the max RPM depends on your hose supplying it.

most 60 psi residential 5/8" hose should supply enough water flow for 1500 RPM max.

however there will be an RPM where the muffs quit spraying out the sides..... that is when the RPMS have exceeded the water supply. in some cases that may be only 1000 RPM, or with my 100 psi and 3/4" hose, I can hit almost 4500 RPM

Getting of the thread but I have 125 psi at the meter, but also installed a whole house regulator which brings it down to my adjustment of 65

2-port or 3-port? got a link you can PM me? love the high pressure in the kitchen and the outside faucets, just hate the running toilets.
