why don't you just drain system and replace the 3 port valve......sounds like you need surrey flange for drawing hot water into shower

Thanks for that Dean. Is a Surrey Flange expensive or difficult to do? It is what the engineer recommended too.

Shows how your supposed to fit a shower pump and the advantage of a surrey flange.
Didn't realise you had a pump on the shower ..... the surrey flange seems to be the solution. A test would be if you could bleed the shower and
then run it with the hot water turned off (ie no bubbles in the hot tank). If it ran well then, it would indicate it needs the surrey flange. If its
still problematic then i'd guess its pump related.
Probably best to try and fix one problem at once otherwise you'll complicate matters (which means my posts aren't helping - sorry).
ps quick google says surrey flange under 40 quid to buy. They're the easier flanges to fit so probably budget a 100 to 150 quid for a plumber to
buy and fit.

Thanks for that Mike. It's not an indepedant pump but I think the shower has a pump built-in - at least it's branded a power shower!
Interesting that most of those diagrams include a Surrey flange - I'm sure we don't have one and it looks like we need one!
So it looks like it's never been right and the three-way failing has just made things worse....
Thanks again
