I am the operator of 2 different RO systems one on an 80 foot westbay sunship and one at a large oceanfront residence. if memory serves they both start producing at around 400 psi. the one on the yacht (60 gph searecovery unit) operates at 600 and the large home unit (6 gallon per minute) at 800 psi.
