Been working to replace the tank used to supply oil to the central heating boiler. The original steel tank (bought used) was fitted nearly 20 years ago when we had the heating installed, and was beginning to leak because of water in the fuel. It was nearly buried under car parts, a log-store shed, seasoning logs donated by a neighbour and various plants, requiring a whole afternoon to relocate stuff.
Today I disconnected it from the underground pipe to the house, then moved it off the supporting piers using rollers because it was too heavy to carry. The piers had to go next. They were constructed of hollow concrete blocks sat on a poured concrete base and with the hollows filled with more concrete. These things should just knock apart, but the first resisted many blows with a large sledge hammer, requiring tiring work with a club hammer and chisel to finally break up. It got to the point that I couldn't hold the hammer properly - my forearms feel wrecked - and I was considering hiring someone to help the next day remove the second one. However, with encouragement from my son we tackled it and it just took a few blows to completely disintegrate.
Tomorrow I'll lay a flat base of slabs and then connect up the new (plastic, bunded) tank, ready for filling.
There's something good about manual labour. It seems so despised these days, but it's very worthwhile.
