RO membranes

[Doug]

Recently purchased a 50gpd membrane to replace my 100gpd, as I read and/or someone told me they were much more efficient.

It makes half or less ro water then the 100 did, thats for sure but almost the same amount of waste water. How the hell is that efficient. What a poc. Plus cant get a 0 tds reading on the new membrane. Still reads 6ppm, a couple weeks later.

AArrggggg.
