Water piper knocking - is this 'water hammer'
The pipes in the loft are knocking so much that it wakes me in the morning
(when the heathing/water come on). Is this 'water hammer'? What's the best solution to this? Thanks. -- |

Thanks. -- Most likely not water hammer. WH shows usually when a tap or ball valve shuts down. Your heating should not be drawing any water. More likely some pipework to your central heating is in the loft and is rubbing against a joist or other object and the expansion is making the knocking noise. Cure? trace the pipes and place lagging around the pipes where they rub against anything. My CH pipes are rubbing on the joists under my floorboards in the bedroom. One hell of a racket when the system warms up in the morning. |

The expansion/contraction can create infurriating noise as the pipe periodically 'jolts' through the fixing. Like to know the best compromise for this myself, the previous owner thought that strategically placed socks were the answer. -- Mike W |

I wrapped mine with the 'carpet felt' type pipe insulation where they pass through joists etc. to forestall this problem. Fastening heating pipes down may make it worse if they haven't room to expand. Cheers all. Will get on it. -- |
