tds meter, ive got one u can have 10 plus postage jonisonvespa@yahoo.co.uk
pump controler, adjusts the water flow speed
400ltr tank 124 on gardinerpolesystems.co.uk
di tank and resin

[dave0123]

Resin and the blue canister to polish off the water

[ccmids]

tds comes with kit  yes was not sure about resin tank my tds reading is 228
does that make diffrance

[ccmids]

what size blue canister would i need

[dave0123]

You will still need resin but your RO should bring your TDS down quite low aslong as the pressure is good.

You probs be fine with a 11lit vessel but could get bigger if you wanted just means you dont need to change it as often.

[ccmids]

will it bring tds to 000 or will i need 2 blue canisters

[Ian_Giles]

My own 4040 brings the TDS down to around 0.006ppm, at the moment I'm not bothering with resin,bit of an experiment I suppose, but I'm really not sure it the water needs to read 0.000ppm to be able to clean spot free windows.
So far that has proved correct as I've not been able to tell any difference between windows cleaned now and windows cleaned when I had my 100 gall per day system which always had the resin vessel to give the water that final polish.

If you have good water pressure then your membranes will work very effectively. a tap water reading off 0.228ppm is slightly on the hard side and the membranes may not quite bring the TDS down low enough to not bother with resin vessels, but you won't know that until you get your system all fired up and turned on.

For flow control on your pole hose a simple inline tap is all you really need.

My own is situated between the van tank and the pump (as against after the pump) so there is no risk of the pump cycling if the tap is closed to far.
I've been using this method for over 2 years now with any problems whatsoever.

hi ian when you say inline tap is that the one that supplies the water to pole like the one you can have by your belt

[dave0123]

will it bring tds to 000 or will i need 2 blue canisters

Yes it will bring it down to 000 you wont need two of them!

On my system i use 2 because the water pressure is crap! so my membrane doesnt work as good as it should do really and the pump helps a little but there is not enough flow either so my tds only comes down to about 18 from 400 odd then i use 2 vessels  saves a bit of money.

Do you know your pressure of your water btw?

[ccmids]

presure is very high .
 do you know how often will i have to change ro membrane

[Ian_Giles]

hi ian when you say inline tap is that the one that supplies the water to pole like the one you can have by your belt

Yep!

my flow control is in the van, never felt the need for it on my hip as I can always fold the pole hose and pinch off the water flow if needed, or pop the pole hose off the reel hose (easy enough as I have a rope sash over my shoulder attached to the reel hose, so it is very easy to pop off the pole hose.

Once my flowrate is set, I rarely ever need to change it.

Well maintained your membrane should last at least a couple of years.
Change the pre-filters every few months, keep the membrane frost free and flush for a few minutes before each use, oh, and don't adjust the waste/pure ratio to high either!

Ian

[dave0123]

Every 2/3 years i think is the normal for membranes! you will have to change your pre filters they say every 3 months but i change these more regular they dont cost much anyway a few pounds.

[ccmids]

i did not know you could adjust the waste/pure ratio to high is there some sort of swich i need to get

[Ian_Giles]

You have to manually adjust your pure to waste ratio.
Gaps will supply you with what you require to do so.

The 'waste' pipe has the flow control tap on it, you will have instructions with your kit, to begin with your waste valve will be fully open as you run your system for the first time...for about 10 or 15 minutes to allow the membranes to have the preservatives flushed away.
You will then slowly close the valve until you have a 50/50 ratio between the waste and pure.

You then check the tds reading of the pure, basically adjusting the valve (tap) until the tds of the pure being produced begins to climb and you have then reached the optimum balance for your particular situation...

i think i know what you meen ,  would you rate gaps as good company

i think i know what you meen ,  would you rate gaps as good company

I have dealt with June who runs Gapswater for a good while and can only rate her as excellent.

Dan

[dave0123]

I got my system from June at Gaps and the service was fantastic! and she helpe me loads with my low pressure problems and low flow of water to get the TDS down as much as poss!


Very helpful

you need to measure tds after di, u need hand held tds meter
