Among the appliances that cannot be replaced by anything in an apartment or a country house, in the first place, a boiler can be called. And that’s why problems arise when the equipment fails. What to do if the water heater is leaking?
If the water heater is leaking, then you must immediately find the cause of the breakdown and eliminate it. If timely measures are not taken, the consequences can be the most unpredictable. Moreover, to eliminate them, you will need a lot of time.
Let’s not forget that any repair involves considerable costs. We also note that a faulty boiler often causes flooding. The problem is that you can flood not only your own apartment. If you live in a high-rise building, you can also flood your neighbors.
Human security issues are also associated with such a breakdown. The fact is that there is a risk of electric shock.
IMPORTANT! The first step is to find the cause of the boiler leak. We remind you that this should be done when the device is disconnected from the mains and the water supply is shut off. Practice has shown that quite often such a problem arises: water flows out of the upper or lower part of the boiler, which does not allow the equipment to be operated normally.
This article is to help those who encounter such a problem. Here he can read about the reasons why the tank is leaking; about methods that allow you to eliminate them with your own hands. We will also tell you how to prevent such breakdowns of the device.
Causes of a water heater leakage
You have found that the tank is leaking from the top or bottom. What to do? Disconnect the appliance from the mains without delay. Use a flashlight and inspect. You need to determine where the water is flowing.
The boiler can leak for various reasons. How quickly and correctly you determine the cause depends on the ability to carry out repairs on your own.
It is possible that after inspection you will determine: the body is leaking from below. It is possible that the gaskets or the shell of the heating element are worn out. If the leak is on the side or bottom, then look for a hole in the tank.
The main reasons due to which the case becomes leaky:
– Marriage admitted in production. In this case, the leak will start shortly after the appliance is installed.
– Production preventive work has not been carried out. At least once a year, the hull should be inspected for damage and scaling.
– There was no magnesium anode replacement.
– The water used is hard, it contains a lot of impurities.
– There is no grounding of equipment.
IMPORTANT! The reasons do not depend on the brand of the water heater – Ariston, Novatek, Termex. They are common to any brand. How to accurately identify the problem? How to eliminate it with your own hands?
Most often, water leaks due to the fact that the outer shell is deformed. This problem usually manifests itself in the case when the rules for installing the boiler were violated. Do not look for manufacturer’s faults here. Water that drips on the outer shell of a water heater can often be detected almost immediately after the appliance has been installed.
Shortly after you have connected the appliance, you will notice water dripping from the tank. And the shell of the body is inflated or deformed. Why?
You did the installation yourself and did not remember the safety valve, or its connection was incorrect. That is why the container overflows with water, swells, and then starts to leak.
It is necessary to install a valve that will protect the system from overpressure. If the valve is installed incorrectly or broken, then the tank is subject to deformation when the water is drained from the system.
IMPORTANT! You turned off the boiler, turned off the water. Inside, hot water begins to cool, decrease in volume. Buck shrinks. When the water is drained from the entire system, a vacuum occurs inside the tank. When at this time the safety valve is out of order or it does not exist at all, then deformation of the container cannot be avoided.
Then the product will be filled with liquid again. When heated, it expands. As a result, the tank is inflated. If the deformation is severe, then repair is out of the question. You are waiting for the installation of a new device.
The negative impact of corrosion
If you have not made a replacement for the magnesium anode, then do not be surprised that the boiler leaks.
Magnesium attracts the salts contained in the water. Gradually, all sorts of impurities settle on the anode. From this, he begins to collapse. The tank and the heater initially remain undamaged. But when the anode is destroyed a long time ago, this will lead to corrosion of the metal case.
Prevention can give good results. You only need to replace the rod once or twice a year.
The dry heating element has a shell made of steel and enamel. Wear also leads to corrosion. Can a leaking item be recovered? Not! Salvation is only in its replacement.
Other common causes of leakage
– Pipes of poor quality or incorrectly connected
If water drips from pipes or connections, sealing of connections is necessary. Replace gasket or fum tape. Metal-plastic pipes are better suited, since the body suffers after a water hammer.
When the supply channels are not tightly connected, the boiler flows. Check all connections.
– Worn flange (gasket)
The heating element and the magnesium anode are located on the flange. The gasket is needed for tightness. In case of wear, it flows from below. Replace the gasket, tighten the fixing nuts.
– No grounding
The device must be grounded. When the current breaks through the case, it will be subject to electrical corrosion. There is also a danger to life: water from a tap or the surface of the tank breaks through the current.
IMPORTANT! If the problem is not in the parts of the water heater that have worn out, then there is no point in repairing the tank. A broken case means that you need to purchase a new device.
Where else can there be leaks?
– Heating element is leaking
Not every model has a special hole through which water flows when the heater starts to leak. You need to check its presence when you buy a boiler.
– Leaking safety valve
This element of the boiler is a small tap with a hole. You need to replace the part with a new one.
– Storage tank lid is leaking
Possible leakage of the heating element, which was provoked by a large accumulation of scale.
– Storage tank is leaking
Leakage of liquid along the liner means that the storage tank is leaking. This is a consequence of violations of the installation or connection rules.
IMPORTANT! When connecting a water heater, do not use plastic pipes. Otherwise, hydraulic shocks will be transmitted to the tank. And this leads to its destruction.
– Leaks in the upper part, although visual damage is not visible
If it leaks at the top of the water heater and no deformations are visible, and the installation and connection were correct, the magnesium rod was checked and changed, then return the device to the store before the warranty period has expired.
Can a leaking boiler be repaired?
Before you begin troubleshooting, have the following tools ready:
– hoses for water outflow;
– a screwdriver, adjustable, tubular and socket wrenches;
If there is a leak, unplug the appliance from the mains and drain all the water. Empty the tank. And start the inspection to establish the cause of the breakdown.
The reasons for the leak, as we have already found out, are different. Therefore, in some cases, you will find a simple repair. In others, you have to change the boiler. It is better to do it within the warranty period.
If the device is leaky (in particular, the tank), as indicated by water leaks from the joints of the nozzles, then it will not be possible to repair it. Need a replacement.
If you followed all the rules of care and changed the magnesium rod in a timely manner, then leakage from above will require replacing the boiler. Repair is out of the question. The boiler is changed when the magnesium rod has not been replaced for a very long time. As a result, the tank is rotten, unless, of course, the inner surface has enamel.
The alteration of the water supply system is started when the rules for connecting the boiler to it have been violated. Especially when plastic pipes were used and when there is no special safety valve.
If the boiler tank is in good condition, and only the valve itself is leaking, then it needs to be replaced.
In order to get rid of the leakage of the tank cover of the water heater, it is enough just to replace the heater.
IMPORTANT! When the tank itself leaks, there is no way to restore it, since the boiler is a monolithic structure. And her insides are covered with enamel.
If the enamel inside the water heater is damaged, it can no longer be repaired. There is only one solution to the problem – we buy a new boiler.
