Methods of dismantling heating radiators depend first of all on what fasteners are used, and how they are located relative to the radiator.
Typically, cast iron radiators of Soviet models were fixed by a bundle of a union fitting and a lock nut. Modern radiators are fastened with the help of American. Amerikka is a collapsible fitting with a coupling nut.
Connections to the battery can be located in different ways. Connection can be unilateral or bilateral. Why it is so important to find out before unscrewing the radiator? If the installation is made on the bellows, then some of the through plugs on the radiator will be left-hand threaded.
Sometimes in apartment buildings built at the end of the last century there are convectors, connected with supply pipes by a welded seam.

Experts recommend that such preventive maintenance cast iron radiators once every 3-4 years, then it will extend their life for decades. This applies to how to wash the old cast iron radiators, as well as their new counterparts.
Preparing for the job
If there is no desire to run into instances and pay a lot of money for services, you need to know how to clean the cast iron radiators yourself. In principle, there is nothing complicated about this process, if you give it a little time and effort.
As in any other case, it will be necessary to carry out preparatory work. They consist of the following:
- If the flushing is carried out in an apartment, it is necessary to prepare the bathroom. To do this, it is better to put a grid on its bottom, and close the walls with a rag. If there is no tray, then you can apply the same rags, only a thicker layer. This will protect the container from damage and protect the enamel coating. You also need to cover the drain with a fine mesh to prevent debris from getting into the water pipes.
- It is necessary to drain all the water from the heating system, having previously disconnected from the main communication.
- Use an adjustable wrench to remove the threaded clamps from each battery.
- At the point of removal in the pipes need to put plugs.
When disconnecting the radiator from the heating system pipe you should put a container in advance, because water can remain in it as well as in the heater itself.
The next task is how to wash the cast iron battery inside under running water in the bathtub. For this there are both special means, and “folk”.
Disconnecting the first battery section
Get a wrench to disassemble the radiators. If you can not find such a key on sale, you can try to make it yourself. This will require a piece of fittings with a diameter of 20 mm and a length of at least 60 cm. To unscrew the nipple, we need to flatten one of the ends of the fitting to such a state that it is wider than 26 mm, but narrower than 32 mm. To do this use the torch that you have been using to heat the plugs. Heat a section of fittings about 4 cm long at either end. After heating it up with a hammer and shape the tip into a flat shape. If necessary, repeat the heating procedure and hammer the section of fittings again.
The wrench can also be made from a 20 mm piece of pipe. To do this, shape one end of the pipe into a flat shape according to the given dimensions. If you use the factory wrench to disassemble the radiators you do not need any additional equipment. If you have a home-made wrench from fittings or pipe, it is best to use a pipe wrench. It has enough leverage to pull the nipple out of place. Insert the wrench into the radiator just deep enough for the wrench and nipple bit to engage.
Next start unscrewing the nipple in the direction in which you unscrewed the plug.
You can start disassembling the radiator from either the blind plugs side or the through plugs side. Remember that they have left and right threads respectively. If you unscrew the nipple from the blind plug side, then you also twist the nipple clockwise, like a plug. Otherwise you will break the tendrils of the nipple, and then you can disassemble the battery only with a hacksaw for metal.
Make one or one and a half turns. Next, in the same way, make one or one and a half turns at the bottom of the battery. Unscrew each nipple in turn until you have completely removed the section.
Do not immediately try to unscrew the nipple completely. The section as well as the nipple are made of cast iron and are very brittle. You have to unscrew them gradually so they don’t burst. If the fastener does not yield, heat the joint with a torch. It will help, just like with the plug.
It is not necessary to unscrew each section in turn in order to disconnect more than one section. You can go straight to the desired section. To do this, use a radiator wrench to measure the distance to the desired nipple. Use chalk or a marker to make a mark on the key. This will ensure that you don’t miss the right depth when inserting the wrench. Next, begin unscrewing the nipple just as if you were unscrewing a single section. It is important to have a key length of at least 50-60 cm to easily get to the desired section of the radiator and remove it.
How to disassemble an old cast iron battery

