2. Is this referring to the feed water or a re-pressurization pump after the RO system?
Response: Feed water high pressure pump.
3. Can you provide any information regarding the feedwater source or its characteristics? TDS levels, mineral content, etc.?
Response: Feed water source is 100% raw sea water with origin from the southeastern Gulf of Mexico with the characteristics common to such.
