This home in Regency Villas (御墅花园), Changning, Shanghai was recently completely renovated. To meet the owner’s requirements for clean, safe and soft water, Raylient installed an Aquasana EQ-600C whole house water filter and Aquasana EQ-AST-WH water softener.
For many years Regency Villas has a lower than normal water pressure. To resolve this problem and provide the home with a comfortable, stable water pressure, a Grundfos CM3-3 booster pump was installed.
Many times we are asked “should a water pressure boosting pump should be installed before or after a whole house filter?”. In almost all cases the pump should be installed after the filter system. If there is a sudden rise in the water pressure coming into the house, installing the pump before the system may cause a pressure spike that could damage a filter system (or softener, or UV system, etc). If the pump is placed after the system, a potential pressure spike will safety be distributed throughout the entire home’s plumbing system.
