Must be an Aquasafe day, I just set mine up this afternoon
Ran into a couple of glitches...
The system had to go into my basement rather than the recommended under sink installation. The red feed water hose came supplied as 2 ft and I needed 25" to reach the nearest cold water line (it came with a factory crimped fitting, so I couldn't just replace the length of hose). Fixed it by extending the hanging bracket with a 2x4. Now I just have to remember to duck when I go under this particular area...
The yellow waste water line was even shorter, but I modified it by sticking it into a length of aquarium siphoning hose and then running it into the drain.
The only 2 fittings that I actually had to attach, leaked like sieves. Ran to the local co-op but they had just sold the last container of plumber's compound (Ed's 1st choice) and only had teflon tape left (Ed's last choice)
8 tries later and the teflon taped fittings only "slightly" leak now

I've given up and sat them in a basin...
My house water pressure is pretty poor: ~40 and the tds is ~290. That combined with a very cold water water feed, is presently giving a pretty slow RO/DI output, compared to a strong waste water output. I've not measured it yet, but it's prob close to 8:1
Just happy I finally got this thing set up
