Question for those with twin IBC set ups, do you fill from bottom?

Just thinking the weight/pressure of the water in tank would stop the flow??

It's early and I'm full of cold so please forgive me

It would depend on the flow/pressure from your ro. I have a pumped ro and the water comes out at good pressure and would probably force its way in. if the ibc was full to the top the pressure created at the base would be 0.1 bar or 1.5 psi so not huge but still enough to restrict your flow of water in if it's only a dribble. The tanks can be joined at the bottom to self level but probably best to pop the hose in the top somewhere.

Flow rate isn't great, so will top fill but use bottom taps to self level.

How efficient will 1/2" hose be for self levelling? Only want to use 1 pump for both tanks.

Cheers pal.

Not efficient at all

Sorry, why would you want to fill from bottom?

[Perfect Windows]

Fill it from the top.  It'll soon end up at the bottom.

i have two ibcs connected at the bottom but i fill one from top with no booster pump
and they do find an = level but you need to have a 5 mm hole at the top to let the air out

The 1/2" hose will be fine for filling from the ro as the flow wouldn't exceed the max that the hose could transfer. But if you are thinking of dropping a submersible in the tank then it probably wouldn't keep up to allow the water back into the one with the pump. How much do you carry on the van? Assuming you don't use more than 1000 at a time you could put a transfer hose between the top level of the tanks. This way no.1 tank would fill to the top then start to fill the 2nd tank. You could put a tap in the bottom transfer hose to allow water back in to balance if necessary. That way you can move your ro hose into whichever tank you want and the other becomes your reserve. your pump would be dropped into whichever is fullest but the ability to produce 2000 litres without risk of overflow is maintained. Hope that all makes sense.

Not a lot by the sounds of it. Talk about over complicate things

simon you want proper ibc hose and connectors about £70, worth paying in the long run, I had 4 linked in my unit, standard hose will take ages to self level.

Sorry Steve.
I'll try to keep any explanations simpler in the future
