using combined feed and ex setup.

using the above with single 22mm pipe, is it acceptable to take the vent/feed pipe directly into the bottom of the water tank in loft, or do i need to tee into bottom then still overhand with 22mm vent? thanks in advance

Any particular reason you want to change the existing situation?

i need to change the tank as the old one is galv, and would be much easier to just go into bottom with one pipe.

Its all down to the mans install guide, and if they approve of that type of set up, baxi/pott not a problem.

Can't you just change the tank and leave the expansion pipe as it is?
