3 months ago I installed a new Basic MultiChoice Rough-in Valve. Capped off the tub and shower with 1/2 iron pipe then and had tile installed.
When I removed Valve cover there was a lot of rust in the water. Almost a sludge.
Installed new Delta Series 14 Cartridge and just a trickel or water flow. Delta service said it must be the cartridge. I relpaced the Cartridge and same thing. Now Delta say it must be the Valve, but I will have to remove tile to replace. I think it unlikely to be the valve. I shut-off the water and poured CLR down from the showerhead line and it seems to come out the Tub spout. After the CLR there is a trickel of water flowing when reassembled, but the improvement might be my imagiation. Still almost zero flow, I am stumped!
