You really should call me or at least read the Cycle Stop Valve web page. I hate to highjack someone else's thread, but I appreciate yet another opportunity to explain why the CSV is better than a VFD, the same way I have been doing since 1993. One of the first things a CSV is better at than...

This new info shows the screen from 230' to 240'. That makes more sense. Like was said the well needs to be clear to 240' to utilize the screen. If the well has filled in above the screen that could be a very good reason for low production. Could probably clean out the well with the...

Oh boy! You must be new here. Glad to have you but you are in for a ride if you are going to try and prove that one. I have about 30 something years experience solving all the problems with VFD's by replacing them with Cycle Stop Valves or CSV's. There are probably a few hundred threads just...

Only going 70' the 1" should be large enough. But 1 1/4" would not hurt. PVC is my favorite too. I don't even like galvanized on the ends. I would use brass if metal was needed.

Pipe could also be stuck in the well. Sometimes all you can do is pull harder until something breaks. I have seen them come loose and the pipe spring up and slam back down. Can be fairly violent. Heat might help burn the rubber or soften it.

Never heard it put quite that way. I am guessing it has a screen on the end of the casing as 230' and is filled to 225' with gravel. If that is the case, air lifting has no screen to clean and may blow out the gravel pack. Wells are drilled differently in different areas and that method is...

Lol! Not too many people able to change out or even check a capacitor, much less a MOV. If the expected life is 10-15 years, I'll bet the average life is half that. Seven years has always been the average life of submersible pumps as they are designed with planned obsolescence in mind. Of...

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.
