Part for worcester 240 combi boiler??

[peted]

can anyone help? I need a part for my worcester 240 combi boiler but don't know what its called or what it does. Its a H shaped fitting that joins the central heating flow and return pipes (22mm pipes coming out of the bottom left hand corner of the boiler) it has 2 or 3 other pipes connected to it to. I think one is the pump and another goes to the pressure relief valve. It has a screw in the middle and a circlip stopping the screw from being unscrewed. The screw is dripping and when i tried to get it out it wouldnt come and now its a right mess, so i want to replace the whole thing, but the people in plumb center want the part no. or atleast the name of the part. Ive tried worcester technical but can't ever get through.
Thanks Pete

I think it may be the heating bypass assembly, but I could well be wrong!

There should be an exploded diagram on the HRPC site.

Why do you want the complete part for ? its a pig to change and the only bit that goes faulty is the "o" ring if someone fiddles with the by pass screw. Just order a new screw it comes with a o ring , drain down , remove circlip , unscrew as much as poss then pull out screw useing circlip pliers in the screw slot. takes 5 mins.
