CALL NOWEven if it does come out that the issue results from an outdated or damaged pressure relief valve, replacing the valve on a boiler is not as simple as plunging a clogged toilet.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.

CALL NOWA 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.
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.
