Re: The cheapest RO membrane on market

I think you misunderstand how a watermaker and reverse osmosis works. Nothing on the pump side is getting through the RO membrane. Nothing on even the best pumps is food service grade. You can push raw sewage through the cheapest pumps and an RO membrane and get safe water out of it.

It might make you feel better to think you have food service grade components, and that they are providing you higher quality water, but the facts are neither of those are true.

FWIW, the Karcher pumps used in most of these cheap systems are not cheap steel. They aren't even metal of any type.

The only downsides to the cheap systems are breakdowns and lifespan. Water quality and safety is the same when they are working.
