Hi Guys,
What air pressure to pre-charge an expansion tank?
- Tank comes pre-charged to the 40psi (this looks to low).
- I would like to maintain 50psi in my house plumbing.
(Is this OK? City water pressure is 90psi so I have room to play).
- "Watts" recommendation is to pre-charge tank to the working
pressure (this seems to be very logical and makes sense).
- Master_Plumber_Mark recommended pumping it to about 60psi
(why the higher air pressure would be better then equal to the
system working?)
So, what is the correct answer? Mark?
Thank you,
- Vitaliy
