Hi everyone,

First time poster (please be gentle).

Generally handy chap in need of a little more expertise, if possible.

A few nights ago, my radiators went cold

Having tried all the resets and radiator bleeding etc., I noticed that whilst the boiler was kicking in and the hot water tank was filling, the background pump noise was missing, so I located the pump.

I didn't notice the power lead, at first and simply increased the setting from 2 to 3, without any luck (I also gave the pump a couple of measured wallops in case there was some debris inside, stopping the pump). No joy.

I then noticed the power cable is all split and the live wire's core is actually exposed.

Is it likely (or possible) that simply rewiring the pump may effect a repair? Should I use specialist cable or can I use heavy-duty, 3 core, white-sleeved cable that I already possess?

Are there any pitfalls I may encounter (incidentally, the current plug is of the very old-fashioned small (half-size?) round pin variety which I suspect may be not even earthed.......should I also replace that?).

What may have caused this as I believe the pump is only around four years old?

The back of my upright freezer hides the in-kitchen-wall plumbing and is probably around 3 to 4 inches away from the pump and the cable. Should I place a barrier between, do you think?

I know it may appear that I'm trying to answer my own questions, but am not attempting to state-the-bleedin'-obvious, rather I am nervous of cocking it all up, through my ignorance.

Many thanks for reading.

Please feel free to ask questions.

Is this apparently due to overheating or physical damage?

Can't tell. The cable may have been damaged by the problem.
Your cable will be fine.

The size suggests a 5A plug which would be fine on the CH circuit, but - it should definitely be earthed.
Is it on the same circuit as the other controls and wiring from the CH system which would be ok but not if separate?

Could be overheating or physical damage.

Only to prevent the above.
