Pump seems to start & runs but when pressure gets to about 20lb. I think it trips out on the internal over loads? Its a 1 hp. 230V (3-wire) has proper starter control replaced it new 3 years ago (pump & control) I have 240V at the pressure switch & on the line side of the pump control. Its a Water Ace brand pump model R302A if this pump is shot can anyone suggest an good brand? I would like to get more than 3 years use out of one, Thanks Dave F.

mabe your tank is water logged.is it a bladder tank?if so check by closing valve before tank,then turn cold faucet on & drain tank,next put no more than 26lbs air in tank.this will get you by for a few days and give you time to change tank.go for at least 80 gal.120 gal.is best for home use.
if not a bladder tank check snifter valve(looks like a tire valve)on check valve before tank. unsrew cap if it has one.bubble of water on top should be sucked in when pump shuts off.could be this is only problem.next look at pressure relief valve on side of tank.this is too pass off excess air buildup.if bad you will notice air comming out faucet. if it is the motor replace only the motor.pump should be ok.some well men love to replace the whole unit at several times the price of just the motor.hope this helps,hard to diagnose long distance.

The thing that looks like a tire valve should not have a cap on it. Also, if you replace it, do not replace it with a regular tire valve core. It is not the same thing. You will have to go to a pump shop to get the proper core. That valve is there to allow air to flow back into the system and keep things from getting waterlogged.

Exactly... thought someone may have put a cap on not knowing

A guy I work with has iron alge problem his pump would only get to 26 lbs cause the alge was blocking it plugging it up he just had it replaced and the well treated with clorine his only last a few years.

Also, check your voltage on the downstream side of the pressure switch with the pump on and running. I've seem the contacts mess with peoples minds really bad because they conduct just fine and show 110 - 120 on each leg. But when the pump kicks on or starts to pressure up one leg drops to nothing becuase of a bad contact.
Checking the amperage on each leg is the true test of the pump once you make sure you can send the current/voltage to it.

If the pump comes on, you could probably rule out the starting relay and starting capacitor. I would still lean towards the pressure switch and contacts.

Let us know what you find.

Some good pumps are.

Grudfos
Goulds
Red Jacket
Aermotor

I have a Grudfos. It works good.

The first thing you need to check is current draw. See if you can get ahold of a clamp meter that will clamp over the outside of one wire. Only check one wire at a time. Clamp the meter on the wire and check the current. The original literature on the pump should give you current draw spechs. If the current draw is OK then check the pressure switch. It may be shot, especially if you did not replace it when you replaced the pump. I would think the pressure switch is probably the culprit if it always kicks out at 20 lbs. One more thing you might check is the pressure gauge. It may be reading light. It may also have water in the tube that the gauge is set on. If water gets against the gauge, it will try to read the water pressure instead of air pressure in a column, and water is not compressible hence the low reading. Good luck on your pump. Hope it is something simple and inexpensive.
