Are the pipe centres set (do they come out of tiles)? As this could narrow the number of replacements available
yes 150mm centres and and come out of tiles
Yes set at 150mm and come out of tiles.
ok, let me look into it, most of them are 152mm centres, could this be the case?
I would say 150mm but if 152mm is standard would not argue the point
Youn can use any of the Bristan exposed valves to replace this;
and many more - check out their site (but buy locally cheaper)
