Re: What is the quietest fresh water pump?
Sounds like you need to get a bicycle pump and reinflate the bladder.. if the pump's coming on more than every 3 or 4 tap openings (exc for filling a sink, etc) then the bladder pressure is too low.
It should say on the tank what the pressure should be.. they make some nice compact bicycle pumps with built in gauges nowadays..
All these pumps make noise.. no reason why you can't mask the noise with an insulated enclosure, but a properly setup accumulator really quiets things down since the pump runs far less often.
