The REASON RV shower heads drizzle when the OEM shut off is OFF is simple. The HOSE from the faucet to the Shower head is NOT designed for continous 45 plus PSI water pressure. Purchase a metal flexable hose when installing a positive cut off Shower head valve. Doug

Sorry Doug but that's not it.
I used two shut off valves in my RV and confirmed this
The first was a full shut off, a quarter turn ball valve that I ended up using elsewhere. The problem is if you went FULL OFF then when you turned it back on (Depending on several things) you either got a blast of COLD or SUPER HOT water (120)
The "Shower cut off" dribbled. and thus did not do that. and that's why they dribble
The hose is designed to take 40-50-60-78-80 Likely 100 PSI or more for a long long time.