How to remove the air lock from an old cast iron battery
Many people wonder how to remove air from the old batteries when there is no Meyevsky valve, which by default equip all new radiators, including cast-iron. But what to do if your old radiator is clogged and there are no wall-mounted taps? As an option it can be installed even on an old-style cast-iron radiator. It is enough to replace the plug on a pipe fitting in which to screw in this notorious Maevsky cocks.
This is what a corks and plugs for cast iron radiators look like in a plumber’s store. In the figure below on the right side there is a blind stopper and on the right side there are connectors, which should be put instead of the blind stopper.
After that you can screw in a hole in the branch pipe itself Maevsky faucet, which will need to use it to release air from the radiator.
However, in order to replace a blind cap on the stud in the battery will have to overlap and drain them, only after the water in the heating system is not left, you can proceed to the modernization of the battery. But for this you need to contact the HOA, because you can not always turn off the battery valves installed directly on it, especially if we are talking about the old wiring radiator from the construction of the house of the Soviet period. In this case you can just unscrew the top faucet or plug on the working radiator. Screw it out, but not all the way out until you hear a hissing sound of air coming out of the battery. Wait a while until instead of air comes out the water from the radiator which means that now the radiator is ready to work and is completely airless. We tighten the plug and forget about this procedure until the next fall.
This is a simple way to bleed air from any radiator without a Mayevsky tap. But this is assuming that the cap can be unscrewed, I mean it is not rusty and unscrews normally. And if while you unscrew the plug tears off the thread or just blows out the plug water pressure and have to pay for repairs of the apartment all who live on the lower floors Dangerous this idea with radiators under pressure Still, there is a way by which you can bleed air with a screwdriver and an electric screwdriver.
Occurrence of air corks in radiators heating can arise for various reasons, some of them can be easily solved by draining the air cork from the battery through a special Mevsky faucet, specially designed to bleed the excess
Regulation of radiators in apartment buildings with manifold distribution very often require adjustment due to the fact that the radiator heating air accumulates in the radiators, which should either be regularly flushed with a Mayevsky faucet, which is not very convenient or

Disassembly of cast iron radiators
Disassembly of cast iron radiators (batteries) for heating begins with the preparation of tools and the selection of the place of work.
Tools for disassembly (repair) of radiators must be prepared in advance. A wrench to disassemble the radiator must fit a 5/4″ nipple. For older battery designs or 1″. for today’s. For easy turning of the wrench, you can prepare a piece of one-inch steel pipe with a length of 500. 700 (1000) mm. To unscrew the fittings or plugs you will need a plumber’s wrench or 3. And do not forget to stock up on a piece of chalk, which will also play a role in this case.

Tips for cast iron radiator repair
Causes that can give us a hint about the radiator inspection are leaks. Can be a leak between sections or a fistula on a section. In the first case it will be necessary to replace the gasket. And in the second. to replace the section itself, since it is not possible to repair the cast iron section at home. The use of adhesives, cold welding, etc.д. this is bullshit. Take my word for it. if a section leaks, it goes in the trash! If you find 50% of the spoiled sections in a radiator, you should not try to assemble such radiator with your own hands, and it is too expensive to do it with the help of others. Have pity on yourself and buy a new radiator.
How to remove the radiator, written here. Removed, put the cast iron radiator on a large rag face up. Take a gas wrench no smaller and try to unscrew the plugs on the side closest to the unusable section. Remember that the radiator sections have different threads on different sides. You can use a hammer to tap on the end of the plugs. Use a wrench to try and unscrew one side, if it doesn’t unscrew, try the other side. If you unscrewed it, fine, if you didn’t unscrew it, no problem. I did the following: put on safety glasses, put the radiator upright, took a chisel and chopped the plug for unscrewing. it was not unscrewed, then I drove the chisel between the plug and the section, just breaking the plug. It will unscrew later anyway. Now move on to the disassembly of the section.
We need a radiator wrench. The key is not difficult to make yourself, the scheme is shown in the picture, or buy. We put the radiator with right thread on the right, left thread on the left. We put the radiator wrench from above with the plate on the joint of the sections, up to the damaged section. We put a mark on the key at the end of the radiator. We put a spanner with a slight twisting motion in the lower hole until the mark is in line and unscrew the nipple in the desired direction. The lower one, because it is easier to unscrew. Even in the summer if there is no water in the heating system, there is moisture in the radiator and does not let the threads dry up. Unscrew the nipple preferably by three turns and screw it back by two. With this action we can wiggle the upper connection, then it will be definitely easier to unscrew. We unscrew the nipples on the other side of the damaged section. But maybe to unscrew some nipple is impossible for some reasons, then it is necessary to saw the nipple with a metal saw and cut the rests out of the section.
Before grouping, clean the filler surfaces, removing any leftover gaskets. Next, take the new nipple and put a paronite gasket on it in the center. Push lightly into the threads of the section, just to hold. The second one is exactly the same. Place the section against the main heat sink until it is fully aligned. Insert a radiator wrench into any nipple and tighten. Feel that the nipple is engaged, it means that it is enough, it is time to twist another nipple. So we twist one by one without skewing. Tighten it with all your might, don’t be afraid to break the thread, even if you want you won’t break it.
