"low" and "somewhat" are vague terms.5 sinks that are all connected.
The first and second have low water pressure
and the other 3 are somewhat low also just not as bad.
joecaption said:A salon like that should have had 3/4" main lines ran so they would have the same pressure.
You could have 100 PSI pressure but if the lines are to small the water can not get the fast enough to maintain flow.
Imo, you should start a new thread of your own instead of piggy backing off a 7 year old thread. Makes it more confusing. Plus you will get better results. Nothing wrong with doing it, just saying.I have two Belvedere sinks- one has a normal pressure- another low hot pressure- just had a water heater replaced
