Specialists in Electric Hot Water Cylinders
The combination valve is one of the most important components attached to your unvented cylinder. In fact, it’s crucial for safe operation. Like all components, it will wear over time and will eventually need to be replaced. If you don’t have regular maintenance, you’ll need to replace it much earlier than otherwise. But what are some of the signs to watch for that might indicate a need to replace your combination valve?
Your combination valve includes a pressure-reducing valve. Its job is to reduce the pressure coming from the mains so that it is safe for the cylinder. However, it will eventually fail and if it fails in the closed position, you won’t have any hot water. If you open the hot tap but no water comes out, then you need to check your combination valve (among other things).
Periodically inspect your unvented cylinder. Look for signs of water on the exterior of the cylinder, around the base of the cylinder, and coming from around the combination valve. If you see any signs of water, call a G3-qualified engineer immediately. Do not try to repair any leaks yourself.
Your combination valve includes a pressure-reducing valve. This valve’s job is to reduce the pressure of incoming water so that it doesn’t damage your cylinder. However, if the pressure-reducing valve fails and water flows in at too high a rate, you may hear strange sounds from the cylinder as the increased pressure puts strain on it. If your cylinder begins making unusual sounds, it’s important to have it inspected as soon as possible.
Note that you may also experience strange sounds due to sediment build-up. This occurs when air and water get trapped between layers of sediment. As heat increases, those elements can burst free, creating popping and pinging noises. Note that you should never attempt to stop these sounds on your own.
Your combination valve will include an integral filter. Its job is to prevent large particulates from flowing into the system, where they could cause damage. However, just like your furnace filter, the filter in your unvented cylinder will eventually clog up. When this happens, you’ll notice that the flow of hot water is reduced. Of course, many other issues can also cause similar problems, so it’s always important to have your cylinder inspected by an experienced engineer.
