This my third system since 2000. Went from 4 tons to 6 tons per contractor recommendation. Getting lots of noise from unit - almost sounds like spraying a garden hose. Pressure tank at 35-50 lbs. ClimateMaster Unit needs about 8-10 gallons per minute. Well pump producing 12+ gallons per minute. I'm thinking a pressure reducer valve would help with this noise that radiates through the house. Would like to add a simple GPM gauge also. Any ideas? Authorized ClimateMaster dealer is not much help.
