Why it matters
The J5S is Goulds's 1/2 HP shallow well jet pump: a capacitor-start motor on 115 or 230 V at 3,500 RPM, built-in automatic-reset overload, a stainless steel shaft and a pressure regulator.
Connections are 1-1/4 in suction and 1 in discharge, with a preset 30-50 psi switch.
Who it's for, and who should skip it
Good fit if
- Owners who want a known brand
- Wells to 25 ft
- Replacing an older Goulds
Look elsewhere if
- Wells deeper than about 25 ft
- Homes without a pressure tank
- Owners who won't prime the pump
- Tight budgets
Pros and cons
Pros
- Goulds brand
- Built-in overload
- Pressure regulator
Cons
- Expensive
- 1/2 HP
- Shallow wells only
Limitations to weigh
- Check whether your circuit is 115 V or 230 V before ordering; many well pumps are wired for 230 V.
- Prime the pump casing with water before the first start; jet pumps can't lift water until they're primed.
