replacing check valve on submersable pump???

[jaybob]

My pump is about 280 feet deep and is cycling about every 7 minutes. I think it has been doing this for some time but I just moved it to a well house from a tight crawl space under house so I can diagnose better. I installed a new pressure tank and switch hoping it would help, it did need the tank as there was water on both sides of bladder. If I close the valve I installed before the tank it holds pressure. Does this sound like it is a check valve on the pump? Jay

Hello Jay, Welcome to Terry's Forum.

Yes it does, or maybe a leak in the pipe feeding the top side, tank.

Good Luck on Your project.

Have a great day.

Thanks DonL. Thats what I was afraid of, dont really know how to pull up nearly 300 feet of pipe and pump but I have to figure it out. Hey is the check valve attached to the pump or internal to the pump? Thanks Jay

Most pumps come with an internal check valve, but it is common to add a more reliable brass/bronze one just above the pump. Your drop pipe in the well could be leaking, which causes similar symptoms.

Jay, You might want to wait for a pro on wells to come along for that answer. Depends on the well installer.

They put them up on top side, and also a foot valve could be used at the bottom of the well.

Or attached near the pump. You could put one on the top side, I do believe.

Sounds like a job , but you can DIY.

I do a lot of things that the average DIY'er would not attempt, but I would not try pulling a 300' deep well pump.

All it takes it one mistake and you could end up needing a new well.

Once in a while, it makes a lot of sense to pay a professional for such specialized services.

to stop the leak temporarily, install a check valve before the shut off valve.

If the pump is on Poly pipe, pulling it is rather easy. On steel, you better get a well guy, and unless you are a great DIY'r, let him put it back in - ON POLY PIPE!
