After 2 solid weeks of running my heat-pump, the deep well pump (down the well) that was here when I moved in seems to be giving up on me... I have nooo idea why - it just isn't flowing enough water suddenly and the heat-pump shuts off on freeze-up protection.
Now, I've been TOLD that the pump is a 2 wire self starting pump... it only has 2 wires run out to it so that's really all I have to go by as well.
It is only 1/2 HP as well - which barely meets the flow requirements as it, but it did none-the-less (and the price was right - it was here when we moved in)
I realize I'm likely looking at a fair bit of coin for a new pump... anyone know of something used around?

you won't find used and if you do its gonna be close to the same price as new...
HP rating is not what you need to worry about, you need to worry about GPM of the pump..
I have 1/2hp that flow 15gpm, or I have 1/2hp that flow 5gpm.
You need to find out how many GPM your heat pump requires and then how many GPM your house is using. Then you can find a pump to do the job. I am assuming your well is supplying both the heat pump and house use.
Saying its a 2 wire just means it has the starter built into the motor, which means you have no control box on the wall, not much of a difference in price between the two.
Where is your house at? Would be nice to know what the pump is set at and what GPM was in it.
If you are having a problem with water flow, is it possible your well is running dry? being over pumped? any idea how far from surface your water is?
I have a dug well for the house, and a Jet Pump on it - the heat pump is on a drilled well which is high in LimeStone (iirc - some heavy mineral anyways) (I live in Alton - so not surprising)
I realize about the self starting bit meaning the starter is built into the motor - it just sucks that I'm limited to only self starting pumps - wasn't sure if it'd greatly limit what I have or not. (My father has a spare pump, but it requires a starter box)
The well was supposed to be yielding 30GPM but - again - hard water.
The unit requires between 8-12 GPM. We had timed it when we started and we were filling a 5gallon pail in about 30-35seconds.
The pump is about 150 ft down with the water being about 100 ft down(or so I thought - my father seems to think different) (we had it out this summer, burred water lines, installed a pit-less adapter, etc)
Hmm... I am somewhat doubtful about the water level - I had run it for almost 2 days straight back in the summer trying to get it to clear up so we could use it to water the horses.
I have another thermistor I am to try on the heat-pump - apparently you can actually bring the water level down below freezing as long as it is moving. This is done very regularly on these water-source installs (or so we are told).
We were also told that we may need to up the pressure of the water a bit (that maybe we're not running high enough pressure for the switch we have) and that bringing up the pressure will reduce the amperage the pump draws? I have 1" run from the pump to the house - and the smallest it gets is 3/4" pex. It was suggested I install a ball valve on the outlet side with a gauge and set it up so the pressure comes up some. Thoughts?
Second off - we've determined the issue seems to be that the pump isn't pumping consistently - its like the well isn't making enough water - so it flows like crazy, then the pressure/water flow drops.... stops... then flows like crazy again.
In looking at my well it appears the water is a loooong way down - I am thinking maybe the pump should be deeper...
You can install an overload sensor in your house instead of float sensor when the water get low the pump speed up the sensor trip the pump. they are programmable,when the float started to fail at work I just abandoned them there and installed those 179.00 a pop. I run 3 well to supply a twin pad rink I also used sonar sensor for storage tank level 1000.00 each. a 100' is not much for storage capacity my well are drilled to 400' because you reach water at 100' you should go deeper that water column is your storage, recovery happens over time

Going deeper with the well would be great - if I had that option financially right now... Not too sure what I'm going to do honestly... Maybe install dad's old air-source heatpump for the winter... if this keeps up.
What are the chances the seams in the ground may open up some as I keep using the pump?
