## Description

Sharkbite 1/2 Inch MNPT Bathroom Shower Test Plug, 25828Z

Review: Worked great, read the whole thing - This did great. After I plumbed my whole bathroom with pex I used this to test for leaks. I left the shower handle on for about a week to make sure I had no issues. When I turned the shower handle off and removed this plug I had an issue. For whatever reason both connections at the shower manifold started leaking. I was able to stop it by tightening the fittings, but I never would have guessed with the shower handle closed the manifold would leak after a week of being on.
Review: sweet item! - This allows you to plug your new shower outlet so you can pressure test the shower valve before closing up the walls in case of any leaks. This worked great. I actually used this same one 3 times so far. This product was a great idea and so easy to use since it seals with a rubber washer. No need to use teflon tape or paste on it.
