This build-up of debris can prevent the pressure relief valve from seating properly. This can stop the water flowing through the boiler pipe as it should do so. This issue should be fixed or replaced as soon as the issue is identified to avoid a disastrous incident.

When it comes to the safe function of a boiler, a pressure relief valve is hugely important. For a boiler to function effectively and to the best of its ability, it is important that the pressure relief valve is maintained on a regular basis. But what does the pressure relief valve do on a boiler that makes it so crucially important? Leading pressure control equipment suppliers, Fluid Controls Ltd answer this and explore how to test pressure relief valves on boilers.

The main cause of blowout is pressure. Whether it’s poly fittings, PVC fittings or timers, whatever the component, if the pressure is too high for what it’s designed for, kaboom! Simply solve the problem with a pressure reducer & make it a brass one if it’s on your water supply.

These brass fixed pressure regulating valves are ideal for systems which require reduced & regulated pressure, like drip irrigation systems. For areas with high pressure.

So, the importance of regularly testing the pressure relief valve in a boiler has been defined. It is now important to understand how to test pressure relief valves on boilers. It is actually relatively simple and can be broken down into three simple steps.

There’s no best type of sprinkler, just better sprinklers for different applications. Gear Drives are better for large areas, over 5m. Pop-Ups are ideal for 1.5-5m & Micro sprays are excellent for anything under that.

The recommended timescale for carrying out maintenance and testing on a pressure relief valve is 6 months. Leakage is usually one of the main things to look for when understanding what causes a pressure relief valve to fail in a boiler. This is usually caused by a build-up of substances such as mineral salt, rust, or corrosion.

We definitely don’t recommend it. Typically, drip tube will deliver the water at a far slower rate that sprays. Because of this, if you were to have both on the same zone, the areas with drip would be left far drier than the areas with sprinkler coverage. If you do want to water some areas with drip & some with sprinklers, it can be done, but each will just need to be run on their own separate irrigation zones.

It is because of this reason, the maintenance of the pressure relief valve is so important. Should the pressure relief in your boiler fail, it can lead to catastrophic accidents within industrial settings.

Luckily the replacement unit was the same length as the old 2 to 1 reducer. So replacement was effected in 15 minutes. The new 500kPa pressure reducer exhibits a higher flow rate characteristic relative to the replaced unit. Supply and postage was prompt.

Even on a typical domestic system running on mains water a filter is still a good idea. In the event of a water main fault where rubbish does find it’s way down the line, a filter will protect the system from blockage and or failure. On systems operating off recycled water, like from a tank, a screen filter is mandatory. Debris like silt & dirt from recycled water is the most common cause of blockages of failures in irrigation systems.

Plastic pressure reducers can’t handle constant high pressure so the benefit with a brass pressure regulator is that you can put one on at the water connection for a drip irrigation system rather than one plastic pressure reducer on each zone.

Each sprinkler & nozzle will push out water at different rates, but the key factor is the flow rate of your water supply. Work that out with a simple timed bucket test. From there, you can work out how much water each sprinkler you’re looking at uses & work within your flow limit. For more information, check our Product Guides.

On a boiler, the pressure relief valve is one of the most important safety aspects. It is used to ensure that the build-up of intensive pressure within the boiler can be relieved in order to avoid catastrophic accidents. It works as an open-close feature: opening when the pressure has built up to dangerous levels and closing once normal pressure levels have been reached.

Drip tube is excellent in areas of rich dense soil where water spreads nicely throughout. Installed under mulch, the water is delivered with minimal evaporation & wastage, going direct to the root ball.

How to test pressure relief valve on boilers So, the importance of regularly testing the pressure relief valve in a boiler has been defined. It is now important to understand how to test pressure relief valves on boilers. It is actually relatively simple and can be broken down into three simple steps. Raise and lower the test lever – performing this several times will lift the brass stem it is fastened to. Look for water flowing through the pipe. If the water passes through as it should, then turn down the water pressure. If no water flows through or very little flows through, then there is an issue with the pressure relief valve that will either need fixing or replacing as soon as possible. As well as the above steps, there are also other components to look out for when testing a boiler’s pressure relief valve. They include: Pipe length – should be the same diameter as the exhaust valve port. Pipe material – needs to be heat resistant. Drainpipe direction – should travel slightly downhill and finish between 6 - 24 inches from the ground. Testing all of these components is extremely important for the correct function of your boiler.  Identifying these issues before they have the opportunity to escalate into a bigger problem makes it easier to find a solution, and maintain the high performance of your boiler moving forward.

As you install a system, it’s almost inevitable that small fragments of dirt will get into the pipe, for this reason you should always flush out the system before running it the first time. This can be done by leaving an open end at the farthest point of each irrigation zone & operating the zone for 15 or so seconds to flush it out. Then plug it up & you’re good to go! This can also be said for any other times dirt may have gotten into the system (eg: further irrigation repairs or a mains water supply fault).

These brass fixed pressure regulating valves are ideal for systems which require reduced & regulated pressure, like drip irrigation systems. For areas with high pressure.

No, drip tube isn’t simply holes punched into poly pipe. Inside each hole is an intricate dripper which delivers that water nice and evenly. Punching a hole will simply create an uncontrolled leak!
