Hi I would like a little bit of advice please. I am thinking of going over to wfp so my question is this . firstly were is the best place to get the products i need . I already have a RO system but the water flow is so slow I think it would take a week to fill the tank. If I get a 11L resin bottle what is the average cost and how many 4 bed houses would it last. or do I have to use both the RO system and a resin canister .

Regards
Steve

Before you go any further you need to know what TDS reading you have at your tap water.

yep find out your tds at your tap first mate.

if its pretty low then you can do away with the hassle of an RO and just use double DI which is so much easier,faster and more convenient.


the smallest tank if your a sole trader mainly domestic window cleaner would be a 350L if you plan to wfp most of your work.

Thanks Guys My tap water is reading 265 i guess this is high. when I run it through the RO it is coming out at 76 . what would you be happy with from the tds reading. for clean windows.

thanks

That is a very poor output from your RO, it should at least bring it down to 10% of the input tds, if you want to produce water fast then you need a 4040 ro.

With your input tds into a 4040 RO, you will probably find it will bring it down low enough not to need resin

Hi Guys I have just run the test again and it is showing 010 on the tds reader is this ok .

Cleaning with 010 is fine, but if you buy an 11L resin vessel it will last you months before it needs changing.

My ro was coming out at 010, and the resin in my 11L vessel lasted 18 months before I changed it

Lee what do you think of the 4040 RO? How many gal per day does it produce bud?

You probably have the 50GPD RO system.Consider upgrading it to 450GPD.
