Question: Does it require a minimum input pressure to activate? Other models would not start if the input pressure is higher than the threshold.
Document: Nothing has changed with the units size/shape... Why pay to reconfigure all of this. I've come to the realization that I'll probably have to replace this every three years at a cost of $450. The upside is going from 30 psi, our water pressure from the street, to 65 psi. The difference between day and night. Without the prv it would be much higher, dangerously high. All things considered, that's the cost of having good water pressure.
Had just moved into a new home and the water pressure at the kitchen sink was just awful! Went to the City and they came out to check. I watched them take the pipe from the main and put a pressure gauge on to check. 42PSI. Their explaination was my home was near the end of the run and that was the best it would do! Bought the Grundfos booster pump and the pressure boosted to 110 pounds!
I built a house 7 years ago and needed to boost my water pressure because we live on a hill. This pump came highly recommended from a local pump dealer. I bought the 240V model because it was supposed to run more efficiently and last longer. At a price point of almost $500, I believed that it would last a long time. Wrong!! Just out of warranty it failed. I thought, darn the bad luck and bought another one. It just failed too.
Grundfos is a premier pump manufacturer and this model is no exception. Well-designed, well-engineered, well-constructed, EVERYTHING you need for a well!!! For decades I used the old tried-and-true bladder tank and cast iron pump with a capacitor that would go out every few years (we have very undependable electricity in our area that is hard on such things).
I have just ordered my third Grundfos MQ3-45 in three years. Each of the first two failed. The first blew a gasket and flooded my basement. In its second year, the replacement pump simply refused to start up, repeatedly blowing the circuit breaker. Reflecting my hopes rather than my experience, the third one is to be installed this week.
The Grundfos MQ is a good pump. My plumber installed one for me almost three years ago and it just died. Seems to be inline with what I've read from other sites. While it worked, it worked well and quietly, I just thought that it would have lasted a bit longer. Grundfos' website and all owner's manuals are just about worthless as far as answering simple questions and there's no phone support at all. Now I'll shock you with this, I'm buying another.
If you need a pressure pump buy this one.
This pump delivers all the water pressure that I need, and is a much better one than I had in the past.
This item was just what we needed for our Water System. The installation went very easy. We now have sufficient water pressure and volume. The pump is very quiet.
Super great and no trouble to date!Item being reviewedGrundfos MQ3-45 96860195 1 HP Pressure Booster Pump - 115 Volt
