Replacement for Myson MPE322 valve

[mike6182]

Hi Everyone,

My system has a Myson MPE322 mid-position valve that has given up the ghost & needs replacing. I was thinking of replacing it with a Honeywell V4073, because I'd heard they're better, but I'd only want to do that if it was a straightforward swap and didn't involve any pipework or significant wiring changes. Can anyone offer any advice please?

Cheers,
Mike

The 4073 is better and an industry standard.

You will probably need to remove the old olive and nut from the pipes and there might be very slightly different lengths needed usually accommodated by movement in the pipes.
