This pump provides good pressure and GPH but there are many factors involved in choosing the right pump for your house. There are bigger pumps available and booster pressure pumps as well. The information provided on your situation is minimal at best making a precise answer not possible. See below for suggestions on other possible solutions.
Do I need to install a pressure relief valve to keep my tank and PVC piping from exploding in case the pressure switch fails and does not shut the pump off, or does the pump not create that much pressure?
