The phrase "gas column" is usually called a flow gas water heater, which is installed for water heating in homes that are not connected to centralized heating. This method of heating has a lot of advantages, an important of which is independence from public services and preventive work, which allows you to always have heat and hot water in the house.
However, the problems of residents of houses connected to the gas pipeline have a lot. One of the most frequent trouble is a breakdown of gas equipment that can entail very serious, and even life-threatening consequences. About what to do if you find leaks in the gas column, read in our current article.
Why happens?
We have compiled a list of the most common reasons, because of which the gas water heater begins to leak. So, if you suspect the presence of a leakage, then maybe the reason will be one of the following:
- Connecting elements of water pipeline were worn. That is, in other words, we need to replace rubber sealing gaskets located between the hose and the pipe.
- The heat exchanger broke through, that is, a kind of "tank", in which the water heats up. The pipe attached to it is permanently exposed to temperature drops, as a result of which they can deform and corrosive.
- Regular prophylactic works were carried out. A gas column is an equipment that needs periodic inspection and maintenance, in order to prevent breakdowns. If you neglect these responsibilities, the flow may appear unexpectedly.
How to eliminate leak?
Reaching the cause of the occurrence of leaks, it is possible to adjust it. Further actions will depend on which part of the gas column is a source of leakage.
Leakage in the radiator
The fact that there is a crack or a sliver in the radiator, signals the presence of green spots on this part. The procedure for eliminating leakage in the radiator will be as follows:- We overlap the water pipes so that water does not flow into the column. Disconnect water supply hoses from the column. We merge water remnants from the radiator. To remove the liquid from the coil, we use a vacuum cleaner or pump.
- Armed with sandpaper, we clean damaged areas. Then we processes these places by the degreasing solution and wipe dry.
- We take a soldering iron with a solder that can be used at temperatures above 180 degrees (the power of the soldering iron should be at least 100 W). Grind a piece of rosin or rub into powder Pill aspirin. We sprinkle the work surface with this composition.
- Heating soldering iron to the desired temperature, we increase the solder to a height of about 0.2 cm.
- We repeat this procedure for each end-to-end damage.

Leakage in threaded connections
Quite often, you can detect the leak in the threaded connections between the parts of the gas column. Pay attention to what pipe was formed to flow: water was usually supplied for heating, and the right - gas. As a rule, water begins to leak out of the pipe if the sealing gasket was worn. Change this spare part is very easy.
- The first thing to do is to block the flow of water.
- Then disassemble the connection in which the problem is detected (we use a regular wrench for this purpose). Remove the exhaust gasket.
- Connecting elements Clean from contamination and degrease.
- If the carving is damaged on the American Nut, it should be replaced.
- Then set a new rubber gasket and collect a connection.
Leakage in tubes
Sometimes the leakage is detected not in the connection of the tubes, but directly in them. Specialists advise when detecting cracks and small spacing in the tubes to use the same way as to eliminate leaks in the radiator, that is, to solder. However, in the absence of proper care, it is not always possible to detect damage in time. If you have tried too late, and the tube managed to make sure that it is not subject to repair, it will have to replace it.Those who have encountered a similar problem say that it is very difficult to find a suitable tube, even in stores specializing in the sale of gas equipment. As a replacement of the tube, you can use a corrugated stainless steel hose or flexible water supply.

Replacing a water node stock seal
Another possible places for the appearance of leaks are a gas-breeding node. If the water began to be frozen from him, most likely, the stock sealing rings took place. This spare part will be easy to replace.

The parts of the water node fasten six screws - we unscrew these fasteners first. Then disconnect the two parts of the housing of the node. From the inside removing the membrane, spring and a plate with a rod, which is a round disk with a metal pin. If you unscrew this pin, you can detect the rubber ring under it - this is the seal. Remove the wear ring, we put a new one in its place and collect the node in the reverse order.
