It didn't really give many specifics. We only had issues once and that was January  last year when we bought a new set of the black filters. They weren't filtering and were leaking the filtration media into the water. We contacted them and they replaced them no issues. I need to look into lab checks of the data for cost because I probably should have verified that on my own already. Now I have to go down another rabbit hole. Thanks Beave 

 Yeah. It's so hard to do all the due diligence one needs to do these days since EVERYTHING is compromised in regards to food, soil, air, and water. 

Taking responsibility for t failures of others is a long, hard row to hoe, but, I think it might be worth it.
