R/O unit auto shut off

[Madreefer]

My only other question would be how do you put a second 'emergency' line in? I would like to do something similar, but do you have it plumbed on a totally separate hose, or does your main feeder line to the reservoir split?[/quote]

I just have a hole drilled in my resevoir a few inches above the float valve with a hose that will drain in to my floor drain in case the float valve fails. It is not necessary and not attached to the feed line. Just a precaution I took.

been using a furnace humidifer float valve from HD for about 5 years off my aquasafe rodi unit with zero problems. Also as Madreefer, just have a bulkhead then tubing running to the floor drain as an emergency, bulkhead is above the high level mark in the reservoir.

Over the years have had to clean and replaced the auto shutoff valve and one-way check valve (rodi unit will stop outputting clean water but still produces waste) so have the waste line that when I go into the fish room can hear it trickling into the floor drain. Idea is I'll notice if it seems to be running continuous.
