Installation: FAQs
How do you find out what the system maximum operating pressure is?
One way is to measure the supply pressure at a tap directly supplied from the mains at a time when there is little demand, such as at night.
Please note:
- This will not take into consideration any transient or surge pressures which may be generated within the system. For example water hammer resulting from the rapid closure of a valve within the system.
- Water fittings must be able of accommodating 1½ times the maximum operating pressure.
