I have a submersible pump/deep well. Well-X-Trol Model WX-202 pressure tank, Square D FSG 2 Class 9013 Series B pressure switch, Franklin Electric #280-1070-101 3/4 HP 230v 60hz 1-phase 3450rpm Control Box. I believe the pump/well is about 300 feet deep. House and well built in 1977. I noticed a week ago that pump kicked on when no water was being used. Noticed it only that one time and it kicked on/off 3 or 4 times. A few days ago, had very low pressure all over the house. This low pressure started just after a bad electrical storm. The gauge on the tank showed 0 psi (for real!)and the pump is not running at all. I turned off circuit breaker, then heard all water in the pipes (including water heater) flow back into the pressure tank. When I turned CB back on, it still showed 0 pressure on the gauge, but after a while started getting a little water coming into any faucet/shower. Today, there is no water at all. Turned off CB again and again heard all the water flowing back into the pressure tank. CB is back on. Still have no pressure on gauge. The pump is still NOT coming on. There is NO shut-off valve between the well and the tank.

Does this sound like a simple fix (turn power off and replace Square D pressure switch and clean out the nipple to it?, replace control box?). Even if not simple, I would like to have enough info so the serviceman doesn't rip me off. I have a high-quality Fluke multi-meter on hand and am generally good at fixing things. Thanks very much for any help.

With the multi-meter you can check and see if it is closing and providing power.

I not familar with submerged pumps so I am not sure what is in the control box. But I know that some pumps have external starting capacitor. A clamp on ampmeter would probably tell a low about what is happening.

But from what you describe and without anyother testing I am suspecting that you don't have an pump problem, but a plumbing problem. That the pipe from the pump to the pressure tank is cracked. Either in the well or the part from the well to the house.

Thanks, Billhart for replying. When you say "see if it is closing", do you mean the pressure switch or something in the control box, or both? I don't have am amp clamp right now, but can get one. I would put that on between the switch and control box? Eek! I hope it isn't a cracked pipe. Or you saying that if a pipe is cracked, the system senses this and does not turn the pump on. Also, doesn't it seem abnormal for there to NOT be a visible shut-off valve anywhere in the basement with pipe and controls or outside the house? Thanks again. I really do appreciate someone caring!

You keep saying that the pump is not running, but how do you know.

" Or you saying that if a pipe is cracked, the system senses this and does not turn the pump on."

No, I am saying that if there is crack in the line the pump will just be pumping water into the ground or circulating it in the well.

And you indication that you got some slight pressure, but when you turned off the breakers you heard water running hints to me that pump was running, but not able to produce much (or any) pressure in the line as it was leaking someplace.

"Also, doesn't it seem abnormal for there to NOT be a visible shut-off valve anywhere in the basement with pipe and controls or outside the house?"

I would think so, but I really don't know.

"Thanks, Billhart for replying. When you say "see if it is closing", do you mean the pressure switch"

Yes, the pressure switch is the first step.

You should have 240 volts on the two hot lines from the switch to the control box.

Now I could not find any information on the control box # that you listed, but I supsect that this one is similar.

http://www.franklin-electric.com/Manual/AIM_49.htm

Either one of the top 2.

And here is some testing that you can do.

http://www.franklin-electric.com/Manual/AIM_44.htm

No a failure of the start cap or the potential relay can either one prevent the pump from running. And they, specially the cap, could be damaged by a surge.

But as I said a "dead" pump does not match the symptoms that you gave.

And it is continued onto the next page.

There might be other usefull information in that manual. I just jumped into likely spot.

I believe the pump is not running because I could always hear it kick on/run/kick off when I was in the bathroom above the pressure tank. Been here 18+ years and it always kicked on about the time I got out of the shower or when doing laundry in basement and hot water tank was refilling. Or was I hearing the pressure tank????? Thanks much for your insight on a leak and the other stuff. You really sound like you know this stuff. I'm heading down there with the meter as soon as I check the Franklin sites you sent. You're right about the model #, couldn't find it on my own. Guess it's too old...

Most likely what you where hearing was the pressure switch snapping on. There might be some noise from the relay in the control box, but have no idea how much.

With zero pressure that has already snapped and it won't go the other way until the system builds up enough pressure to shut it off. Typical pressure switches are 40 psi on/ 60 off or 30/50.

Yes you have a hole or other leak in the plumbing from the pressure tank back to the pump. The pump has been runing constantly, and the switch won't be clicking closed and open. The pump will have to be tested electrically and for its ability to pump but there will be a broken/cracked fitting or a hole/split in the plumbing allowing water to spray into the well instead of coming up to the pressure tank. The leak could be underground between the well and the house too but more likely it's in the well.
