You should have a check valve installed on the incoming water line ( suction line) of the pump. This should keep the water from leavin the pump. if you still need to prime then there is a leak on the incoming line from the ground to the pump and you will need to have a well company come out and install a new line.

If water is back up above the intake, it should prime itself in a few minutes. As long as you don't let the case get hot to the touch it should be okay to run dry.

If it fails to prime and pump up pressure, you may have to prime it.

Pump does not pump anything. motor is running and getting hot, no water being pumped. i have to prime this stupid thing?


If you are trying to draw water from a lower place, you may have lost prime. It is also possible there is a reason for this loss of prime, maybe a leak on the suction piping. Remove some fitting on or near the discharge of the pump, fill the body completely with water. If it goes in, fill the entire suction piping with water, too. Open a faucet nearby, turn on the pump and wait up to 5 minutes. It should spit and sputter, sound will change, some water will discharge, but eventually, you should get steady flow.
If you lose prime again, look for leaks in the suction piping from the inlet of the pump to where the piping goes into the ground.

You can't prime the pump with the same water source you are trying to build pressure in. Shut off all the water going to the house, use the neighbors hose or have several gallons (maybe 5) to prime the pump and continue priming pump until it starts to build head pressure then plug prime hole.

Had to replace shallow well pump. Bought jet pump (used to have centrifugal pump), and installed it. Had to replace inline check valve, losing well prime. Priming pump does not accomplish the job. ...


Hi,
Aj, do you have a foot valve on the bottom of the pipe in the well?? The jet pump needs to have a foot valve to hold the water in while priming it... you also have to carefully design the system and prime it in such a way as to eliminate all of the air in the piping. A jet pump will not pull the water and expel the air like a centrifugal pump will...

I think the part you are missing is the foot valve...

The water and therefore the pressure has to be going somewhere. If you are sure that there are no leaks in the house or outside, then the water is going back into the well. There is a check valve either in the suction line of the pump between the top of the well and the pump or down in the well.
If this check valve fails, it allows water to go the wrong way and back to the well. The result is that you lose pressure.
Secondly, you have to be sure that there are no air leaks between the top of the well and the inlet to the check valve. Leaks in that piping will make repriming difficult.

Pump will not pump water, its runs


Hi and welcome to FixYa. I am Kelly.

If this is a new system installation there can be a few reasons for the pump not pumping water.
1. The most porbable cause is that it is sucking air on the suction line. Check to make sure each and every connection it a good sealed connection.
2. The pump having never had water in it may have to be primed by introducing water into the outlet hole or remove the impeller housing plug and prefill the cavity with water.
3. There should be a check valve or a foot valve with screen at the very end of the suction tube.

Limitations
Jet pumps lose efficiency as the total lift increases. Total lift includes the vertical distance from the water to the pump plus the friction losses in the suction line and foot valve. Shallow well jets are not practical if the total lift exceeds 5.5 m (18 ft).

Pumping water containing sand will cause wear and leakage around mechanical seals. The mechanical seal on the pump shaft is water lubricated and water cooled, so the pump should never be run without the pump casing being filled with water. Air or gases in the pump will cause a loss of prime. Shallow well jet pumps must have either a check valve or foot valve installed on the suction line to maintain prime.

Foot Valve:

Check Valve:

You can use both if necessary but usually only one is required. The in-line check valve can be closer to the pump.

I will post troubleshooting if the site will accept the steps next post. Currently it says I have exceeded maximum length.

Thanks for choosing FixYa.

My Stay Rite Pump 1 hp, 230 volt model DS3HE - 01 runs, but does not operate my irrigation system with any pressure. I resume the pump has lost its prime, but have no clue as to what I might do to fix it?


pumps lose prime for a few reasons...bad foot/check valve, crack in the suction line are probably the two most common.. see if there is a threaded fitting( most pros put one on the pipe some where) on the top feed of the pump. open it up and add water til the pump fills up. if the pump is outside turn the pump on before resealing the fitting, otherwise resael the fitting and open a spicket outside. depending on your water table it could take some time to prime but in normal circumstances up to 20 minsif it does not prime you may want to consider hiring a pro!!

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.
