Packing all the stuff back in the van last night after pressure washing, and somehow....... I don't know how but it happened. A 25 metre high pressure hose caught my merlin ro as the lad pulled it.... I just heard something hit the floor, end piece came off but didn't looked damaged but when I connected up water was gushing out the sides

Omg !!!!! 

Anyway was checking water out this morning in some jobs and I found 1 that was giving a tds reading of 051..... Happy days so I filled tank through Di bottles.

At what reading would you think is acceptable to go direct to Di and not bother with ro.

I have a spare merlin that I will sort out but will pick done brains first.

My tap water is 90ppm & I've been twin DI only for 12 years.

[ChumBucket]

Incidentally, I cleaned with 66ppm last week with absolute spotless results!! Even surprised me.

When using an RO I wouldn't want water to be more than 20.

How long does your resin last or how often do you go through 25L bag

Using twin 11ltr Vessels in sequence & purifying on-demand (vessels on van & pumped through), running a 500ltr van mount I use a maximum of five bags of resin per year. That's a max of £375 & no waste water.

That's sound that tbh.

I also do similar in a sense I have an 11L DI bottle after pump, this is because I use the same tank to pressure wash and sometimes just fill with tap water.
So I put the hose back into the tank with tail end piece into it so as am filling up with RO then DI into tank it is also recycled around another DI to get any contaminates back though and clean tank as well, 

I think I have only ever bought 3 or 4 bags of resin in 2 odd years,

NO WAY. That's close to what my tap water is. Never tried it to see

Yep, that's rubbish Ionics resin for you, went from 002 to 066 in two days!!

[Small but perfectley formed]

Ionics resin it's  excreta sent mine back

[paulben]

If you add an additive to tank TDS will be higher . My TDS starts off at 001 and ends up at 16 Additive I put in is 176 Result spotless windows think too much is made of TDS having t be 000

thanks for that mate.i nearly ordered some from ionics the other month!i think ill stick to getting mine from gardiners as delivery is super quick!

My water is 150ppm and I have to vans, 1 single and 1 double user all with twin D.I on demand.

11lt vessel changed every 2 weeks and still cheaper then having all that waster water / holding tank

[Matt.]

So in hindsight guys if you could get water out of a tap at 51 would you just go double Di and not bother with ro

[Roberto Smith]

TDS around my area is 250 ish and I use twin DI in the van using customer's water to fill  my tank. Too awkward to use RO from my flat and renting a unit would work out much more expensive. Probably use 2 sacks of resin every 6 to 7 weeks. Way i see it, it pays for itself after 1 day all the rest if profit and it makes my life very easy 

[TomCrowther]

I tried the ionic resin too. Bought two bags of it and a, it doesn't last as long as tulsion and b, when it goes it goes quick. No creeping up. Mine went from 2 in the morning. Left it trickling through twin di into the static tank. Came home at lunch and checked again and it was 17. not good. Tulsion would stick at 2-3 for a few days and then slowly rise.

Yes, ditch the RO.

Anyone thinking of trying Ionic resin- don't bother!

[NWH]

220-240ppm in most parts of Sussex where I've dipped my meter from time to time

[Matt.]

Found a better one now with tds 047 😃

Be a bit of a sin not to fill me tank up

[ChumBucket]

You want to be filling the tank with tap water & pumping through the vessels Matty. Most economical use of resin to purify on demand as this gives a very slow flow through the vessels.

[Matt.]

Well I noticed that when I slowed the tap down the tds level dropped.

Cheers chumbucket, I got the water going in an I have got the pump goin through a Di in the van circulating the water what was in the tank, I was pressure washing last night so giving it a good clean out also.

Thanks for your help
