    Ideal street pressure

    What is the ideal water pressure coming into a house?

    on what? domestic water ?

    we have a few piped in waters here...steam ,heateded glycol ,and domestic water ..then theres the Fire sprinkelers ...i havent latched a clue what the available pressure and volume you might need ...perhaps that would be a good place to start, then find out from the utilities if that can be delivered and where the take off is on thier mains...

    It depends.......

    ....on what the local water utility can deliver! Other things can factor in also, like how "taxed" the system is, how full the tower(s) are, etc. The pressure can vary quite a bit depending on these variables.

    Here in my town, the average street pressure is around 65 psi. I've seen places, though, where it could push 100 psi. A good quality pressure regulater in the main line is money well spent.

    Well having 100 psi available is a norm here...

    then put a regulator on the house side, this really should be Matched to your load calculation buh for a general idea...a steady 60 psi in the house should be fine...many people dial it back to 45 psi and consider that fine...comming out of a well ,...that tends to cost alot extra for the controls etc. however the 30 -50 and 40 -60 psi regulators are widely used in homes pulling off a well.these regulators control the operating limits and work to maintain pressure somewhere in the vicinity of thier upper and lower limits.

    Water pressure

    Down here, 120 psi at the street is about the norm. Inside the house, it all depends on the homeowner. When I installed a pressure reducer and set it for 60 pounds, my bride almost killed me because the pressure was too low.

    I have seen pressures in some areas go from 120 pounds to 60 pounds and back to 120 in less time than it takes to read this sentence. And that was with the valves to the building turned off.

    our code

    allows for 55psi or we have to put on a pressure reducing valve. You have to size the meter and supply to available pressure and use so as so many have said, it all depends

    the penalty for failing to reduce pressure

    into the home may be burst hoses or failed water inlet valves. Pressure reducers are cheap insurance.
