is the f/e tank full if so the cold feed to system is blocked.

Hi, Thanks for reply i think your spot on F/E tank is full.Just a shame the tank is in the worst possible position cant even fully take the lid off its about 2 inches from the roof and wedged into the corner.

lovely.
if you have a magnet place it near tee where it joins the system if it sticks its where the block will probably be.

Hi, Thats a really smart idea will try, any idea how blockage can be shifted.cheers

you can cut the pipe and renew that section.

or cut pipe and clear blockage and refit pipe.

Out of curiosity could you explain why the magnet would stick near the Tee on the F/E tank if it was blocked

Have a look at FAQ 24.
Also do a Search for blockages
