AS shower unit has low hot water pressure
One of my two showers has low hot water pressure. The other shower works perfect.
It's an American Standard single handle unit. Cold water pressure is fine. I had the same issue 3 yrs ago and I believe they shipped a cartridge which did the job. I again received a cartridge and installed it. Hot water pressure is still very low. What gives? What else can I do?
Thanks in advance.
