Hi...I fancy adding one of these to my existing 4040 system. But most seem to come with 1/4" fittings. I don't think I have any 1/4" pipes in my system. The cleaning warehouse does one with 1/2" fittings, which seems closer, but I think my fittings are all 3/4".
Has anyone fitted one and can offer me advice re what to buy? Please!
4040 are 1/2" fittings and piping which I have kept.
Lots of these

I have the twin sensor unit. First sensor between the r/o pure output and the di vessel. The second after di and before the storage tank. If I want to know what the tap water tds is I use my tds meter. I know my first reading after r/o should be 3 and after di zero.
If the reading after di is 4 then I will do a tap water tds check. I know my membrane is running at 97% and 3 is 99% of the time. Our tap water is between 120 and 150ppm. There was a time when it was in the 80's and the reading was 2 but it hasn't been that for years now.
Your di vessel could be 3/4" so would need reducers but most are 1/2". My di was 3/4". It came with 3/4" male to male threaded connectors. I had a couple of washing machine filler hoses. I cut the hoses off and pushed my hose onto the barb end. They have worked this way for 8 years now.
