Here are a few pictures of similar systems and what the pump owners say about them. So, for pump longevity you need to use a control they don't recommend. Pump companies push what makes them the most money. Your installer and pump manufacturer will never mention these, and will try to make you think they are bad if you find out about them. Here is a booster pump that ran 53 years using a device similar to the CSV. Adding a simple Cycle Stop Valve before the pressure tank/pressure switch solves all the problems with cycling with a standard pressure tank system. The only problem with this old tried and true method is that the pump cycles on and off repeatedly. A regular pressure tank/pressure switch is the most reliable way to control any pump. It has a quiet motor and connects to the Grundfos GO app via built-in Bluetooth to make it highly customisable. SCALA2 has integrated speed control which allows maintaining perfect pressure in the taps. SCALA1 is a fully integrated, compact, self-priming water pressure and irrigation booster pump for domestic use. SCALA2 is a fully integrated, self-priming, compact pump designed for pressure boosting in domestic applications. Those "all-encompassing devices" like the MQ and Scalla are meant to "sound" attractive and be replaced often, which means more of your money going to the installer and pump manufacturer. Suitable for: Residential groundwater intake. Your installer is recommending what is best for him, which is the worst thing for you. Please note that this will be used to boost city pressure and not a well. Ideally the pump will be an all-encompassing device without the need to install additional items to get the pressure up and steady. The Grundfos CMBE 1-44 seems more robust but that's a lot more pricey.ĭoes anyone have a recommendation on a pump that can boost my 55psi to about 80psi? My budget is right around $1000 for the device. The reviews I read on Scala2 frighten me because they seem to break down and leak within about a year. I'm working with a plumber who is recommending I install a Grundfos Scala2 or MQ3-45 pumps. Even with CA limits these valves are not getting enough pressure so the water basically just pours out and doesn't push out.Īll the neighbors are experiencing basically the same issue and they mostly have installed booster pumps. The shower valves on the 2nd floor really need more pressure (They're brand new Brizo/Delta valves limited to CA limits). I live on a hill in Southern California and the highest my city pressure gets is 55.
