Grundfos STP-2.0 B Positive Head Shower Pump

The Grundfos STP 2.0 Bar Shower Pump is a WRAS-approved booster pump that can be installed between the water pipes in your home. It ensures that the water pressure is increased while you are showering and/or turning on your washbasin tap. This means you can enjoy a stronger stream of water in both cases. The pump provides a maximum pressure of 2 bar. This model pump has a positive head, which means that the water flow to the device is always natural. The water source (usually a cold water tank) to which it is connected is situated at least 1 metre above the pump. Owing to the run-off created from the tank to the pump, the water flows into the pump as a result of gravity. Because the pump does not need to draw the water in first, it therefore operates far more efficiently than, for example, a pump with a negative head.  Another major advantage is that, in this situation, air is less likely to build up in the system. Air is not good for the pump, as sucking in air will prevent the pump
