Will this pump work on a storage tank and supply enough pressure for 3/2 house’s pressure needs?

Asked by: Mark
This product will act as a shallow well pump. It will pull water out of a storage tank and pump it. The product works at a constant pressure of 40 PSI. Meaning it will add 40 PSI to whatever the inlet pressure is. It the water coming into my house was at 30 PSI, this unit will add 40. Making the final pressure 70 PSI. However pressure is invisible. People call me all the time and say things like, " I have good pressure in my sink but its bad in my shower." That is wrong and they are confused. You can not see pressure. Pressure is tested with a gauge. What you can see is volume and velocity. Both are confused with pressure all the time. So the question you want to know is will this unit pump enough volume of water. First that would depend on you expectation. Do you expect three people to be able to shower at the same time. With out knowing your expectation I can't answer that. But I can tell you how to answer it. Once you determine what you want for a flow rate capacity in Gallons per minute. You can look at the pump curve that is located on the specification sheet. That sheet is on the product listing page on the Home Depot web site under ":Info and Guides. All pumps have a pump curve or graph. On one axis is height and on the other is flow rate. Once you measure the height you will be lifting the water the graph will illustrate how much water the unit will pump at that height. With that said i can tell you that I use on of these at my cottage. I use it to pull water out of the lake and supply the camp. So it is only lifting the water a few feet. It works great. However if it was supplying my neighbor as well, i would imagine I would notice a decrease in flow if they turned on there shower when i was taking one.

Customer Reviews

MQ3-35 3/4 HP 115-Volt Pressure Boosting Pump is rated 3.3 out of 5 by 6.
Rated 1 out of 5 by from Buyer Beware - Bad Pump! Original MQ-35 pump lasted 8+ years, was a great pump! Replacement lasted only 4 months of light residential duty than started leaking. 3rd replacement leaked within 48 hours. Must have had a bad run on shaft seals. Can't keep installing this pump until they resolve the issue. Customer service is limited, website requires email and than wait for response, unacceptable. Can't currently recommend this product, unfortunately had to go with another manufacturer.

Rated 5 out of 5 by from Works Great! I have been using these pumps for about 8 years now and they seem to be the most dependable for the price. Great product and easy to install. In the past i have changed things around and needed replacement parts and it was easy to get them though the manufacturer. We have one pump that feeds our entire house with no issues, the rest of our applications are in the workplace and are running at high demand with no issues at all. Pricing at the Home Depot was cheaper then our commercial account at the local plumbing supply chain. This is a great product, and i highly recommend it.

Rated 5 out of 5 by from Awesome pump! VERY easy install! No plumber needed with the help of a couple 1 inch shark bite metal water hoses with 1 inch female threaded ends!

Rated 1 out of 5 by from this is junk only lasted three weeks before it started leaking I paid over 700 hunderd dollars for this pump that only lasted 3 weeks then it started leaking out of the shaft seal just to find out this is a major proplem with these pumps

Rated 4 out of 5 by from Paid new for used I opened the carton to find the unit was previously used. The owners manual had notes in the margins and areas hi-lited. The unit works ok. I just was very disappointed to pay full price for a unit that obviously was not new.
