Poor Water Pressure in Shower - Symmons Temptrol Unit
We have a Symmons Temptrol Model A shower/bath unit installed which has very poor water pressure when using the shower head. The bath facet pressure is adequate but does diminish when increasing the hot water temperature. When switching to the shower the water pressure slows to a dribble. Interestingly, the sink facets in the same bathroom have decent water pressure.
I have cleaned the shower head and removed the water saving value to no avail. Any ideas for next steps?
Thanks!
