This goes back to the old question "What weighs more, a pound of lead or a pound of feathers?"
Just another thought on head
pressure and watermakers. Such small pressure as 14lbs exerted on a SW membrane ("shouldn't") but would be more likely to produce osmosis
, not reverse osmois. It's why it's important to be careful on a WM installation
when running a product water
supply line to a tank where the feed is installed at the tank. It would not be the first time a boat owner, after making water
, has left the product supply valve open on a improperly installed line and had treated water from the tank ruin the membrane.
