RO feed- Gravity flow

[coach]

Hi people. I’m just getting my homebuilt RO set up. So my sap tank is currently 2 feet higher than my procon pump, which is a 240 gph pump. Ran out of funds, so don’t have a feed pump. I do have a valve for recirculating, so I will be recirculating my concentrate directly back to the pump. So I’m estimating there will be a 1 gpm feed coming from the tank (gravity flow). So my question is: will I be fine with gravity flow?

Procon will work without a feed pump. Just make sure the line you have feeding to it is large enough to give it the volume it needs and you should be fine.
