We have a Moen Posi-temp Temperature control located in a shower stall. It will control the temperature very good, but you cannot cut down on the volume coming out of the shower head. (its either on or its off)
I would like to cut down on the volume (probably to half) by adding a adjusting valve just before the shower head, or install a valve on the each of the supply pipes coming in that feed the control.
Does anyone know if this will effect the temp control (cartridge) in any adverse way.? Thanks
