Ill be here till 1.30 PM however I will then be in work till 10.00 PM so wont be able to get back to you till then

Cheers

We will need to know the model number of this valve to enable to advise you correctly. This can usually be found on the inside of the silver cover.

The last time I purchased a Wilo, there was a pair of washers enclosed, (which was sometime ago as I am a "Grunfoss addict).

Cheers

Cable diameter. A priority valve as I remember has only LNE and not 5 wires.

Beg to differ, the Honeywell V4043H has 5 wires as used in the "W" plan.[/quote]
The 4043h has indeed got 5 wires but it is a 2 PORT and w plan needs 3 ports

You are correct, I was thinking of the salus mv322 diverter valve but of course this has not got a silver head. Thanks for informing me
