I just run my waste water down the laundry line. They recycle that down at the sewage plant I guess......
I've tried using it for a few things, but in winter I can't do much with it. I know my output is really a lot lower because of the colder water in winter (makes darn pure water tho...). I only get 42 psi out of the tap.
I teed into the hot and cold last year, it made a big difference for me on the output. But it was too hard to control the temp, and I feel it subsequently lead to an early departure for my membrane...........
When I'm just looking at hours vs output, I'm okay with what I am seeing. I'll measure the waste water tonite and see what kind of volume I get. Then I probably won't be so okay........
