  1. Increases ro/di performance Review by Jonathan
    Product Rating:

    I was burning through DI resin, so I decided to add the Aquatec Booster pump kit. Solved all my problems - took my water pressure from 45psi to 80psi. Output went from a few drips to a steady stream and my DI resin is lasting much longer now. If you are on the fence like I was --- DO IT! - well worth the $ (Posted on 5/19/2019)

  2. Universal pressure increases Review by RP709
    Product Rating:

    My RODI system also makes drinking water and ice not just tank water, this booster pump increases pressure and output across all devices. All you need to install it is 4 mounting screws and a tubing cutter. Mount the pump near the input/ output of your system and within reach of an outlet for the transformer. Install the push (Guest) fittings in the pump, cut the input water line for your RODI unit (make sure to turn the water off and depressurize the lines first) and insert into the fittings flow is right to left indicated by the arrows on top of the pump. Your basically putting the pump inline between the water supply and the RODI unit. Next connect the pressure switch to the pump and power supply connectors, cut the product water output line and connect each side to the pressure switch (flow direction does not matter here). Turn the water on and do a quick leak check, plug in the transformer and open a product water device (float switch/ valve/etc.) and your making water, that's about it. Total installation time of about 10 minutes, almost doubled my water pressure, I wish I had installed one sooner! (Posted on 12/12/2018)

  3. Nice pump Review by Dino
    Product Rating:

    Love the pump. Same pump that Spectrapure sells however Aqua Cave sells it cheaper AND the switch comes with the unit unlike spectrapures kit! (Posted on 4/12/2018)

  4. Great Addition For RO/DI System Review by Jason
    Product Rating:

    Allows your RO/DI system to run at the recommended PSI instead of whatever your water pressure is from the city. Shutdown switch works great. Setup and mounting the pump is simple. (Posted on 12/3/2016)

  5. Great Pump Review by Jay

    Fairly quiet and works great! I am on well water and my pressure is about 30psi. The pump increased the pressure to about 120psi. It was extremely easy to hook up and works like a charm. When I had questions in the past, I have found Aqua Cave's staff extremely helpful. (Posted on 10/19/2011)

  6. Great pump Review by RLB1130

    Works great but directions are horrible. Took forever to find instructions to use setup with pressure tank and ASV. Best advice replace existing auto shut off with a solenoid. Getting the ASV in tune with the pressure switch is no easy chore. By placing pressure switch near tank (after ASV)I have inlet pressure to membrane of 80 psi and tank pressure of 60 psi with the stock pump/pressure switch settings. Had to get a solenoid as I couldnt get the ASV to work with the pressure switch and pump would not shut off. If you place switch immediately after the pump you will only get 60 psi max pressure into the membrane.. (Posted on 9/26/2011)

  7. Works great Review by Deeber

    The product works great but there are a few problems. First no manual, this pump is not hard to figure out but if you need to lower the pump pressure it would be nice to have a manual to tell you how to do this (1/16" Allen wrench needed to turn the screw on top of unit) (Posted on 11/9/2010)

  8. Booster pump GREATLY enhances RO performance Review by Jungle John

    RO machines run like a snail until a booster pump is employed. Aquatec makes the best in the business. My system produces water with lower TDSs at a rate more than twice as fast as prior to plumbing the Aquatec pump. Highly recommended for all RO users. Remember that 99.9% of all marine life agree: Nothing but RO water for me, please! (Posted on 3/11/2009)

  9. The best pump I ever had for my reverse osmosis system. Review by sally

    with great pleasure and confidence.
