Testing a new faucet

[penobscotman]

I'm installing a shower (fibreglas enclosure) and I'm about to start on the rough plumbing. Copper, sweated fittings. Is there any way to test the plumbing for leaks before I install shower walls and the shower cartridge, etc.?

Install the cartridge and turn on the water.

I guess my question was almost too dumb to be answered, but thanks! Won't the water spray out? I guess I will find out!

When testing a shower valve, you will want a test nipple with cap.
When installing the trim, you remove that and install the shower arm.

They're out there.

If it "sprays out" then you have a leak, and you would have it no matter how you tested the faucet.

I did everything everyone said -- no leaks. Thanks.
