    1. Great Pump

      I installed this pump in a 1,000 gallon rain harvesting tank used to water our garden. It is a great pump. Easy to install and I was very surprised at the pressure it has. I would highly recommend. on 27th Aug 2018

    2. Grundfos SBA-3-45-AW Automatic Pump with Floating Extractor

      Received pump promptly from RainBrothers. Set it up with 6 feet of flexable1-inch high pressure braided PVC Tubing. The setup pictures that came with the pump were helpful along with the rain cistern diagram that Jonathan from Rain Brothers emailed me. After all the plumbing connections were made, I lowered the pump into my cistern with a rope. Tention on the rope holds the pump upright to keep it from falling over in the cistern. I plugged the pump electric cord into an outlet and it pumped to fill the line and then shut off. The Grundfos automatically turns on when the water valve is open and shuts off when it is closed. The pump works perfectly and I could not be happier with this purchase. on 16th May 2018

    3. Incredible pump!

      When I got everything hoked up, the only failures were my connections, not the pump. (Shark Bites aren't supposed to fail, right?) It has provided constant water with great pressure, silently, since I installed it. And it was turn-key. I didn't need to set up a pump and a bladder tank. It is all in one housing, in a submersible unit!

      Sincerely, this pump was an answer to a prayer.

      And many thanks to Johnathan at Rain Brothers who answered all of my dumb questions as if they were well though out and well reasoned.

    4. Great Pump

      This pump is excellent. It worked from the first time it plugged in. It is quiet. The cistern it is in is slightly uphill of the discharge, so it has a lot of pressure and volume. It is more than enough for a family of 6 with 3 bathrooms. I plumbed it into 1" PVC Sch. 40. It does need tied up, i had to put in a threaded eye bolt and hang it 1/2" off the bottom as it can tip over. I used 1" fiber reinforced vinyl hose to go from the pump discharge to a bulkhead fitting. on 9th Apr 2018

    5. great plug and play pump, but it floats

      I installed this pump inside a 1,000 gal above-ground metal rain cistern, and it works beautifully. So nice to spend a day cleaning out a cistern, installing a system of electrical supply, and plumbing a pump to the outlet, to find it all works on the first try. Yay! And it really creates great water pressure. I have it linked to a 1” outlet, and when I tested water pressure with a hose, it shot out 15’ easily with no nozzle.

      My only complaint/concern is that it tipped over and floated as soon as it turned on. We end up tying a line from the top handle of the pump to the top of the cistern to keep it upright. I wish I could attach it to a weighted donut at the bottom. It didn’t seem smart to let it roll and float around.

    6. Excellent product

      I can't say enough about this pump. I plumbed it into my water system, plugged into 110VAC and it works as advertised - great. No more pressure tank, no more pressure switch and no more clogged filters with the floating suction. Fantastic product

    In this video, we detail how to install our new plug-and-play Grundfos cistern pump.
