Question about Heating & Cooling

1 Answer

I have a 1/2 hp jet pump that draws lake water. We have tried and tried to prime it and get it up to presure. I have replaced the foot value but when started it reaches 20 psi and waivers down to 5 then back - can't seem to get it truly sucking. We have filled pump with water, replaced the plug loosely, let air bubbles escape and repeated literally dozens of times. The feed line in on a gradual slope up from the lake. Any further suggestions?

I have seen little critters (looks like baby clams) make a home inside the suction pipe and on the impeller in the pump. They can cause a lot of pressure problems with just a few of them in the way.

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.

HOW can I tell if a Goulds jet pump needs replacement?


pull the foot valve as it takes very little to allow the water to drain back out. Personally I would replace all pipes in the hole with heavy duty /high pressure plastic agricultural irrigation pipes

Not enough suction


It sounds like it is a jet pump in a deep well. You probably will have to pull the foot valve and clean or replace it. Because of cost I would suggest getting a qualified repair person to check it out.

Will not prime


My pump didn't pump until I filled the 'suction side' pipe with water before I attached the pipe to the pump. The suction pipe needs a foot valve if you have a long lift from the water to the pump. Then pour water into the pump on the outflow side. Should pump fine . It'll purge the air out after a little bit if you filled the pump with enough water. I almost bought a relacement pump but then realized that the foot valve wasn't sealing and the suction pipe wasn't holding water. We have about a 8 foot vertical draw to the pump . Good luck.

Pump will not prime.


Pump self primes after the housing is initially filled with water. Failure to do this will reslut in the unit not drawing up the water and could potentionaly damage the unit.

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...

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.

I have a Jacuzzi Jet Pump Model 7C-S/B. Not Working


Check the breaker that supplies power to the unit. If it is in tripped position, check if the motor is grounded ( continuity between terminals and motor body), check for shorted windings (infinity resistance value between the winding phases), and finally check if the pump is stuck up due to debris or defective motor or pump bearings.

New 1/2 hp jet pump with tank not working


Your hose size is to small. Use a 2in black plastic line out to the lake. Inspect your foot valve, and
take your pump apart to see if you may have a pebble stuck in it, and remove the inner workings
and clean. Contaminates build up inside and need to be flushed out. Remember to replace the
gasket. Tighten all your hose clamps. Once your ready to start, spray shaving cream on your
fittings to see if your sucking air. I've been through it all and my pump works fine.
