Most commercial building depend on indoor plumbing in some fashion, whether for the bathrooms or as an essential part of running a food service company. You probably don’t know much about how the plumbing in your commercial building operates, which is understandable since this is a highly specialized field of plumbing that require years of training. You’re probably not aware of a device called the booster pump, but for companies that use a high volume of water or have multiple floors in their buildings, this is a key device for keeping up water pressure throughout the plumbing. Buildings with four or more floors will probably require more than one booster pump.
