My latest rain water system has now been up and running for 5 years and I thought that some of the more unusual features maybe worth mentioning.
Unlike many, I filter the rain water before it enters the in ground storage tank and I do this by forcing the water through a sand bed, the force being created by the working height of the system which is at minimum 3 metres. Pipe work from the various roof gutters through to the tank is of plastic welded construction.
Secondly, unlike most, I take the water from the bottom of the storage tank, from there it goes through a standard pressurisation unit, through a polishing filter and then on to the outlets
My water gauge is simply a "U" tube connected to the tank via a 1/8 hose I blow into this and it gives me a reading in days available rather than litres, easier to understand
Oh and a final point, I don't allow mains water into the storage tank under low water conditions, rather, I simply change over to mains water straight to the outlets in this event
It works for me
