Cork floor tile, that's a good idea. I need to order in my plumbing bits from BES so I can also do the pump mounts (both of 'em!).
Got a patch of burn on my arm, must've had it exposed and a bit too close to the arc on the welder yesterday.
I'm a little concerned that mine is a bit high, it currently stands at 2.0m to the tip of the cap on the access hatch, but I have 2.1m to play with in the outbuilding so think it'll be OK.
