Well pump replacement

[Valofthenorth]

I’m going to be replacing my submersible well pump and I’m wondering if there’s a way to tell the horsepower rating without pulling pump. There are no tags or markings of well depth or pump size. But I believe it to be 200’ or less it’s connected to 1”poly pipe 2 wire system

You can get close by measuring the current while the pump is pumping. Use a clamp-around ammeter around one hot wire.

7 gpm 3/4 HP would be a guess for a house, knowing no more. 3/4 would be about 6.8 amps typically.

Try looking down the well with a bright flashlight at night, or directing the sun down the well with a mirror in the day. You can also drop an ice cube to get some idea of how far the water is.
