Note: Lots of similar questions, but they mostly deal with either a sudden, unexplained drop in water pressure, or with water pressure that has always been low.
In my case, the situation is as follows:
- MIL's house had awesome showers with decent pressure.
- But, as it turns out, the main water pressure was too high and damaged some valves on the heater. A plumber came, fixed stuff, and installed pressure limiting device right at the main.
- There's no gauge at the water main so I don't know what it's set to, like 40 or 50 PSI?
- Now with that pressure limited, the showers in the house are pretty disappointing. I measured the flow rate on one of them and got something like 1.5 GPM, whereas the heads themselves should be rated for 2.5 GPM.
Now what can I do to enhance the shower experience again? Could it be that somewhere in the pipe that goes to the shower there's a pressure limiting device as well, which made sense back in the days of high main pressure but is overkill now that main pressure is limited?
Or is it that the heads that were meant for 2.5 GPM just are very disappointing when pressure is low and I should go and get a head that's meant for lower pressure like 1.5 GPM?
