I think he meant ASOV (Automatic Shut Off Valve)... Shuts unit off automatically when resevoir is full or back pressure is high enough.

AVOS, that's the Weather stations we put on ships. Too many acronyms.

Yes meant ASOV

and if you do need to order a membrane, seems the 75g might be the better deal.

So, i should buy a 70 gpd? Are all membrane universal? do i need to buy a flow restrictor also? is a pump booster a good idea also?

Yes, buy 75 gpd membrane and restrictor. Restrictor is the key to keep flow at rated level for the membrane. Booster pump is a good idea if the pressure of your water supply is not adequate. I would start without it, save some $$$ . Measure the production level of your setup and see how far behind gpd you are.
