After a trip to our LFS with 10 water jugs (1+hr round trip), realized how unsustainable it would be to have this as my water source.
Got the BRS 4 stage plus 75 gpd RODI and set it up downstream of our whole home water softener. The incoming TDS is 2 and output 0, which makes me wonder if I even needed this thing anyway? Regardless, it’s all set up! The RODI water is plumbed into a 10 gallon bin with a float switch and the waste line is directly plumbed into our sewer system via an air gap fitting. The air gap is a physical disconnect between the water filters and any sewage preventing any damage to the softener / RODI. Took 3 hours to fill the bucket, so not bad!
And of course, I fell victim to having the darn flush valve the wrong way

. At least I finally figured it out after an hour.
