  Hi Guys, I am new to the forum and was just wondering if you could help me with a question I have got.

I currently use a wfp system with RO. Someone has told me that they collect rainwater in storage tanks then transfer to their tank on the van, and clean windows that way. is this system ok ? as I am in a soft water area. The tds reading I get from rain water is 039. can anyone help

Yes,

There are a lot of people that say you can use rainwater although I think before you transfer it to your tank, you would be better to put it through an RO setup first to be on the safe side.

Also collecting rainwater saves you a lot on tapwater.

hope this helps.

Kind regards.

I'm very surprised at the tds reading. My own collected rainwater comes in at anywhere between 002 and 008.

You might want to look at the surface that you're collecting from as the dissolved solids are probably coming from there.

mine is 30-40 i have like sand cement tiles so the tds rises from them.

looking into using pond filter media of vrious grades to remove the sand and then a sediment and charcoal filter to reduce the tds more. should get it to about 15-20 (i hope) before it goes through DI

On a water meter so the saving should be substantial.
