| MINIMUM SUPPLY PRESSURE | |||||||||||||||||
| System design and pump selection is critical when water heaters are connected to a low pressure water supply. Refer to the table below for minimum pressure equirements for Grundfos UPS series pumps. Minimum pressure requirements for TP series pumps depend on system characteristics and need to be calculated. Contact your pump supplier for details. | |||||||||||||||||
