Reply To: Pressure Riser or holding tank?

[kookParticipant]

OK, I have some pressures, as measured on the hose bib on back side of house (water comes in from front of house):

Static: 48 psi
Kitchen sink running: 40 psi
Kitchen sink and bathroom sink running: 24 psi!
Kitchen sink, bath sink, washer (warm fill): 6-7 psi !!!!!
Washing machine only (warm fill): 16 psi

Front spigot only: 26 psi
Front spigot and toilet flush: 16 psi

The house is a 2-story. Outside hose bibs are (obviously) on first floor.

Hopefully this provides some usefull information?
