Sorry for the long thread - Here are the facts: Cuthbert 3 valve shower; 35 yrs old fixture in a condo; Diverter was replaced last year; noticed water coming out of the spout is strong and steady. When the water is sent to the shower head, the pressure is noticeably less. Noticed the temperature is not balanced - I have to turn up the hot water all the way, while decreasing the cold water to almost nothing in order to get a comfortable temp. When I divert the water back to the spout, the temp is very hot.
Without any changes to the water flow, the shower temperature will all of a sudden go to 'freezing cold' (this is where it's possessed). I turned off the cold water to still receive cold water for another 15 seconds before the hot returns. If I turn to diverter to the spout and turn it back to the shower, the water temps is fine, only to go back to cold.
I replaced the diverter only to get the same result. The diverter has four 1/4" holes opposite to each other. Thinking it was positional, I aligned the holes at 90 degrees to the hot and cold, 45 degrees, and in-between to no effect. I looked inside the housing for all three valves - no clogs can be seen - if it works for the spout could it be the pipe going to the shower? Doesn't make sense that I have to turn down the cold water.
Replaced both hot and cold valves and they look fine.
To summarize, water temp and pressure is 100% ok when coming out of the spout; sending it up to the shower is less than ideal. It's almost as if the cold water overrides the hot water. I've tinkered with it for a couple of hours to no success. It looks simple enough in design.
What gives?
