5.8 Suspension of water piping
Suspend the water piping at certain points and prevent the water piping from being in direct
contact with the building: walls, ceilings, etc…
If there is direct contact between pipes, abnormal sound may occur due to the vibration of the
piping. Pay special attention in cases of short piping lengths.
Do not fix the water pipes directly with the metal fittings (piping may expand and contract).
Some examples for suspension method are shown below.
