Review on iSpring Reverse Osmosis PMP5 Water Booster by Justin Ferguson

My downhole pump pressure of 5psi is too low for the iSpring reverse osmosis system, so I had to shell out this expensive pump. Not only does it not include a power transformer, proper reverse osmosis pipe connections or a pressure switch, it doesn't even include instructions or screws to assemble it! In fact, there were no documents in the box at all. I don't even know if it's under warranty. For such an expensive part (compared to the rest of the system) just to bump it up to 5psi I am very frustrated that I have to figure out what parts I need for this installation, I have to make a trip to the hardware store (or wait for another shipment from Revain for non-Prime parts) and I'll have to wire it to the transformer myself as including the transformer, hardware, installation instructions and screws will probably only add $2 to the cost of making this item . I would happily pay $10 or $20 more if it was the full package. This really seems to be an afterthought by iSpring.
