Hi Kjpro,
height from the feed water regulator valve on the boiler system up to
the heighest radiator is 28 feet.

My Watts Regulator spec sheet says to calculate pressure, take this
height, multiply by .43 and add 3 pounds. That comes out to 15.04.
Pressure is set at 15 pounds.

What would happen if I increase the pressure beyond what is required?
Would it force the water to rise to the top of the heighest radiator?


Close off the valve to the expansion tank and raise the pressure from the
PRV, make note of where the screw was and how many turns you made, bleed
your radiator(s), go backdown and reset the PRV to previous place, reopen
expasion tank valve.
