My present toilet system upstairs and downstairs operate not from the water mains supply but from a tank in the loft and when I installed them a good few years ago I had to fiddle with the water inlet to allow the water to fill the bowl.
I’m looking at a replacement Flush King top flush, bottom fill which says that Fill valve minimum operating pressure 0.2 bar, maximum operating pressure 5.5bar. Would this operate on my water inlet system from a tank in the loft OK?
