I can't get the water to shut off by turning the integrated H/C shutoffs on the Pr Pf 974-0420 0X8 valve. I turned both screws vertical as well as horizontal and it didn't stop the flow one bit.
This is in a high rise apartment bldg and we are on the top (7th) floor. But why should that matter? Valve is probably 25 -30 years old.
Any ideas?
Just trying to change the cartridge.
Thanks.
