You can remove drain valves on radiators by using pliers. The flow of heated liquid can be offered to a room through steam and hot water radiators. The radiators work through a single pipe flowing into a valve that links to the radiator. The valve, connecting on both steam and hot water models, is used for controlling the flow of liquid in and out of the radiator. The valve makes the liquid to be forced into the radiator when it is on, and bypasses the radiator when it is off. It's simple to replace a valve on the radiator.
More Instructions
1), Switch the compression fittings or unions off. The connection, called a union or compression joint, is a nut on the pipe. Loose it then you can disconnect the two sections with no need to twist the pipe. Before you remove any of the pipes, you have to separate the union. The connection is linked to the radiator or to the valve coming form inlet pipe.
2), Separate the other connections to the valve. There are three pipes joined together in most valves. Two will be linked with unions or compression fittings, which you need to remove in Step one. Screw other pipes directly into the valve. Use pipe wrench to grip the pipe to make it stable when you are spinning the valve. Rotate the valve connection, which is like a hexagonal nut, conterclockwise by using pipe wrench.
3), Apply thread sealant to the threads of each pipe and fitting involved.
4), Attach the replacement valve in the opposite direction.
Tips
Apply some spray lubricant to the connections with rust and allow it to soak in to aid with the removal of the valve.
