Lately it seems they may be treating the water supply of SE Michigan. PO4 in water post RO/DI is @ 10 after all new cartridges! I have had a couple people w/ same issue and was wondering if anyone else is experiencing this.
I have a new membrane, dual DI chambers, 5&1 micron sediment filters, and 1 micron carbon filters coming from BRS.
New RO/DI configuration will be as follows:
1- 5micron sediment
2- 1micron sediment
3- 1micron carbon
4- 75gpd membrane
5&6- DI

Really hope this takes care of the issue
