How does Gunson Eezibleed work?

By using the air pressure from the spare wheel, the Gunson Eezibleed will effortlessly bleed any hydraulic system. The new brake fluid is pressurised by attaching the Eezibleed tube to the spare tyre. Then release the brake bleed valves in turn and let the air bubbles and old fluid flush out through the drain tube.

Should both radiator valves be open?

You should open both of the valves on all of your system’s radiator when you are starting the radiator balancing process. You will most likely need to use pliers to open the lockshield valve. Once this is done your radiator system should be fully balanced and your radiators should heat up evenly and efficiently.

What are the 2 valves on a radiator?

One valve accounts for the amount of hot water that enters the radiator. The other valve, referred to as the lockshield valve, balances the system by regulating how much heat the radiator gives off.

Where is the bleed valve on an old radiator?

Most radiators are bled using a radiator key but if you’re not sure, find a bleed valve. They’re located on the left or right side of the radiator at the top. A bleed valve on an older radiator looks like a hole with a square bit in the middle.

How do you Bleed a hot water radiator?

How to Bleed a Hot Water Radiator Step 1: Locate the small valve on the side of the radiator, usually toward the top. Step 2: Using your radiator key (or a flat-head screwdriver), turn the valve counterclockwise. Step 3: Repeat this process with all of the radiators within your home, so none of them contain any trapped air moving forward.

What does bleeder valve mean?

A Bleed Valve is a screw-type valve that is used to release any trapped vapor or liquid from a system. These valves are small in size and are usually installed on blow out preventers, pipelines, storage tanks and pumps.
