you need
  • - a screwdriver or pliers;
  • - pipe wrench;
  • - the capacity to drain water.
easy descent to the air and radiator heating systems should be installed bleed screw or automatic valves.In addition, the battery is supplied to the pipes must be valves allowing, if necessary, block the water.
If the radiator has a bleed screw, lowering procedure air and is very simple.Take container, which can be put under the tap - for example, a bucket, a bucket, a large bowl.You can put a rag.Then, with your hands or pliers (some cranes with a screwdriver) loosen the head of the crane.You will hear the whistle of escaping air well: you have to wait to go from the tap water (do not worry, its head will be very weak) and then close the val
ve.In that case, if the radiator thermostat is installed, the air before descending and it should be fully open.
harder to pull air of the radiator in the case of a special crane on it is not.In this case, you'll need a pipe wrench to unscrew the top cap.Very often the cap is screwed on tow with paint, so in order to "rip" it away, you may need quite a lot of effort.Once stronulas cap, loosen it until you hear the sound of escaping air well.Release all air , this may take a little shake the battery, then re-tighten the cap.If necessary podmotayte to thread tape FUM.
the absence on the radiator water shutoff valves work very carefully.It is important not to overdo it and do not unscrew the cap completely, as to put it back in the absence of cranes and boiling water gushing from the radiator, will be almost impossible.Available on the radiator valves solves many problems associated with etching and air, radiator repair, replace them.If the radiator suddenly began to flow, you can always cut off the water and easy to do troubleshooting.With the help of cranes You can also adjust the temperature in the rooms.
