Replace the pressure control switch as the problem indicates the non-return valve is leaking back and not holding pressure

SOURCE: Flotec Shallow Well Jet Pump won't pump water

The tank is an air tank, it works like a cushon and accumulator.

Have you reconnceted the pump? If not fill the pipe that goes to the well with water. It should not drain down, there should be a foot valve that prevents the water from running back into the well. So if the foot valve is working it should not take a lot of water to do this.

Pour water into the suction side of the pump until the pump is as full as you can get it, reconnect the pump and start it up. Yes it does need to be primed

Good luck

SOURCE: i have a flotec water pump that sits on top of my

if the pump is working correctly, it can either be, need more water to prime it, or something in the well, such as low water, plugged filter, etc....sometimes when you have a system that is intermittently used, it can take 20 or 30 minutes of continuous priming to get it to pull, enough water to maintain the prime.

SOURCE: Well pump not shutting off and tank never reaching full pressure

50 years old isn't bad..... but technology has changed a bit. I do have a few ideas. I'll list out several problems/solutions, and you'll have to pick and choose, depending on your particular circumstances. It will be a long read, but I would suggest that you read to the end before picking a course of action. Hopefully, others will offer advice as well.
Make sure that you have a working pressure gauge. I only say this as all of your (and my) assumptions have and will be made off of the gauge. It's critical. OK, with a working pressure gauge....Are we seeing the same pressure? If the pressure is actually higher, say, in the range that you are regulating for, or higher, the pressure switch is suspect and should be investigated/replaced.
When you shut off the pump, does the water pressure fall off? If it does, this might indicate a leak either internally (well/pump) or externally (faucet, etc.). Locate the regulator on the side of the pump. With the pump running (and a good pressure gauge), turn the regulator adjustment several flats, rembering your original position. This is best done with the pump at max pressure. Operate it in both directions, say four flats one direction, back the same to the original position, then 4 in the opposite direction, and back to the original position. Note the pressure on the gauge each time you make an adjustment. If any improvements are noted, work with it.
The most common problem with pumps not putting out enough water usually isn't the pump, but the well itself. Most wells have a foot valve and jet valve assembly. The foot valve has sealing rings on them known as leathers (although these can be made out of other materials). If the well is shallow, say 20 feet or less, the pump will normally pick up water without too much difficulty, even if it won't maintain pressure at the tank. Not knowing the depth of your well and the age of your equipment makes it a little harder to diagnose. Slippage within the pump, allowing some of the water to spill back, is a possibility, but you would expect the pump case to heat up over time, and this doesn't sound like the case. My guess is that you have some leak-by in either the jet assembly or the leathers, allowing some of the water to leak back to the well. The foot valve would keep the water pressure from dropping to zero. I'd trip the breaker to the pump motor and break the well head away from the pump (leaving the cast iron piece on the inner pipe). You should have a triangular piece around the outer well casing. Loosen the three bolts, then remove the two bolts that hold the pump to the well head. Gently separate the two, and set your pump off to the side. The aim with "gently" is to avoid tearing the gasket. (If it does tear, you can purchase gasket material and hammer one out, if replacement gaskets aren't readily available). Once the pump is removed, you can remove the inner casing to which your jet and foot valves are attached. Careful when removing it,though. You do not want the inner casing to unscrew from the well head and fall down the well. If there is a lot of sediment in the well, it will be more difficult to remove the inner casing, as the leathers press against the outer casing making the seal. I have always put several gallons of bleach down the well, although recently, a neighbor had muratic acid put down his well. This is dangerous, however, and only trained and skilled personnel should attempt. I let the bleach sit for several hours, allowing time for the bleach to soften the leathers. Once done, extract the inner casing, pulling the well head, inner casing, jet valve and foot valve as a unit. You'll have to pull it in a big arc and lay it out slowly as you go. More hands are better for this task. You may need to get creative in supporting the line it it's PVC. Once extracted, visually inspect the lower components. I recently saw one with a hole eaten in the top of the jet valve, producing similar results to your issue, but worse. Anyway, if this is where you are at, I would, at the very least, replace the leathers. And, I'd double them. Truth is, when I go to that much effort, I replace everything at the bottom of the well, foot valve, jet valve, leathers....
We havent hit on the tank yet. Older systems had an air injection system where a shot of air was injected every time the pump cycled. If no air went into the tank, the tank would become "waterlogged" over time, and would cycle constantly. This system was prone to failure. The remedy for this was to drain the tank, and start over, and to replace the air injection system. This usually called for the pump to have to be reprimed as well, at least at my house... Newer tanks have bladders in them with a pressure set on them to provide the same air cushion that the older systems provided. The air pressure on mine is set to 28# via a schraeder (bicycle tube) valve at the top of the tank. Check yours if so equipped.
Well, that's about it for now. Make your checks and please let me know what you turn up. I'll check back.
Best regards and good luck,

SOURCE: Problem with Convertible Jet Pump 3/4HP RedLion -

If I understand you correctly this is what you have:

- A pump that draws water from a lake 300 feet from lake to your cabin (I assume the pump is at the cabin)

- The pump kicks on to maintain pressure in a tank that distributes water to faucets in the cabin. The pump only turns on to pressurize the tank when water is being used (I am assuming).

