Question 1

is the threads on the valve american pipe [NPT]?

Accepted Answer

Yes. This replaced the diverter valve that the plumber put on when he installed the shower. It is smooth 12"NPT so it works with the washer type fitting that came on the end of the hose, which I am still using. This is far superior to the one the plumber got from his supplier.

Question 2

Can this diverted spray from both outputs at one time to operate fixed and handheld simultaneously?

Accepted Answer

Yes, there is a point in turning the lever where water is allowed through both outlets. HOWEVER, the volume of water reaching the shower heads is limited by the diameter of the shower head elbow. So, if you have regular water pressure like I do, you will experience low water pressure coming out of both outlets. You would need to have very high water pressure reaching your shower head for the double function to be truly satisfying.

Question 3

Why is female inlet collar not attached to body and can't screw it in?

Accepted Answer

The inlet body is not attached in order to allow the user to orient the control lever after attaching it to the outlet pipe from the wall. However, the supplied rubber washer is not sufficient to keep a good seal and prevent leaks, nor is the unit constructed in a way to keep the unit locked in one orientation.  This seems to be an issue for all units of this type, so if you don't prefer a diverter that has a continuous leak and rotates willy-nilly it is probably better to pick a different style of unit that has two points of contact (ex. ASIN: B07YKYFR18) or a multiple outlets controlled from an installed wall control (ex. ASIN: B01MCTPZML)

Question 4

Accepted Answer
