By HPP i think you're referring to the WATER PUMP PRESSURE CONTROL SWITCH - discussed at https://inspectapedia.com/water/Water_Pump_Pressure_Switch.php

where you'll find a series of diagnostics.

my Hpp is working manually when contactor is pressed on the board

On 2019-01-29 by (mod) - can't get the pressure switch to respond to drop in water pressure

I would replace the pressure control switch AND the tubing or pipe that conducts water pressure to the switch.

OR first, with water on and the pump not turning on when it should, try tapping on the pressure control switch box exterior.'
I tried, no hope!!!

On 2019-01-23 by (mod) - Monsoon 2.0 bar single pump won't start

Check or replace the pressure control switch and the tubing that conducts water pressure to the switch sensor port. Debris clogging can cause the switch to fail to respond to a drop in water pressure.

Occasionally (every other day) my Monsoon 2.0 bar single pump won't start when I turn on the shower hot water tap. When the pump doesn't start, there is hot water that comes out (from the cylinder tank), water out free flowing.

Sometime the pump works perfectly, kicks on within seconds as I turned the hot water shower on.

Any ideas?? Can you please advise? Thanks

Got an onga water pump on top of rainwater tank, to house. Pump keeps cutting out. Press the reset button and it works for a while, then cuts out again .....

On 2019-01-13 by (mod) - pump tank combo starts and stops intermittently

Jose

I HATE HATE to claim a "double fault" as usually it's just one problem, but this sounds like two different issues.

If the pump starts when no water is being run in the building see the diagnostics at WATER PUMP INTERMITTENT CYCLING https://inspectapedia.com/water/Intermittent-Water-Pump-Cycling.php

Usually there's a leak somewhere in the building or outside or in the well - such as at a check valve or foot valve.

But when the pump turns off quickly I suspect your pressure tank may be waterlogged - needs air.

That issue is explained at WATER PUMP SHORT CYCLING - home

My tank pump combo is running intermitently. It starts , increases pressure then turns off immediately. Checked the air pressure in the tank and had no pressure at all. How can I fix this? No frozen winters here in PR.

On 2019-01-09 by (mod) - pump impeller or motor shaft is seized.

Anon

Sorry to say it sounds as if the impeller or motor shaft is seized. If rotating parts are frozen it's time for a new pump.

On 2018-12-17 by (mod) - bad washing machine solenoid valve?

Pressure booster pump for washign machine (C) InspectApedia.comNaga

This sounds strange indeed. I suspect that the washing machine valve is not permitting any water to enter the washer - else the pressure would drop and the pump would turn on.

Give us the pump brand and model and the washing machine brand and model and perhaps we can review and find an answer in their specifications.

Hi,
I have connected a auto booster pump to my tap outlet and connected the booster pump out to the washing machine , but unfortunatly the pump won't start when washing machine demands/opens valve for a water.

But the pumps works perfectly when working with open tap on/OFF automatically when washing machine is not connected. Let me know is there any solution to fix this ?

I have a new irrigation system pump connected to a Rain Bird System. I recently repaired a leak and put the Rain Bird to manual mode to check for leaks at the repair. However, the pump will not turn on and all I hear is one click ?

On 2018-11-21 by Edith Hendrickson

Pump is getting electric and won't turn on had the pump tested they said it was working

On 2018-11-06 by (mod) - spark at the pump capacitor

Sounds like a wiring error, a shorted relay, or a dead well pump.

On 2018-11-06 by Duane Phillips

I recently had a problem where i just heard a hum when i switched on so i changed the capacitor then when it switched on I saw a spark by the capacitor now no noise and it doesn't run
