Here is the deal - I got bathroom remodeled. Moen 82603 single handle valve. When the water is coming out the fastest (mixing hot/cold) water comes out of the shower head. The person (not me) I had helping installed the valve at about 48" from tub floor or about 30" above faucet. The directions clearly stated the valve can't be more than 11" above the faucet. So basically the new shower wall is toast since if I have to have this re-done, and the valve lowered, it's a complete re-do.
Question? What are some better options? I can get into the plumbing by removing the drywall in the adjacent room.
