hi guys, does anyone make a tray that a cylinder can sit on with an overflow pipe on it in case it leaks? , never seen it done before, sounds abit nuts but this is for a fortic cylinder {storage tank directly on top} thats in a loft, there whole ceiling is being re done as the previous one leaked ,so this has to be 100% fool proof and future proof, im actually going to use a plastic lid from a storage box with some ply inside for the cylinder to sit on so the heat doesnt soften the lid and then cut in an over flow fitting on the up stand, other then the plastic softening from the heat cant see any problems with doing this? cheers...
