I am suspecting my well booster pump is causing errosion corrosion inside my house where 3/4" copper exists. It is 2 HP and operates at 25-44 GPM. The 1" line outside the house tees off into the fire sprinkler system which is supposed to require 20 GPM.
Is errosion corrosion likely here? Getting a smaller booster pump is complicated by the fire sprinkler requirements. Is there a 10 GPM flow rate limiter I can put at the house (after tee to fire sprinkler system) that would help?
