We just renovated a bathroom with Grohe shower components (19988001 thermostatic shower valve, 35026000 rough-in). I've attached a picture of the rough-in installation.
When the shower valve was installed and the water was turned on, there was no "neutral" position where the water could be shut off. There would either be a decent amount of water coming out of either the overhead shower of the hand shower no matter where the adjustment lever was pointed.
Our contractor said the cartridge was bad, so I called Grohe and they send me a new one within a week. With the new cartridge installed it is 99.5% fixed, but unfortunately there is still a very very slow dribble of water out of the hand shower when the adjustment lever is in the neutral position.
Does it seem possible that two brand new cartridges would have this problem? I'm worried that there is something wrong behind the walls, but with my low-level understanding of the rough-in box I can't understand how that could be the problem.
Any advice is appreciated.
