Bought a new water outlet for the head as the old pipe looked like there was some corrosion on the bottom.

While on the phone Phil said they have had a bit of trouble with genuine top hoses weeping through the reinforcing cord. When I pulled mine off I can push liquid out the ends of the pipe at the cord????

So for now I have put the new water outlet, old (good condition) top hose back on and put No3 on the joins.

Will see how it goes and talk to Phil about a replacement.

Any one tried silicone radiator hoses?
