Question
QUESTION: I installed a grohe shower bodie W/tub outlet. When I turn water on water sort of pours from shower head. I used pex/plasctic for the supply and shower and copper for the tub connection. Grohe mentioned in diagrams not to use pex for tub connection.
I am loosing my mind this is the second time this happen to me.
Ther must be a reason ? I changed the cartridge still got the problem.
Thanks Keith
ANSWER: Hi Keith,
Grohe probably said no PEX on the tub spout due to lack of support for the spout. People tend to rest their foot on it.
There is something wrong with the diverter. Either there is none and the water is just taking the path of least resistance or it is malfunctioning. The default water path is to the spout and sending water to the shower head requires some action. Pushing a button, lifting a knob or turning a handle/lever. Without knowing the model number etc. I cannot look up the tech data. I would contact Grohe directly via this webpage: http://www.groheamerica.com/p/25_16615.html
Good Luck,
Dana

QUESTION: Would using pex material for the water supply and to supply the shower have any effect on the shower bodie to make water stream from shower head.the model # is 35015 universal pressure balance rough in valve. I followed all directions I will open the diverter and clean, I followed the 8"-18" rule of separation.
thanks again Keith...
Answer
Hi Keith,
Using PEX should make no difference on the supply inlets but..... See here: http://www.groheamerica.com/lib/1/tpi/1288624.pdf (you should have this manual, it should have come with the valve body)
If you look on page 5 on the upper right side it says "do not use PEX on the outlet sides or the water will "stack" and come out the shower head." By "stack" I think they mean it is restricted enough to cause your problem. Obviously, this is not the first time they have encountered this problem. I think it you change the shower feed riser to 1/2 inch copper, it should be okay.
I like the idea of the built in service stops. It's a bummer when you have to shut down the whole house to service a tub/shower valve.
As we say in the computer field, RTFM. "Read the freaking manual" LOL I've shot my self in the foot a few times too.
Good Luck,
Dana
