10 Methods How to Drain a Radiator System
Use the Drain Valve:
Most radiators are equipped with a drain valve located at the bottom or side. Start by turning off the heating system and allowing the radiators to cool. Place a container beneath the drain valve, and using a wrench or a radiator key, slowly open the valve in a counterclockwise direction.
Allow the water to flow out into the container until it stops. Make sure to re-tighten the drain valve before turning the system back on. Additionally, if the drain valve is corroded or stuck, use a lubricant such as WD-40 to help free it up.
Utilize a Radiator Key:
Some radiators may have a bleeding valve instead of a drain valve. If this is the case, you can use a radiator key to release air and water from the system. Insert the key into the valve and turn it counterclockwise. Slowly open the valve until water begins to flow. Catch the water in a container and continue until the flow stops. Once the flow has stopped, close the valve and reinstall the radiator key.
Now that you have drained your radiator system, it is important to refill it. Use a funnel to fill the radiator with fresh coolant or antifreeze, and check the level of your system using the overflow tank.
If necessary, keep topping up the radiator until it is full. Finally, turn your system back on and check for any leaks that may have occurred during the draining process. If all is well, your radiator should be ready to use.
Gravity Drainage:
Gravity drainage is another effective method to drain a radiator system. Start by turning off the heating system and allowing the radiators to cool. Locate the highest radiator in your system and attach a hose to the drain valve. Place the other end of the hose outside or in a suitable drainage area.
Open the drain valve and let gravity assist in draining the water from the system. As the water level decreases, open each valve in the system to assist in draining it. Once all of the radiators have been emptied and drained, switch off the drain valve and remove the hose. The radiator system will now be completely drained.
Power Flush:
If your radiator system is severely contaminated with rust and sediment, a power flush can effectively remove the buildup. This method requires the use of a specialized power flushing machine that circulates cleaning chemicals and water through the system. Consult a professional plumber or heating engineer to perform this procedure safely and effectively.
Once the power flush is complete, it’s important to top up the system with a good quality inhibitor. Inhibitors are chemical substances that protect against corrosion and scale build-ups, and help to keep the radiators running efficiently.
Radiator Key Bleeding:
Bleeding your radiators using a radiator key is a common method to remove trapped air from the system. Air pockets can hinder the efficiency of your heating system. Start by turning off the heating system and allowing the radiators to cool. Insert the radiator key into the bleeding valve, located at the top of the radiator, and turn it counterclockwise. Release the trapped air until only water flows out.
Collect the water in a bucket or container to avoid dripping onto carpets and floors. Once the water runs clear, close the valve by turning it clockwise. Repeat this process for each radiator in your home.
After the last one is complete, turn the heating system back on and check that the radiators have heated up evenly. If you hear any banging or gurgling noises, the system may need to be bled again. Make sure to
Hose Disconnect Method:
If your radiator system has flexible hoses, you can use the hose disconnect method to drain the system. Begin by turning off the heating system and allowing the radiators to cool. Locate the flexible hoses connected to the radiators and carefully disconnect them.
Direct the hoses into a suitable container or drainage area and allow the water to flow out until it stops. Make sure you close off any air vents that may be connected to the radiator system as well. Once the water has been completely drained, double-check that all of the valves are closed before turning the heating system back on.
