All depends on how fast that 3' of water can come into the casing. You could try it and see. If a pitcher pump and/or jet pump can't draw much volume, you can go deeper. Any others in your area for reference?

With enough air to do the job, I am not sure you can keep the plastic pipe in the well. It will nearly shoot steel pipe straight up like a rocket. But if you can get the pipe to stay in the well, dabbing it down in the sediment will bring the sediment up, and the sediment then becomes material...

A little longer run time at reduced amperage is always better for the pump/motor than short run times at high amperage. Remember there is absolutely zero friction in a submersible motor once it is up and running about 50% speed. There is only heat build up that needs to be dissipated. Reduced...

Grundfos usually makes good pumps. But a leaking seal rusts the shaft and washes the grease out of the front motor bearing. It can also get water into the windings. Grundfos should have replaced it. But the seal could have been damaged form running dry, like taking too long to prime or...

A 5 GPM, 1HP builds 560' of head. That is 242 PSI and is the max pressure the pipe will see. Take off the 155' to static from the 560' the pump can build, and you get 405', which is the same as 175 PSI, and also the back pressure at the CSV. A 7GPM, 3/4HP only builds 400' max (173 PSI on the...

A setting of 6 is probably ok. As long as it shuts off and says DRY when the water stops coming. But it looks at that for about 10 seconds before shutting the pump off, so that also sounds ok. Restricting the pump could help, as you could make the pump run for 4-5 minutes instead of 2, which...

Lol. I didn't notice we picked up an old thread. Most people don't come back after a year or two to see if there are anymore comments.

Glad you got it working. But we know how it will go. About the third time you replace that $800 CU301 box you will figure out how pump systems should be controlled. :) There are really only two ways to control a pump. One makes the installer happy. The other makes the customer happy.

With the Schrader on the bottom, if the tank is bad water will come out as soon as you push in the valve core. If the problem is intermittent, it may be tripping the overload in the motor.

The tank is most likely bad, but it was destroyed because the CU301 has failed. See if any water comes out the Schrader valve on the tank and you will know it is bad. You can replace the CU301 and transducer with a regular pressure switch. But you will then either need a big pressure tank or...

Glad you got it working. But a 30 gallon tank only holds 7 gallons of water. The tank is not why you haven't ran out of water. Bigger tanks are not better with a low producing well. The well pump sees the tank as an extra 7 gallons to supply. When the tank is full, you can get 7 gallons as...

You are not suppose to ask questions, just order a new CU301 and maybe a pressure tank. That is what those things are designed for. Lol. I would get a 40/60 switch from the store and replace the Transducer, also removing the CU301 completely. You can tighten the large adjustment screw in the...

But a low pressure cut off switch with the lever will save the pump if it is really losing prime.

The bolts just tighten the rubber gasket in the middle. Just takes a little more pull on the pipe to get the seal to slide out if the bolts are tight.

Pumps don't have to be that expensive. Here is one I picked quickly because of price. I look for a cast iron pump housing instead of plastic and one that builds a max pressure of at least 70 so it will work with a 40/60 switch. It is not so much the brand of pump but rather how it is controlled...
