When your mains water supply has inadequate pressure to service the demands of your building(s), installing a water booster set will give you the pressure and volume of water supply you need. Water booster sets are required in large residential buildings and most large commercial buildings like factories, industrial units, offices, hospitals etc. Nowadays, there are increasing numbers of smaller residential properties that suffer from low pressure mains water supply so a small water booster pump or water boooster set can be installed – even in the smallest of spaces.
