does not work as i will be using twin di

sorry if its a nosey question but can I ask why you are going to be forced to go di only ?
I dont have the answer to your predicted resin use but with a tds of 200 I'd consider di only to be the very last option after all others.

i use 2 vessels a 25ltr and a 16 ltr i swop there usage every week 25ltr on a polish then 16 next week and so on i add 3ltres to each a week to top them up as so to speak.

what is your tds mate

[Blue Frog Systems]

wimpoclean uses 4 bags a year - double di on demand - his tds is 90, so you should use about 8 bags i reckon.

Make sure you only di what you need - saves water & saves resin.

im DI only in a first floor flat.it would be impractical and virtually impossible to use an RO.luckily my tds from the tap is usually 35-45 most of the time.i use two 25kg bags a year.

at 200 tds youll probably use 8 or 9 bags a year thats around £500-£600 or £10-£12 a week.not too bad if it keeps you working.another house a week cleaned should cover it.



best wishes

thats my thinking to daz i am sure if i use two di use the first as a sort of pre filter and the second to polish it of it will be ok

tds of 300 from tap

I asked the same question to my mate last week when he was helping me  out he said he gets between 2000-2500lts  for 2 /25 lt vessels and we have got 280 round hear anyway that last him a month tops only .So it only cost him about £20.00 a week no big outlay and not much space needed .I can see his point if that is all the water that he uses

I use twin DI - works out at about 2 bgs a month if I worked five days a week- tds 340.
