Asked this in New Hobbyist but havent gotten any help in several days. Getting tired of carrying water and have vacation planned in few weeks. I want to set up a top off system but need some advice please. I have a RO/DI unit set up already for evaporation water but have to carry water from it to tank. RO unit is on back porch because fresh and waste water close to there. My tank is in living area of home and I have no place to put RO unit near tank. How far can I run the water line from the RO unit? It is about 35 ft from the unit to tank. If that is not too far I can run line under home to tank then set up top off in the sump under the tank. Can I leave water to RO unit on all the time with top off system and when it gets low the water opens and discharges fresh water? Is this possible? Is this too long of a run for the water from the unit to keep enough pressure? Any ideas would be great. Thanks Guys
I have parts on order for this as I type. My R/O unit is under kitchen sink about 25' away from tank. No walls just open space(dining/LR)
Hook up will be a shut off valve for the RO unit (LFS ordered it out of their catalog)(I can get you info if you need it), P/H, 30' line, auto top off contoller(still deciding this one, DIY or something like flowers). RO unit and shut off will sit under cabinet, fill up a large plastic container-trash can, file box, etc..what ever fits. Shut off valve will keep this full. P/H in container piped to sump/tank, along with a pair of wires. The wires will go to the float switch in sump. The other end to an extension cord. The P/h will plug into this. So when sump needs water it will drop the float valve, complete the electrical circuit with the ext. cord and turn on P/H. Once float switch raises circuit will break and P/h off. R/O will fill as its level lowers through out day.
