Installing 2 & 3 Port valves

[T&Earth]

Hi Everyone

Been asked to change a sticking 3 port valve on a domestic heating system, but dont do much heating work. A pal told me to cut cable of old valve and terminate it in connector bolcks and connect the valve to this thus not disturbing the 10 way junction box. I will look at putting it in to the main wiring J/B just deppends what sort of mess its in, also what tests would you carry out?


Any help advice would be much appreciated

Many Thanks

It's only 5 cores, can't you just cut the old ones about an inch each from the choc blocks in the wiring centre then swap them over one at a time if your unsure where they should go?

I would definitely be functional testing, using your stats, programmer and checking the arm on the valve to ensure it opens and closes when it should and also the boilers firing
