Mike, Maxie has problems.

"Never" have a tee at the end of a pipe, in either gas or water. This acts as a brake on flow and pressure. The mains pipe should have been direct to the combi, and the other leg teed off. Many installers do not install

3-port valves because of this and use two 2-ports.

Also pipes must not touch each other when crossing.

I'm not sure what there is to show, since I don't so much DIY as just get on with it. We repainted the front of the house, are you really interested in watching paint dry ?

When there are jobs around the house which need doing, I don't take photos, I just do them

... and I have a sarcastic streak, what's new?

Maxie, are you tackling your weight problem?

Don't we all... ex wife won't pay her debts, motorbike I can't sell, empty bank account, it's raining, beginnings of a toothache, nappy needs changing, it's raining... etc. :) But I still smile!

See, we're all learning stuff from this thread.

Fair enough. The 1 metre distance is from the manufacturers of plastic fittings and I suspect they probably err on the side of caution to cover themselves.
