I'm currently replacing my heater pump and Heater Control Valve, but i'm not too sure about whether the hoses connected to the right hand side of it, nearest the left wing, have been attached to the correct tubes on the HCV.

From the pictures you can hopefully see that the hose that comes down from the rear of the cabin bulkhead has been connected to the top tube (but maybe it looks a bit more kinked than it should, especially at the bottom).

The other hose from the heater pump I connected to the lower tube.

Has anyone got any idea if this is right or not?

I took some pictures when taking the HCV and heater pump out, but some didn't come out well and were deleted, and the remainder don't show the correct placement of those hoses.

Please help

Sure is one hell of a heating system.

I couldn't find anything in the JTIS or JPEC on those parts, odd considering they are major heating system components.
Searching for heater pump and heater control valve weren't the magic words.

"Assembly valve" brought up that diagram in your link, in my JTIS straight away.

Many thanks.
