We did find someone selling a hardened glass table top from a 70’s cruise ship, and it fitted perfectly. It had a hole in the centre too, which is perfect size for a 22mm copper pipe.So I’ve been looking at those garden hand pumps, and using the water is on the cards.@nox_uk your next project should be designing a siphon using a foot pump or similar to use the water for car washing, garden watering etc.
