Ok, this is going to sound like a lazy question, because it is. Anyone know if uniform code lists a minimum static pressure for potable water in municipalities? Here in the KC area, my most common problem is high pressure. I had the guage pop to over 135psi the other day. I have a neighborhood with 3-6 year old WORKING systems (well until this summer) that are now running less than 10gpm through 5/8 meters. I have static daytime pressures of less than 35psi. I seem to remember when I was in DFW being told that one of the areas there that had pressures this low were being fined by the fire marshal because they were not providing adequate pressure to the fire hydrants with pressures less than 40psi. I was told that if the working pressure drops below 20psi, you can shell a pumper. It is possible for those cloth hoses to collapse and be sucked up into the pump.........I don't know if that is true, but while discussing low pressures that was what I was told back then.
