What Should The Pressure Gauge Read?

Each boiler has a pressure gauge that measures the pressure that is inside the boiler. The general reading of pressure should be between 1.0 and 1.5 on the pressure gauge. This is a steady point for the pressure level. However, if at any point the pressure drops below 1.0 you may find you need to pressurise it. Doing this will put it back to a safe and steady level of pressure.


How Do I Get My Boiler to The Right Pressure?

If your boiler’s pressure is too high, then you can lessen it by bleeding a radiator. The result of this will lessen the amount of pressure in your central heating system and therefore your boiler. However, if the pressure of your boiler is too low, you may find that opening both valves on your boiler will help. Doing this will let a flow of mains water back into your boiler. Keep an eye on it until it reaches the appropriate pressure level (1.0-1.5) and then close each valve, one at a time.


Why Does My Boiler Lose Pressure?

Your boiler may be losing pressure as a result of wear and tear. The older a boiler gets, the more they tend to struggle. A solution to this would be to call out a plumber and potentially have a new boiler fitted. However, the pressure loss may also be a result of an underlying problem in the boiler or central heating. To fully have this diagnosed you may find you benefit from calling a plumber.


How Do I Bleed My Radiator?

To a bleed radiator, you first need to turn off the central heating and then find the radiator key. If you can’t find the key, then a flat-head screwdriver will work just the same. With the key, open the valve to release the air trapped in the radiator. When doing this, a hissing noise will begin to indicate the air is leaving. During the process ensure that you have a cloth to catch any water that may leak out. Once finished, close the valve and check on the radiator a few hours later to check it’s heating correctly.


Why isn’t My Water Hot?

There could be many reasons as to why your water isn’t hot. The main reason being that perhaps your boiler has broken down. If it’s not that it has broken down, then it may be something to do with a valve in the boiler called a diverter valve. It may have got stuck, worn out or become faulty. There may even be a chance that you have blocked drains. If you have blocked drains in Essex, get in touch with one of our plumbers today to resolve the issue.
