Shower faucet leak detection

i had to change a cartridge in a shower faucet. The connection is recessed into the wall.

Cant check for leaks obviously and I am kinda nervous. All I can do is cross my fingers right?? Or is there another way I can rest easy?

FWIW the plumbing is exposed in the basement ceiling... I can see where the hot and cold lines go into the wall but that is it... no way to see the faucet. Its been a few days now, I don't see any water running down the pipes or falling to the basement floor.

Have you activated the shower head? It could have a leak in the stand pipe that you can't detect until it is pressurized. Changing the cartridge wouldn't have anything to do with the hard pipe connections in the wall cavity. If it leaked, it would leak out into the shower.

Usually you can see the cartridge housing if you leave/take the trimplate off.

If you had a leak.... you'd be able to see it looking up the wall.... it would typically follow the water lines too.
