I think you have a air leak. Please recheck all the fittings including the pressure line and the gage.

Let me know if this helps.

How do I prime my flotec 4022 pump


A number of Flotec pump manuals are available here: http://www.flotecpump.com/ResidentialResourcePage_resourcepage_ownersmanuals.aspx . The site lists a FP4022-10 pump with the direct link to the manual here: http://www.flotecpump.com/resources/images/514.pdf .

For this type of pump, there should be a priming plug or priming tee. Remove the plug (or tee) and pour water into the pump. Keep adding water until the pump and all of the piping to the well is full of water. If a priming plug or tee was also added on the suction side of the pump, open that section and fill all of the piping on the suction side with water. Replace the plugs/tees then open a faucet in the house. Start the pump. After 2-3 minutes, turn off the pump if no water has come through the unit. Add more water through the priming plug or tee (or multiple plugs and tees). Then repeat closing the priming ports and start the pump after opening a faucet. Once the pump is actually pumping water, turn off the open faucet. Wait for the pump to shut off once it reaches full pressure. Open one or two faucets to check that the pump is properly sensing the pressure changes and maintaining system water pressure.

If the unit didn't pull water from the well, check the piping for air leaks. See the full trouble-shooting guide in the manual. Page 9 has the priming information and page 10 has the trouble-shooting guide.

I hope this helps.

Jet Well Pump Well Jet Water Pump


One of the most frustrating things in plumbing can be the priming of a jet well pump. Well jet water pumps are sometimes difficult to get working properly because it is very difficult to get all of the air out of the system and the pump. Well domestic water systems are great for those that need them but you need to know how to approach the air removal part.

Here are some things that will help you prime both deep well jet pumps and shallow well jet pumps.

  1. Always install a tee and a valve at a high point directly above the outlet of the pump. This will give you a place to pour water in and allow the air to get out easily.
  2. Always install a “throttling” valve on the “out” side of the pump. This will let you keep back pressure on the pump. This is especially needed for deep well applications.
  3. Install a switch close to the pump to make starting and stopping the pump easy.
  4. Make sure that the “suction” pipe coming to the pump runs continuously uphill and is not trapped anywhere.
  5. Make sure that the suction pipe is at least as large as the intake fitting on the pump.
  6. Make sure that all fittings on the suction pipe are air tight

To prime the pump begin by filling the pump and suction pipe slowly with water, allowing the air to escape as you fill. This may take quite a bit of water depending on the size and length of the pipe.
When you can get no more water to go in the pipe, then close the valve on the fill and start the pump with the “out valve” closed or mostly closed. If the pump starts to go on and off rapidly, open the out valve just a bit more, till the pumps runs continuously.
If the pump starts to pump and then stops because of an air pocket, then you may need to restart the whole procedure and add more water. Keep doing this till all of the air is worked out of the system. For some systems this can be a long and laborious procedure.
Keep working the procedure and eventually you will have your system pumping.

I have a utilitech 1 hr convertible jet pump. My well is 58 feet. My foot valve is at 68 feet. My pump is primed. But it still won't pump water. And it us set up for deep well. Any suggestions?


I think you mean your well is 68 feet and your foot valve is at 58 feet. To properly prime a deep well jet system you must completely fill not only the pump but the entire casing also. This should take about 5 gallons of water. If you are not using anywhere near that much water to prime it may be the well casing is air locked which means the air in the well has no place to go and won't allow water in if there is a plug on top of the well adapter remove it and then try to prime system. Another method is to run the pump while priming to help break the airlock. Hope this helps.

Any suggestions when a newly installed utilitech pump won't turn off?


its sucking dry or your wiring is not right, or of course an airleak, or the prime is not good, did you fill the pump prime hole at the 3/4 plug on bottom.of pump, deep well pump do you mean submersible? if so and it is a deep well submersible there is a prime, its got to be an airleak in the line or the pressure tank is not pressured up to the specs, and the gauge

PRIME A GOULD PUMP


whats your question how to prime the pump? if so at the bottom is a 3/4 inch plug screwed into it, or at top, once the pump is hooked up to the lines turn off the power, and unscrew the prime plug fill with water, then screw in tight DO NOT USE THREAD SEALANT THEN THROW THE POWER TO THE PUMP, of course house supply valve must be off 3/4 turn valve off until the line is primed then open the supply line to house slowly to supply the water to all the lines, NOTE WHEN YOU FIRST INSTALL A NEW PUMP, HAS TO BE PRIMED, HAVE TO HAVE SUPPLY LINES FROM WELL TO HOUSE CLOSED TO PRESSURE THE TANK AND TO FILL THE LINES.

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.
http://www1.agric.gov.ab.ca/$department/deptdocs.nsf/all/agdex1143
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:
http://t3.gstatic.com/images?q=tbn:21SLW7C9NsXXdM:http://ecx.images-amazon.com/images/I/518Frco3KaL._SL500_AA300_.jpg

Check Valve:
http://t3.gstatic.com/images?q=tbn:xIVfmPrrsgzS-M:http://www.plumbersurplus.com/images/prod/1/577733-BCV-1-L.jpg

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.

Have installed a 1/2 HP wayne jet pump, getting water ,


If we go down the list of possible causes, it may help;
  • All fitting on the new pump and jet are tight.
  • No break in the well line
  • FOOT valve operating OK. If the foot valve is not operating correctly, the pump can lose its prime and **** air into the system.
  • New pump has been purged of air(primed adequately)
  • holding tank has appropriate pre charge
  • bladder in holding tank not ruptured.

Jet pump does not pump water


I had a similar problem and as a last resort took the pump apart and cleaned it and the jet. It's a very old pump but works ok now.
