Installing a Booster Pump for RO/DI System

My water pressure was not high enough for a dual chamber RO/DI system so I am adding a booster pump to get the pressure between 65 and 80 PSI. I purchased the pump that came with a pressure cutoff switch from Bulk Reef Supply.com. Booster Pump and Pressure Cutoff Valve from BulkReefSupply.com. www.bulkreefsupply.com/1-4-aquatec-8800-booster-pump-kit.html
