I have two that are linked side by side.
I need very shortly to put one on top of the other.
I cannot work out logically how to do it so that both tanks
can be used.
i.e the gravity bit.
Have 1 transfer pump and obviously one feed into a tank.
Does that make any sense to anyone ? any ideas.

this is like the krypton factor for all those with a static ....... hmmm .... i have two together linked with professional ibc fittings but one on top of the other ...pass , too late for me

[russ_clark]

is that one of your pure promises ??

I have two 1000L ibc's on top of one another (but not touching each other) and a 700 ibc off to one side at a half height about 2ft off the ground so that its neck is higher than the bottom 1000L tank but lower than the neck of the top tank.

My r.o feed (after the resin) goes into the top tank which due to the layout of my garden can gravity feed via a 2" pipe to my van or trailer or the 700L below.

When the top tank fills to the overflow it  overflows into the 700L. This tank can also collect rainwater via a switchable diverter from the house roof.

The 700 is joined to the bottom 1000L via a 1" pipe - in the middle of which is a T piece with a tap to the transfer pump.

This means that the bottom two tanks can each be switched to each other or each to the pump or both to the pump together. Or both can be shut off.

So - the top tank is gravity only and can by gravity fill the 700L which can fill the 1000 at the bottom by gravity or pump.

headache after reading that

that really is the krypton factor !!

haha pure promise indeed

Ibc tanks are designed to stack, pump in bottom tank, s60 coupling with hose from it going into lid of bottom tank. When bottom tank empty then dump top tank into bottom tank.

any picture gold

Thats ok if you are emptying tanks of water - but I am talking about filling them up
whilst they are staked??

[alanwilson]

Pipe from ro into top tank, leave valve open then when bottom tank full close valve to allow top tank to fill

Or have I missed the point?

s60 coupling,were are they available?
cheers bob

Whole point of the excercise is to fill up both tanks whilst away from base.
Alan your method would work but you would have to be there when bottom tank full to close valve.

Only way I can see is to have a float switch in the lower tank which opens circuit when the tank is full and operates a solenoid valve in the pipe connecting the two IBC's.  Ideally the float switch should be 12 volt and operate via a relay to open/close the 240volt solenoid.  All wired 'fail safe' so you don't get a flood if the power fails.

[alanwilson]

That's prob the best way to do that.

Bob, s60 couplings available here

What's the most cost effective ro to have on a static system please
