I have a 400 litre flat tank taking up room in my garage. I have used the elbow fitting on my new tank, so it will need a new one of these and it has a hole on the side near the top which is where I filled it from although this can either be used to fill up or simply shut of with a hozelock stop connector. It needs a bit of a clean ( outside) it's been in the garage for a year but if anyone could do with it, it's yours. I am in Cheltenham, Gloucestershire. First to contact can have it
