We have a Moentrol single handle shower control. the wate flow on the
cold side is getting lower and lower.. I reoplaced the cartidge (Moen
1225-B) and there was now improvement.
I also took the entire unit apart. There seems to be full water flow
up to the cold water check valve, but low flow after the presure
balancer.
Does any one have any suggestions?

Could the presure balancer be doing its job because the hot pressure is
also low?