- When you turn on tap, pressure in the pressure tank drops to 30 psi, then you hear water sucking from the tank to tap and flow stops at tap. Then the pump finally kicks back on and pressures tank to 23 psi.

- The pump is not used regularly.

If water flow stops when the pressure tank is reading 25 psi, then likely the real pressure is 0 psi and pressure gauge is reading wrong. If this gauge is tied into a switch that starts and stops the pump, then this is probably your problem. You may have partial blockage in your pressure gauge/switch that is causing gauge to move too slowly to keep up with the actual pressure changes when water is being used. Ore the pressure gauge/switch may be broken. Pressure gauges are notorious for reading pressure when there is none. If you can unplug the pump and disconnect the pressure gauge/switch and check for blockage in the ports you should start there. You mentioned that this worked good for the last two summers, if if sits unused for long periods, it could promote bio-growth, rust and/or sediment in the connection to the pressure gauge. If you find blockage, remove it and flush it out. Reinstall the pressure gauge/switch and try it again.

One other possibility is clogged strainer(s) / filter(s) in the water lines. It would not hurt to pull and check/clean any strainers / filters in the system including before the pump. I would even check at the lake for a strainer where the water enters the suction line to the cabin.


I would not assume that the pump is the problem yet.

Hope this helps.

Davey dual tank /town water pump. When water is used the pump starts and massive gush of water comes from the bottom of the pressure control unit wasting lots of water a plumber told need new system.


That is not a pressure control valve, that is a back flow preventer that is seating and there is nothing that you can do about it.

Can you adjust the pressure setting on a Davey Torrium T45 pump to reduce the power of water when taps are turned on?


No. The pressure can only be adjusted at the expansion tank and pressure switch. Keep in mind that your tank pressure needs to be 2 lbs lower than your cut-in pressure. The pressure in your tank can be bled off at the schrader valve(tire valve) at the top of the tank. You MUST adjust both the tank AND the press switch.

Davey presssure pump when switched on b4 tap is opened the pump does run stop run stop run stop between each cycle small squirt of water escapes from pressure tank at the clamped junction


fix the leak as the pump build pressure switches off , the leak looses pressure pump switches on and so on
fix the leak and the pump will build pressure and switch off until the tap is used

How do I stop pump from running? Cistern connected pump does not seem to be pressurizing. Pump not cutting off, and getting hot.


Pump probably needs to be serviced. It probably pressurizes a tank and when that tank reaches a pressure the pump is turned off. But just guessing.

Davey pressure pump will not run, was running fine last night


You checked the power supply and it works, you may have to take it aprt to clean the magnegtic inters or replace the inters or pump because broken shaft, trash gets in them and stops the rotation of the pump blades. But really need more info on the pump.

Our auto irrigation system wouldn't turn off. We found the Davey XJ70 pressure pump was leaking so replaced the leaking pipe. Now the watering g system won't start. What do we do?


Hi Geralidine
Sounds like your pump is "air bound"...meaning that the impeller housing of the pump is full of air, and it cannot pump water.
Try bleeding the air out of the pump and put a positive pressure (garden hose pressure) and make sure that you shut the airbleed valve off after you start to pump.

I have an old davey xp350p water pump connected to my water tanks and would like to know how much pressure should be in the bladder as it goes on and off rapidly all the time. thanks


The tanks useally come with the pressure set in them, if you messed with yours call a place where they sell em and give you size and model and they will tell you,,,,also if the little tag that comes on the tank is still there it says right on the tag,,,Another thing that pump has a control to ajust the water pressure all water pressure to a home should be at 50lb,s look at you gage and see if it is going off at 50lb if not it might be the proplem,the little box with adjusting spring in it.I have seen these go bad.

Our water pressure in our house is gone. we have a well. do you think the well is out of water? do we just need to wait till it rains?


If you did manage to run enough water to dry the well, it should only be temporary, until enough groundwater flows back to your well. This should only take maybe an hour and shouldn't depend on frequent rain. If your well did respond to rain, your well would be quickly contaminated. However, there could be other problems. If you have the type of well where the pump is located down in the ground, and your water pressure doesn't come back soon, then you have a problem in that the pump is not working. If you have a "shallow well" type of pump, where the pump is located above ground (in your basement, or under the house) then the pump may have lost it's prime. A shallow-well pump needs the pump to be full of water before it can pump the water from the well.
