This way you are getting full usage out of each cartridge of DI resin and you have more purified water. There is a lot of good info on this system on the web.

Also Okanagan water is pretty hard and really puts a drain on your filter cartridges. At least it was when I lived there 30 years ago.

I think I need to change the DI resin. It has almost no black left in it. Probably left it a little too long. Good idea on the dual di filters. I will have to look into that. One thing it seems I need is a pressure booster pump. The psi out of the cold water line is 40psi. I am told I want at least 50psi.


Yes Okanagan water is really hard. I was hoping to get more than 3 months use out of the DI filter. Especially with only making about 10 gal a week.
