I had a couple of question about the auto top off system i am setting up. Do i need to keep the ro water flowing in the plastic tank and do i need a heater in it. I have a maxi jet pump to fill the tank.
Heater would work. Not neccessary to have the RO constant filling. You can check it every few days. Or to keep it more maintenance free, you run the RO to it with a shut off flow valve.
