Negative Head Pump - very hot

kelbal

Hi guys, the water pressure is very low in my friends apartment, and the negative head pump is scalding hot to the touch, so it looks like its faulty.

I've heard that replacing the circuit board can fix alot of issues, is this the case?
Or else just open up the pump and manually rotate the blades to potentially clear any blockages?

I've installed my own pump in my house, but haven't done any maintenance, I presume this stuff I've mentioned is reasonably straight forward?

thanks

Its all fun and game fixing your mates pump till things go tits up and he rings you saying it leaked and destroyed his apartment and the one below as well I have seen this happen

The windings are gone in the motor. Pump needs to be replaced.

No, individual parts fix the individual problems.

There is no requirement to open the pump to rotate the motor.
Anyway in this case the motor is shot.

To add to Anthonyos' comment,
If you are not familiar with them and not equiped properly you could potentially do some serious damage to people's property.
If you are thinking of fitting a pump in your friends house the least you should have is public liability insurance.

Thanks guys - just went ahead and installed a new pump. Expensive, but not worth the hassle of messing around with the dodgy one and the potential disasters that it might bring on.
