There are Australian Standards in place to protect you and your property from potential damage that might occur. Extra precautions are taken by making every new build (or extension work at a home) install a pressure limiting valve. With a PLV, the water pressure is capped at 500kpa thus reducing the strain put on your plumbing system.

There are some key signs to look out for that may be a warning that you are in need of a water pressure limiting valve or a replacement when your pressure limiting valve is leaking. These include (but are not limited to):

Hot water systems are not made with a PLV but they do certainly benefit from the installation of one to the plumbing at your water meter assemblies. As you can imagine, too much pressure on your hot water system could cause damage to it (as well as many other appliances for that matter). As the high volume and strength of the water is on the search for somewhere to go, if it finds other appliances that are not cut out for a water supply above 500kpa, it may find a weakness and cause unnecessary damage. This is why the installation of PLVs are so important.
