Comments about MQ3-45 Pressure Boosting Pump (230V):
This was a replacement for our first unit, which lasted about 7 years. We use it to supply our home. The prior unit worked well in heat and cold. Dealing with SupplyHouse was easy and the item arrived on time as expected.
Bottom Line Yes, I would recommend this to a friend

Lives up to its claims!
from Jacksonville, FL
As this pump is used to bring water into the house from the aerator it is essential that the water flow is consistent & the Grundfos does just that!

I have 2 of these at my ranch house. One for home and other for stock. They have done well until some grand kids left the water on and ran storage tank dry. The pump locked up and will not turn even though it is supposed to have automatic protection against running dry. The new one had instructions on how to manually unfreeze one. I have not tried that yet, so it may still be good. Other than that, very simple and easy to install.

from Wimberley, TX
Works great with my rainwater catchment system at a price that beats the competition. Plus, customer service quickly resolved a screw up with my initial order and got the right pump to me asap.
