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?

SOT...

As everyone expects that just about all taps are connected to a
potable mains water supply, I would suggest a clear notice on the
external tap: "Rainwater - not for drinking".


Ditto the pipework....

ALl my potable cold water and hot water pipes are all in copper.

I did the rain water pipework in white plastic so its clear whats
inside the pipes when floorboards are lifted

White plastic pipe is intended for domestic waste water, so most people
would assume it to be empty unless something was actively running to
waste. Grey BS 3050 pipe would be a better choice as being something not
normally found in domestic installations. Also, if the water is being
pumped. BS 3505 pipe is pressure rated, while white waste pipe is not.

Alternatively, you could apply British Standard identifying colours
along the length of the pipes, to show what is in them. For drinking
water, the colours are three equal width bands of green, blue and green
respectively. For rainwater, the two outer green bands remain, but the
blue one is replaced by three equal width bands of grey, black and grey.


The white plastic pipe I am using is NOT waste pipe but either JG Guest
PEX or FloPlast PEX in eiether 15mm or 22mm bore.

I'm not going to cut my joists that deep to accommodate 40mm waste pipe
and accommodate the required fall too! I'd weaken the joist too far.
