.... and looking for some advise. I have a Primatic system and I need to drain / shut-off the domestic side (hot) to carry out some work (fitting a new kitchen). Problem is I have no obvious stop valve on the feed from the tank. I tad worried because a few years back worked on the same system (central heating side) some how caused a vacuum lock and collapsed the tank 🙁 any advise would be most appreciated. Ta.
