How to change the pressure relief valve on a boiler

Make sure you’ve ruled out any more potential causes for why your pressure relief valve isn’t working before replacing the boiler pressure relief valve on your home heating system. The most accessible approach is to have a qualified service expert visit your home. They will help you to identify the problem and carry out the necessary repairs. Do not assume that the pressure release valve is not functioning correctly merely because water is leaking from it. Still wondering about how a Vaillant pressure relief valve replacement is done? Then continue reading.

If, for instance, the expansion tank in your system fails and results in excessively high pressure, the pressure relief valve will open to release pressure from the system. This doesn’t imply that the pressure relief valve is damaged. It indicates that it functioned as intended to safeguard your safety and the safety of your boiler. A broken fill valve or a leaking coil are two more factors that can contribute to high pressure in your system. You should have a boiler service specialist thoroughly inspect the system unless you are an expert in boiler repair. Also, look out for the range of other services we offer, such as our Boiler Installation London service.

When replacing a valve

Even if it does come out that the issue results from an outdated or damaged pressure relief valve, replacing the valve on a boiler is not as simple as plunging a clogged toilet. You must first get the correct replacement item at your neighbourhood hardware store. Ensure that the valve you buy will function correctly per the requirements of your boiler. Second, you must take safety measures to protect yourself and guard against further harm to your boiler. This entails shutting off the water supply and the electricity to the boiler and draining the system until no pressure is left. You should only attempt any boiler-related tasks on your own after that. Speaking of valves, check out one of our blogs where our team created one on how to fix a leaking boiler pressure relief valve.

Vaillant Ecotec Plus Diverter Valve Replacement

A combi boiler has a diverter valve that can be opened or shut to route hot water to radiators, faucets, or showerheads. System and traditional boilers do not have diverter valves since these boilers store hot water in a storage cylinder. This negates the necessity for the valve, which is only necessary for boilers that heat water as needed. When a specific hot water tap is activated, the combi boiler heats water, and a valve sends it directly to that tap rather than the house’s radiators or other taps. The combi boiler will activate the radiators like it does the heating. The diverter valve will deliver hot water to the shower in preference to the radiators if the heating is on and someone opens the hot shower tap while the heating is on until the shower is closed.

Get the support of a Gas Safe engineer

We advise you to call a certified heating professional to look at the diverter valve rather than try to fix it yourself. Any work done on a gas appliance is risky and might harm the boiler if not done appropriately. A boiler engineer can test whether a broken diverter valve is to blame for the issues or if there is another problem at the root. The valve must be cleaned with a commercial chemical cleaner before reinstalling because it has likely grown stuck over time. We advise calling an engineer on the Gas Safe Register to check your diverter valve if you think it might be broken.

It is prohibited to perform maintenance on your boiler, including simple tests that only require removing the boiler cover and checking for the diverter valve. If the valve needs to be changed while your boiler is still covered by its warranty, the manufacturer will cover the cost if you hire a repair provider with that approval. Your boiler will no longer be covered by warranty, so you’ll have to pay for a new valve and the labour to install it if it does need to be replaced. We hope this blog about conducting a Vaillant pressure relief valve replacement was informative.
