The recent weather disruptions in New Zealand has cost thousands of dollars and hugely disruptive to everyone. Even though the these were mother nature causing havoc having a valve failure is just as critical to your water supply!
This is why you would want to consider having your Pressure Reducing/Sustaining Valves (PRVs) checked annually.
In the world of industrial water systems, Pressure Reducing/Sustaining Valves (PRVs) are one of those bits of kit that quietly do their job—until they don’t. And when they fail, the fallout can be messy, expensive, and potentially dangerous.
In New Zealand, where water supply and infrastructure are under constant pressure (literally and figuratively), it’s more important than ever to stay on top of your valve maintenance. Getting your PRVs checked and serviced at least once a year isn’t just a nice-to-have—it’s good practice and often essential to keep things running smoothly.
So, What Exactly Does a PRV Do?
A Pressure Reducing/Sustaining Valve is designed to do one thing really well: control and lower the incoming water pressure to a safe, usable level downstream. In industrial settings, this helps protect pipework, pumps, and other sensitive equipment from being over-pressurised.
Whether you’re running a manufacturing plant, a processing facility, or a large-scale irrigation system, your PRVs are playing a key role in keeping operations safe and consistent.
Why Annual PRV Maintenance Matters
✅ Avoid Major System Failures
When a PRV fails or gets stuck, it can cause downstream pressure spikes that damage equipment or cause blowouts. This can lead to unexpected downtime—or worse, health and safety incidents.
✅ Keep on Top of Compliance
Depending on your industry, regular PRV checks may be required for safety or insurance purposes. Annual servicing helps you stay compliant with workplace safety regs and ensures your system is up to standard.
✅ Protect Your Investment
Your pumps, filters, meters, and pipework aren’t cheap. Keeping your PRVs in good nick helps extend the lifespan of this gear by preventing pressure-related wear and tear.
✅ Improve Efficiency
A PRV that’s not operating properly can cause pressure fluctuations and reduce flow efficiency. In a high-demand industrial setting, even small inefficiencies can add up to big costs over time—in both energy and water usage.
✅ Prevent Costly Downtime
A failed PRV can mean shutting down part (or all) of your system while it’s fixed. A quick annual check helps catch small issues before they become major headaches.
What’s Involved in a PRV Service?
A standard annual check by a qualified technician usually includes:
- A visual inspection for corrosion, leaks, or damage
- Checking the set pressure and verifying it’s holding steady
- Internal cleaning or replacing worn components
- Testing for performance under load
- Calibration if required
- Checking upstream/downstream filters, strainers, and isolation valves
Pro tip: Always make sure the person doing your PRV checks is experienced with industrial systems. These aren’t household plumbing jobs—they need someone who knows their way around commercial gear.
Don’t Wait for Something to Go Wrong
Too often, PRVs are a case of “out of sight, out of mind”—until a problem pops up. And by then, the damage is often already done.
Booking in an annual service is a simple step that can save time, money, and a lot of hassle. If it’s been a while since yours were checked, now’s a good time to get back on track.
