Knowing how to change a radiator valve can be extremely useful for homeowners looking to maintain their heating system. A faulty valve can lead to leaks, poor heat control, or a radiator that doesn’t warm up properly. While some people feel confident attempting to DIY this task, others prefer to work with professional plumbers near me. Today we’re going to share with you a complete guide to changing a radiator valve. Contact us today for more information about the services we offer if you feel you need support with this task.
What Is a Radiator Valve?
Before learning the steps on how to change a radiator valve, it’s important to know what a radiator valve actually does. A radiator valve regulates the flow of hot water entering your radiator from the central heating system. By adjusting the valve, you can control the heat output. Modern thermostatic radiator valves (TRVs) can even detect room temperature and adjust themselves automatically. The radiator valve is a small component of your heating system, which sits at the bottom of the radiator and connects it to your pipework.
There are two main types of radiator valves that a plumbing service in Warrington can support you with. Manual Radiator Valves operate in a similar way to a tap. You simply turn the valve to increase or decrease the flow of hot water. Thermostatic Radiator Valves (TRVs) are a modern solution which offer more control. They automatically adjust the flow of water based on your room’s temperature, helping to reduce energy usage and heating bills. Radiator valves sometimes need replacing due to leaks, age, or corrosion. Some homeowners opt to have these changed as well, just to make their heating system more efficient. Whatever the reason for you needing to change a radiator valve, the process that Warrington plumbers will follow is usually pretty similar.
Tools and Materials You Will Need to Change a Radiator Valve
While a plumbing company in Warrington will be able to supply all of the tools and materials for this job, if you are taking the DIY route, you are going to need to make sure you have the right supplies before attempting to complete this task.
Before you begin, collect the following materials and tools together:
- A new radiator valve
- Adjustable spanner
- Radiator bleed key
- PTFE tape
- Towels or rags
- A bowl for catching water
- Pipe grips
How to Change a Radiator Valve
Now that you have all the tools and materials you need for the job, it’s time to follow our step-by-step guide on how to change a radiator valve. While this guide is suitable for many radiators, if you don’t feel confident at this stage, we recommend contacting a professional plumbing company in Warrington for support. It’s much safer to outsource this job than cause damage to your home or heating system.
Turn Off Your Heating and Isolate the Radiator
Ensure your heating is completely off before you start work. Give the system time to cool down, as working on a hot radiator can be dangerous and may result in burns. You will then need to close both valves on your radiator. Turn the control valve clockwise until it stops. On the lockshield valve, which is usually found on the opposite side, remove the plastic cap and turn it clockwise using pliers until it is fully closed.
Drain the Radiator
Place a bowl beneath the valve and loosen the nut that connects it to the radiator. Once this is done, water will begin to drain out. Open the bleed valve using a radiator key to help speed up the process, and then allow the radiator to empty completely before proceeding to the next step.
Remove the Old Valve
Once drained, fully loosen the nuts on both sides of the valve and carefully remove the old valve from the pipework. You can then wrap PTFE tape around the threads of the pipe to ensure you have a watertight seal when you attach the new valve.
Fit the New Radiator Valve and Refill the Radiator
Put the new valve in place and tighten the nuts securely, holding the pipe steady to avoid damage. Take your time to ensure the valve is aligned correctly to avoid future leaks. Close the bleed valve and reopen both radiator valves. Water should start flowing back into the radiator, and then you’ll just want to test that the system works properly and everything is back to normal after your work is complete.
Changing a radiator valve is manageable for those who are confident with DIY tasks, but there are times when professional help is the safer choice.
