pressure correction after reading it
guys at water company came by during a heavy rains period and gave me a reading for the pressure at the point their pipe entered my inner house water circuit. Thing is - I highly doubt that the pressure value during the hot summer will be the same. Any percentage by which I could reduce it in order to correctly plan my irrigation system ?
I am not going to wait until too late to read it again, so I'll have to work it out with some guesstimate.
