Greetings All,
I have a new bathroom on the 2nd floor, and the shower has a low pressure
problem. The sink and toilet are ok, but obviously they use much less water
than the shower. I have city water using a 1 1/2" main line and the vertical
risers are 1". Although the shower has many fixtures, (6 body sprays, 1
rainhead, 1 fixed head and 1 handheld), it seems as if the pressure needs to
be higher. I realize it's impractical (and overkill) to use all of those
heads at the same time, but when using just the 6 body sprays alone, the
flow isn't what it should be. The mixing valve is rated high enough to run
them all at the same time. The first floor shower has a 3 body spray set
up, along with 2 fixed heads and the flow there is fine. I have disassembled
the heads to make sure they aren't clogged and everything checks out ok.

All of that being said, I'm thinking about installing a water pressure
booster pump. I would think just a pump alone wouldn't be enough, isn't some
sort of reservoir needed also? It seems as if the pump would pull the water
faster than the city main could supply it. Has anyone gone through the same
situation? Thanks as always, Mark
