Yes & that is exactly what you should do!

I would recommend a 11Ltr vessel & have it after the pump i.e.- sequence- tank>pump>DI vessel>hose reel>pole.

Fill your tank from the tap & pump through the vessel, don't fill through the vessel.

Hi
   I have a 21 tds reading out of my tap and i go directly into the DI Vessel and then into the tank as i was advised that having the DI vessel after the tank makes your pump work a lot harder because it is sucking water through the DI instead of straight from the tank.

You were advised wrongly Sean. A DI vessel has a "free" flow of water through it offering virtually no resistance to the flow. The resin is suspended in the water inside & so not compact.

The slower the flow of water through the vessel, the longer the resin will last reading 000tds. Resin volume Vs flow rate are key here. There is absolutely no benefit of filling your tank through the vessel, there are however many benefits to not doing so.

Do you fill through your DI at full mains speed/pressure?

Winpro's correct i had this discussion with him a few months back when i was setting up.
I'm an engineer and it didn't seem logical to have the DI's after the pump but they offer virtually no resistance.
I set up this way and i have twin 11L DI's to cut back on resin use.
There's a bloke on ebay who sells em for about £30 each.

Nice one WinPro clean  currently using a 11 litre DI vessel to fill my static tank as dont have the room in back of my Pick-up Truck .

But really was not sure about the small Compact DI vessel Gardiners  sell because they are only 4 litre .

But if i was to fit one next to my tank my resin would surely last far longer as the flow rate is virtually a trickle really as i run my pump at around 26 at the minute .

And i run the pump at 22 in warmer weather so could save money longterm with resin also if i run my tank dry i can fill up at custys house without the need to finish work and go home .

You Beauty  . Mike

Hi Winpro
       Yes fill straight from the mains,the cleaning Warehouse advised me to do it this way(maybe they are wanting me to use more resin??)

I wouldn't have thought so. I don't think it would make that much difference to their business.
There are benefits to yourself that could outweigh any extra resin cost anyway.
It sounds like a good idea.

Do you fill through your DI at full mains speed/pressure?

Are you suggesting that DI before the pump is more efficient than double DI before the tank?

Not sure what you mean

What I'm saying is that to have the DI's (whether one or two- as the input TDS will determine the economics for this)
on the van & pump water through them via your wfp pump will be more efficient (and by some way too) than running  water through it/them at mains speed- unless you do it as a trickle feed.

The higher the input TDS the more economical a second vessel becomes but for the sake of this topic base what is being discussed on one vessel so as not to muddy the water!

Hi Winpro
       Yes fill straight from the mains,the cleaning Warehouse advised me to do it this way(maybe they are wanting me to use more resin??)

Doesn't surprise me one bit that you were advised wrongly unfortunately.

Fill your tank with tap water & then pump through your vessel AKA purifying "on-demand". You'll get maximum efficiency from the resin this way. You'll also fill your tank faster, waste no pure water, be able to fill up anywhere etc etc.

Always have the DI after the pump (as in Winpro's sequence) as you can suck resin from the DI tank and block the pump. Sticking a filter inline can help as well, main thing is to keep the resin getting into the pump at all costs

[SunShineCleaning]

Yes I should have said DI after the pump.

Just to clarify, I have 55-65 TDS water and have DI'd for 5 years after my RO broke.

I use twin DI and rotate them when the first one get to 55TDS

My sequence is Tap; double DI; tank; pump; water heater; reel; pole.

I'm interested if it would work out more efficient in the long run if I did it as you suggest.

Tap; tank; pump; DI; water heater; reel; pole.

Any comments?

If you are filling the tank through your vessels from the tap with a flow rate greater than your wfp pump then yes, having the vessels after the pump would increase your resin economy.

[SunShineCleaning]

Would I use just one DI or two? Does this affect the pressure at the brush-head?
