In 2015, I installed a Grundfos BMQE booster pump to raise my house water pressure. I have about 6-8 psi at the inlet side supplied from well water holding tanks (located uphill and about 250 feet from the house) that is pressurized to 60 psi. System operation has been flawless now for 2 years. This pump is great; easy install, variable speed without any surge, very short run cycles (only 30-45 seconds per cycle), the outlet pressure can be increased/deceased at a touch of a button (up to 100psi), fairly low noise, Grundfos quality, etc., etc. Negatives are: they're expensive, and that's about it.

Here's the problem - they don't make'm no 'more. And, I would like one for another house install here on the property. I went online to order one and just found out this out. I would appreciate recommendations any of y'all may have for a comparable variable speed booster pumps, and/or, recommended variable speed controller and pump combinations. 

Thanks

    Yep, that's the baby.

    However, when you click to send it to the shopping cart, they inform you that the unit is not inventoried and they don't know when it will be.  :/

    Update: I kept searching online and found a retailer that still had a couple of the Grundfos BMQE pumps and controllers in stock. Although I may have warranty issues in the future, right now I'm a happy camper.  :):)
