Oh I see, my reading is 72 ppmBefore buying anything you need to know the tds of your tap water.
This is a di system, hence why it appears to be cheap. If you live in a hard water area you need to consider an r/o.
Its the most common type. Uses the champs housing. Housing and membrane purchased from GAPs Water.spruce what sort of ro 4040 r u using
You don't need an RO @ 72PPM tap water, I wouldn't bother with one either. You would be better off with Two 11 Ltr DI vessels rather than One 25 Ltr vessel though as this would give you better resin economy.
I've been DI only for 12 years & never come even close to spending £1000 on resin per year. Running a 500 ltr van mount & with a tap TDS of 90 PPM the maximum I use in a year is 5 bags.You are right, you don't need an r/o with 72ppm tap water supply, but in Paddy's case, do the running costs add up?
Resin could cost £1000 by the end of the first year using our example. Even with the r/o's initial purchase price he will have reached break-even before the first year is out.
If Paddy was on a meter then this would be a different story as the cost of water has to be considered. Again using our example and our r/o setup, he would use 192000 liters of water a year with a 50/50 pure to waste ratio. On a meter that's a fair bit of water to pay for. But he isn't on a water meter.
If he was filling up from customer's taps then di on the van is the way to go, but not all people with outside taps leave the supply on to them, especially over winter.
Customers taps are also sometimes not in the most convenient place either, so a long hose would be needed.
The perception from onlookers could be that the window cleaner is stealing, even if he has his customer's permission to help himself to water..
It would depend on how much water you use & if you view all the above as beneficial to you?I'm currently using a RO with my water at 105 would it be better to use just di?
Hi Andy I'm in Newcastle upon Tyne area, were with Northumbrian water btwpaddy where are you. i come under southern water and every one under southern water will be on a meter by the end of 2015
