did not drop in the first 15 minutes?


Thanks

You have a leak. Can you fill with water?

 

[Nate848]

yes but im afraid of the weight on the pipes. Its about 100 foot of 3inch and another 75 foot of 1.5 and 2inch.

if the pipe will not hold the weight of a water test, it is not installed correctly
pvs should be supported every 4' and on both sides of each fitting

Where I plumb from, drainage pipes must hold a 3m column of water for 15 minutes.

If the supports holding the piping will not support the weight of the pipes filled with water, it must be re done.
