Man this discussion looks like SHUT-THE-DOOR you mentioned tap water!
NA-NA-NA-NA-NA…I can’t hear such malarkey! LOL
Dats not what I’m saying man! Geez. Apparently for a word guy I am having my challenges reiterating the notion that I have run across. So in this video at about the 5:30 mark he speaks of “the drive thru car wash system”.
So it is NOT WASHING WITH TAP WATER, it is an alternative to using up the cost of resin to rinse a heavily soiled window in order to get it completely clean. Of course on a maintenance job it would be a mute point.
I might also add that I do see the benefit of an RO/DI system such as the Xero Pure, but at a cost savings starting out with a DI only this is a makse-sense kind of way to not blast through resin in a high TDS area.
Hopefully the video makes more sense than me because it appears I’m being taken as saying…“just wash it with regular water. What? What?” lol
