2nd Top Tip....Do not drink RO water that is older than 24hrs...If chilled to 4oC you can keep it for 48hrs. This is because all the chemicals that keep the water safe to drink have been removed. A breading ground for bacteria.

I reall ydont recommend turning it on and off...This will just damage the membrane and allow (dirty) water through. Always test with a quality TDS meter. TDS meters are available on line and are quite cheap.
Before I retired from working offshore, I used to work a lot with big industrial water RO units i.e. maintenance I was always told that as long as membranes were kept wet that this was ok. so if you were to block the inlet and outlet closed with water within the system all would be OK. Upon restarting they would need to be ran for a while before using the water
