Water tank
So far the most painful job it was terribly crampy, also like taking your very last pullup before you collapse. The weight of the drill trying to squeeze it in impossible places took me a couple of broken drill bits and several more hours with tears, pain and frustration.
Water Filler
Little did I know but it wouldn't open. Couldn't work out why. It wasn't till I took it of and had a good look, the hole was stopping the opening mechanism, a bit more to be cut rust proofing fit and now it's working ok.
Shower drain.
Water gauge.
A must have so you don't run out of water or at least you see it before you do.
