HI

I soon will have several IBCs at ground level to collect rain water.

(I have new pipework in place for the toilets and outside taps which all
go back to the loft, its currently connected in the loft to a mains
water pipe)

I have a cold water cistern in the loft which I can connect up to the
house toilets and the outside taps.

Now where can I find a good value for money submersible pump that I can
put inside the IBCs and pump the rain water to my loft tank, and will
sense when the loft tank is full? I presume I can use a ball cock
arrangement?

S.

And no you can't use a ballcock, that would leave the pump running.
As submersible pumps are water cooled, it would overheat and burn out.

Won't you need 3 pumps or arrange the IBCs to have balancing plumbing at
low level? In which case you could have an external pump.


I am using 10 IBCs, 5 vertical stacks of two if that makes sense.

The upper level of tanks will be connected to its tank below. So the
idea being with 10 off 600 littre IBC's I can store up to 6000 litres of
water.

The bottom 5 tanks will be connected via a "bus bar" pipe so to speak
and tank breathers fitted to all 10 IBCs.

SO I can either use a submersible pump in one of the bottom tanks or use
an external pump connected to the "bus bar" pipe.
