20 Most Recent Flotec Corrosion Resistant Shallow Well Jet Pump 1/2HP, 8GPM Questions & Answers

These holding tanks are pre charged with air which in turn pressurizes the water. The tank has a bladder and an air valve on top. The pre charge ,over time, loses pressure, and the tank has to be pressurized again.

• The well pump needs to be turned off.
• The water has to be drained from the tank
• Air is put into the tank from the air valve on top of the tank, and is measured with a tire air gauge.
• The pre charge pressure is set to two psi below the pump cut in pressure.
• In other words if your pump kicks on at 30 psi, the pre charge pressure is set at 28 psi. If the pump kicks in at 20 psi, the pre charge is set at 18psi, etc.
• After you pressurize the tank, turn water back on.
• If water comes out of air valve on top of tank, then the bladder is ruptured and you need a new tank.
• Hope this helps!

You need to purchase a new pump. Attempting to repair this will only cost you time, money, frustration and a new pump in the end.

https://inspectapedia.com/water/Water_Ace_Pump_Manual.pdf Add Comment if this is not the manual. Your question is posed under Flotec Corrosion Resistant Shallow Well Jet Pump, but you requested a manual for ACE51 pump. http://www.wellpumpsystem.com/tags/ace5s/

If in the past your system can build-up pressure up to 40 psi even if the supply valve is open and water is being used in your house, then your pump impeller maybe already worn out that's why its pumping capacity was reduced.

Check auto stores for a manual that shows the resistor. You can always Google it, too.

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

Put a vacuum gauge into the front drain plug port with the pump installed and see how much vacuum it draws. If it is low get the pump or lines repaired, if not have a well driller check the well point.

The wiring information is in the manual. Are you calling the pressure switch a safety switch?

Check for power to the pump then check again after the built in pressure switch. You can get the manual from Flotec at: http://www.flotecpump.com/ResidentialResourcePage_resourcepage_ownersmanuals.aspx If the motor buzzes then there is probably a bad start capacitor.

Jet pumps are inherently noisy, has it always been this loud? Loud is a subjective measurement and varies from person to person.

how deep is the well can you hear the pump working.or are you able to pull the pump up to inspect it.or can you place ahose down the well to be sure that water is down there,some pumps have a pressure sensor so when theres no water it switches of so as it does not opperate dry,because this will damage the seals in the pump,hoe this helps.

It may be normal, pumps make noise.

Hi,
Those pumps will reach 50# when brand new, but soon the parts wear and then they will not make that pressure anymore...
Instead of replaceing the pump, just back the pressure down a tick or two to get it to shut off and not waste your electric....

Try cleaning the jet.

Hi,
You either have an air leak or you have a foot/check vlave problem that is just letting all the water run through and not allowing you to prime... these can be very difficult to prime even in the best conditions...
Yes, you could melt the impeller, but probably not... they are very hard to get enough of a grip on to get hem off... I have destroyed many and just replaced them with new after I got them off...

Check your pressure switch. Possibly stu

The sand point at the bottom of your well pipe has a screen designed to keep sand out of your water system. This screen has probably failed and that is where the sand is coming from.Unfortunatly this is not an easy fix. The well needs to be pulled and the sand point replaced.

Look for a place in the pipe from the pump to the house where an air pocket could form. That will fool the pump.
