Why Every Home Needs A Pressure Reducing Valve (PRV): A Comprehensive Guide For Safety And Complianc

Updated: Mar 2

Understanding the Pressure Reducing Valve (PRV)​

What is a PRV? A Pressure Reducing Valve (PRV) is a critical component in your home’s plumbing system, designed to regulate water pressure and prevent potential damage.


The Urgent Need for PRVs: Safety, Compliance, and Insurance Implications VBA Regulations and Home Safety The Victorian Building Authority (VBA) requires the installation of PRVs on any water line worked on by plumbers where the pressure exceeds 500 KPA, a common scenario in Melbourne homes.


Startling Insurance Data Suncorp’s statistics reveal that burst flexi pipes account for one in 10 of their water damage claims, emphasising the risks of high water pressure.


The Risks of Delay: Time, Holidays, and Home Maintenance

Rapid Damage from Burst Pipes

A burst pipe can flood a home within 24 hours, causing extensive damage in a short time.


Holiday Vulnerability Most claims occur when people are away for holidays, like Easter and Christmas, leaving homes unattended and more susceptible to unnoticed damage.


Mandatory PRVs and Flexible Hose Lifespan Many homeowners are unaware that PRVs are mandatory when plumbing work has been done. Additionally, flexible hoses, a common plumbing component, have a maximum lifespan of only 5 years.


Insurance Policy Requirements Most insurance policies require homeowners to keep their property in working order, including ensuring that fittings are not showing signs of wear and tear. Failure to comply can impact insurance claims.


Benefits of Having a PRV Protects Plumbing Fixtures: PRVs safeguard your plumbing system from the damaging effects of high water pressure.


Reduces Water Wastage: Lower pressure means less water use and lower bills.

Prevents Leaks and Bursts: Mitigates the risk of plumbing emergencies that can lead to significant property damage.


Ensures Consistent Water Pressure: Essential for the efficient operation of household appliances.


Identifying the Need for a PRV Excessive Water Pressure: Symptoms like forceful water flow can indicate the need for a PRV.

In Older Homes: Check for the absence of a PRV, especially in older properties.

After Plumbing Renovations: Consider a PRV as a vital part of any major plumbing work.


FAQ’S – PRV Frequently Asked Questions


Will my shower and Tap water pressure be noticeably reduced if I install a PRV?

Typically we don’t find that customers notice any reduction in water pressure as typically many fixtures are made to operate at 500KPA and any additional water pressure only puts pressure on the fixture and typically doesn’t increase the water usage experience.


Is it true that a PRV is required for Fixture Warranties?

Yes, many (in fact most) Taps, Toilets, and other fixtures require a PRV limited to 500kpa to be installed in order to maintain the warranty.
