heating tripping rcd help

[jasonk]

Hi can anyone help before i call the plumber out, I put in a new shower pump yesterday just a replacement for a more power full pump and everything worked fine last night and this morning, i switched the heating on this afternoon and it caused the RCD to trip, i ahve reset the RCD and everytime i turn the heating on it trips, when i put the pump in i turned off various stop valves in the airing cupboard where the pump and tank are located and wonder if this has caused a problem, any help would be great full.

Could be various things but Id check the pump to the heating 1st,,

There are plenty of possible causes, earth system fault which you have disturbed, faulty wiring on your new pump, coincidental fault.

You need a competent person with an earth leakage clamp meter.

Look above your motorised valves i bet there is a drip from one of valves you turned off going straight into it .

If it was not on a rcd i would say put 13amp fuse in turn lights out and look for the flash far quicker than any of that proper testing shi#e. Only takes a couple of mins for eyes to refocus

woild that be a clamp on 13 A fuse

Namsag still laughing at your testing procedure. Quality

Reminds me of when some tw#t used silver foil for a fuse on an old baxi 572 wiring had burnt out and as pulled tray out it shorted onto base neva threw a burner tray away as fast in my life and as ran to turn power off it was bouncing everywhere.
Oh its been blowing fuses for weeks but the foil stopped it they said. Honest never swore at them.. well not for that long

There is a scheme where I used to work on that used to trip the electrics when the heating was turned on....

was always the fan.....glow worm fuelsavers various sizes.....if you were real unlucky it took the PCB out along with it.

As suggested big bag of fuses and disconnect things till it works!!!

Superduper you will have to explain what a scheme is they are all English.
