              We used this to increase our water pressure in our home. Well, it works great and should have installed this when we built the house.
              Good price and quality pump.

                          This pump delivered exactly as described. After many years of 15 lbs. of city water pressure it is great to have 50+ lbs. Installation was easy and the only problem was the need to retape the threaded fitting on the suction line. The pump runs quiet and I used pex tubing on the inlet and outlet to help with any vibration noise. I have the pump on line for about 2 weeks now and I am very pleased with it.

                          The pump does boost the water pressure. The pump is easy to install. The pump is very quite. The pump IS NOT able to be regulated as far as I can find out. Tried support and have not heard back in a week. Pump comes on at 35 psi and shuts off at 85 psi so at first you will get a dip in pressure until it turns back on then it pumps to 85 even if you shut it off early. My first pump worked flawlessly just did not last as long as I had hoped. 6 years of residential use.

                          Comments about MQ3-35 Pressure Boosting Pump (115V):

                          This is being used as a booster pump on my city water. My home reaches the required water pressure once during the day, so my town refuses to give me a pump. This meets my needs. This is my third Grundfos pump. I know that there are replacement parts that can be purchased for this pump, so perhaps I could repair the previous pumps which I still have. The problem is that I have no way of knowing which parts would need to be replaced since I have not been able to find any troubleshooting information that would be helpful for me. I would like to see Grundfos offer information for pump repair and not just to continue to require that I purchase new pumps. My last pump was good for 9 years. I would expect more out of a pump than that, but many people had a lot less years of service from their pumps. PexSupply was awesome with their pricing and shipping. I received my pump very quickly and the pump was well protected and did not show any damage in the shipping process. I would shop with PexSupply again in the future.

                          Easy to install, very solidly built, quiet. Functions as advertised. However the plastic 3/4" NPT fittings were small, and it was very difficult to get them to seal. It took 2 sets of PVC valves and a lot of pipe dope to stop the leaks. Should have a union on both the inlet and outlet. Had to cut the pipe to get pump out to reseal the connections.

                          I am using this pump to correct low water pressure and flow from the municiple source (20psi). This pump has fixed all of our water woes and is very quiet. I was using a convertible well pump before and the noise was terrible.

                              These pumps have fixed uplift of approx. 45lbs. You can put a pressure reduction valve on the input side to control input pressure. You can also put one on the output side but back pressure may be an issue. In put side is easy and put a pressure gauge on out put side. Pressure gauge 10.00 and reduction valve will run from 70.00 to 110.00 at Home Depot depending on 3/4 or 1" size.

                              A standard residential system will have a system pressure of about 60psi. Every system is different. The Max pressure for this unit is 109 psi.

                            Q:

                            I’m on town water supply but at the very end of the line with very low water pressure and the supply volume is 45 gal/hr. Would the supply volume be enough for the Grundfos MQ3-35/115v pump to work or would I need a reservoir tank for the pump to draw from?

                              The MQ has a Maximum inlet pressure of about 40psi. It is recommended to put a pressure reducing valve before the pump so that the pump is always working off of the same incoming pressure. It is also recommended to set the Pressure Reducing Valve at about 25psi - 30psi. As for the flow rate, it sounds like you may want to put a tank in. That pump will move close to 11gpm - 16gpm. That supply would not keep up with the MQ.

                              Provided that you are not at high altitude, the MQ3-45 is capable of pulling water from the MAXIMUM vertical lift of 26 feet. Obviously, you would want to be less than that for normal operation. This is assuming that the pump is primed, i.e., filled with water as described in the manual. Cavitation is not related to this. If the inlet pipe is the same diameter as the inlet to the pump, cavitation should not be a problem.
