Banging Noise at the Water Pump - Q&A

Water Pump makes Banging Noise and the pressure gauge is going crazy

When the water pump comes on before it shuts off it is making banging noise and the pressure gauge is going crazy On 2018-04-28 by Jean legault

by (mod) - water pump making banging noise

Usually this is a water hammer problem described at WATER HAMMER NOISE DIAGNOSE & CURE

Occasionally I have traced a water or well pump banging noise problem to is a blockage on the pump outlet side, like a clogged water filter or a closed valve, or the pump's CUT OFF pressure is too close to the maximum pressure that the pump can achieve. Try setting the CUT OUT pressure down slightly.

Water pump causes a hammering noise when it shuts off - do I need a new check valve in the well?

I just had a new well pump installed in my crawlspace about 2 months ago. I noticed right away it is louder and seems to run more often than the old one.

Now it has developed pipe hammering when it shuts off, which is gradually getting worse.The guy who put in the pump says I now need a new check valve in the well, at a cost of $1800 dollars! On 2018-01-09 by Lori

by (mod) - better cure for water pump - pipe hammering noise

Water hammer is usually solved above ground by a water hammer arrester.

Read WATER HAMMER NOISE DIAGNOSE & CURE and you'll see an easy repair to try - at a fraction of the amount you were just quoted.

Watch out: However if the foot valve in your well failed, that could explain why the previous pump burned-up or failed as well as explaining frequent well pump cycling or even loss of prime.

Installing the new pump itself would not have been the cause of that original foot valve failure, more it is the symptom. Sorry. We might wish the installer had diagnosed that problem and fixed it when the pump went in.

Water Pump makes a ticking noise

Why does our water pump make a ticking noise ? On 2018-04-22 by Meme

by (mod) - is the noise from the pump or the switch?

It would be useful to know if the noise you describe is actually coming from the pump or from the pressure control switch.

In that case, see CLICKING WATER PUMP Q&A

If the noises from the pump is the noise occurring when the pump is running, or after it is turned off.

If it's the latter I suspect maybe the motor is overheating and you hearing a cooling down thermal contraction noise.

What's causes a water pump or irrigation system to howl?

I'm watching my bosses house and out by the grape vines there is a irragation box that has been making a very loud howling noise for hours not sure what to do On 2018-04-21 by Sandy

Answer by (mod) - cause of howling noise at the pump, goes on for hours

That sounds like an irrigation pump that is not working - look for a switch to turn it off, or go to the electrical panel and one by one, flip off circuit breakers until the pump stops.

I suspect a bad pump bearing.

For other possible causes, see

HOWLING NOISES in BUILDINGS 

Loud POP from the well pump control box and circuit breakers trip

Replaced both pressure switch and control box, everytime i go to flip the breaker to turn everything on you can hear water start to move then theres a loud pop from the box and the breaker blows, side note someone wiggled a wire before i changed the box and water worked for about 30mins On 2018-04-08 by Nick

by (mod) - short circuit or circuit overloaded or seized pump motor or switch relay.

Check the wiring, that sounds like a short circuit in the wiring, a wiring error, or else a seized motor or a pressure switch relay that has welded into the "closed" position.

The "POP" can be arcing at a switch or you may be hearing a circuit breaker trip.

Watch out: leave electrical power off and call for repair from a licensed electrician.

by nick

All the wires on house side going to pump or switch are correctly put in, put back into same places when replaced, and everything ran great till a week ago when all this started, could it be something else?

by (mod) - pump trips circuit breaker - does the pump hum?

A short circuit anywhere in the wiring circuit OR a pump motor that's seized or an electrical control that's wet or under water or has failed could explain a sudden trip of the circuit breaker when you turn power to the pump back on.

Depending on the circuit breaker brand there could also be a bad breaker (such as FPE or FP).
