with that tds at the tap you could just use two di vessles. the resin would last a resonable amount of time and wont have the problem of long fill times. if you choose the di route i`d fill the tank straight from the tap and pump the water through the di`s when your using the system. It will always be cheaper on resin to use an ro but its not always convenient to wait untill its full. in time invest in a bigger ro.
Di before your tank mate. Tap, di, tank, brush/hose. This will stop the pump pushing hard to get water through the vessels and will let the battery last longer. Let your water pressure do the hard work for you.
thanks lads, never thought of doing it the other way with the di after, is there any way i can keep the auto switch off do you know?
Not true, mine pumps through 2 x 11ltr DI's & I run my pump on it's lowest setting- 1 0n a digi varistream
QuoteNot true, mine pumps through 2 x 11ltr DI's & I run my pump on it's lowest setting- 1 0n a digi varistreamIn the name of all thats holy. If you are di only there is no need to have the vessel after the pump, regardless of what setting it is man. The pump will simply work harder to push the water flow through (in your case 22 litres) of compacted resin. Use the nut and fill it slowly or quickly, whichever suits directly from the tap, powered by the water mains.I used to have it like you until someone clever explained in simple terms that I was doing it Arse 4 Elbow.
I never did under stand why people use di after pump and or tankIf you have pure water in tank there is no need to carry the extra weight.

Because resin lasts longer with a slower flow through it. (& I've proved it)

(& I've proved it)You can fill your tank super-fast direct from tap.You can fill your tank from any tap.Extra weight? what 2 DI vessels, you're having a laugh? :

QuoteBecause resin lasts longer with a slower flow through it. (& I've proved it)Mac, Im getting fed up so this is my last post on this one.Resin will deionise the same amount of water whatever the flow rate through it is.If you use a slow flow rate, then of course it will last longer because you are using less.A stronger flow rate and of course it will exaust itself more quickly, but......the amounts by volume will be the same at the end of the resins life. Give or take a few fluid litres.
my setup is exactly the same as macmacs ive leave each morning with about 20litres of water in my tank i fell anywhere no watermetres here coming near the end of the day i drain my tank no matter how well i have it secure i feel safer when its empty
