Plumbing Pressure Test

The plumbers left these gauges on the pipes.

I googled to see what they are for. This is one way to test for leaks.

We have water, but it only goes to a faucet in the front yard. This way they can inspect for leaks in the roughed in plumbing lines.

This is how an air pressure water line test is done.

They cap all the stub-outs on our pipes.

They glued a cap to every stub-out with pipe cement.
They can just cut this extra pipe off when they finish installing the plumbing.

They add pressure gauges. This fitting allows an air compressor to fill the pipes with air pressure.

Usually they build the pressure up to 80 psi and leave it for 15 minutes.
If the pressure goes down, they have to look for the leak.

They have left these on for days now.

Everything looks right!
