The pump only increases the water pressure by about 10psi over my supply pressure of 40psi. I had to relocate the line to the reverse osmosis manometer to get an accurate reading because if the installation instructions were followed exactly the manometer would stay in front of the line coming out of the pump, not behind it so it wouldn't register. The line pressure delivered by the pump is accurate. After being moved, the gauge now vibrates quite severely with the pump running, so I would expect it to wear out fairly quickly, in addition to the pump not delivering the stated pressure. Second, since I have a DI stage downstream of the diaphragms and the manual allows it, I have the low pressure side entering and exiting the pump after the line exits the DI stage between that stage and the float valve with the required (but not into a (supplied) check valve between the outlet line on the direct injection stage and the inlet line on the low pressure side of the Buddie Booster. With the unit installed this way, the pump will turn off when the float valve stops the filtered Water BUT the sewage continues to flow and the pump cycles on and off about every minute or two, which I believe means it is actually trying to backwash the membranes and then shut off due to back pressure from the float valve, eventually causing it to rupture of the pump and probably led to an expensive reverse osmosis membrane I had to pre de install a ball valve on the raw water inlet to shut off the flow and activate the vacuum cutoff I don't want this to happen until I try to figure out a way to get the unit to do what it's advertised to do. In the meantime, based on the issues I'm seeing at the moment, the device isn't even close to worth the money I paid for it.
