Repair
-
always let someone know when you are going to work under a house
-
attach all loose pipework to framing at 300–400 mm centres with proprietary clips or brackets. Options include hanging brackets (for below framing) and standoff brackets (for alongside framing)
-
install insulating sleeves to all hot water pipes, and to cold water pipes in areas subject to frost/freezing. Use purpose-made, preformed insulation a minimum 13 mm thick

if water hammer is a problem (where pressure surges through a water pipe cause vibrations that make a hammering sound), clip pipes with rubber insulated clips or clip over the pipe insulation and fix pipework rigidly to prevent movement
