Which pump should I buy? Selecting the correct pump to connect to your ABOVE GROUND tank system is pretty easy as it depends on how much water you require and what you are going to use the water for. The following recommendations are made based on our knowledge and over 30-years of experience. We strongly recommend that you purchase a stainless steel pump when the water is going to be used in the washing machine, toilets, or for drinking. The "Yes" selections in the table are all suitable for the detailed task and the "Yes" in blue is the recommended option as it is the most suitable and will provide excellent value for money.

Watermark Approved Components for Automatic Valve Switching between Town Mains and a Grundfos Automatic Pressure Pump
This is everything that your plumber will require to assemble an "Automatic Town Tank Switching" unit. The unit is installed and connected to the town mains water supply and to the Grundfos pump drawing water from your tank and the house. When you have rainwater in your tank, the Grundfos CH2-40-BK pump (or larger) will automatically use tank water and, if the tank runs out of water, the town mains water will automatically flow instead of the pumped water. In the event of a power failure, town mains water flows automatically. We supply this equipment as individual "Watermark Approved" components so that your licensed plumber can assemble them and install the unit to comply with all regulations. "Back flow prevention" is carried out by the dual check valves and these also prevent town mains entering your tank and, tank water entering the mains. For further details and a larger image, click on the "information" button to the right.
