Flexible or stainless water tank

[Graham_Wright]

I had to cut out my two stainless tanks because they were leaking at the welds. I have Plastimo Flexible tanks and no issues after 16 years with them. If I were doing it again I would still go plastic, but rigid polypropylene are probably better.

The benefit of flexible tanks is that you don't need a breather. As you draw water from them they gradually collapse. I was sceptical about the idea at first but Plastimo approved and they work fine.

(An ancillary idea, if I ever get round to it, is that a tank contents sender of the traditional swinging arm type can have the float rest on top of the tank. As it collapses, the level gauge indicates the height.). (I am a gadget freak!).
