Pump: Goulds 3/4 HP Jet Pump Model C48A94A06 - Two years old
Tank: Wellmate WM0120 (30 gal) pressure tank - New
Well: 20 ft deep & looks to be 4" - has supplied at least 50% more than current demand & never ran dry
Cut in / cut out 42/62
Crudely measured tank drawdown is 4 gallons. Approximate GPM is 11
Takes about 25 seconds to fill the tank & Takes about 22 seconds to drawdown
This system currently supplies 2 homes with a total of 33 outlets (Faucet, Shower, Toilet etc.)
House nearest the pump has 20 outlets - 11 outlets is the maximum possible and 6 is the maximum likely to be used at one time
House adjacent has 13 outlets - 8 outlets is the maximum possible and 4 is the maximum likely to be used at one time
So the combined our likely maximum is 10 GPM
The only issue with our setup is that we have to buy a new pump every five years and that’s due in part to corrosion (above average salt content in the water & air) but primarily due to wear.
Questions:
1. If we keep the two homes on the single supply what size tank should we have?
2. What’s a reasonably priced corrosion resistant ¾ HP jet pump
3. If we put the second house on its own system please suggest a submersible pump that will last in hard water and the appropriate tank size
