Even the most reliable cranes over time begin to skip water - flow or drip. To fix the faucet, it is not always necessary to call plumbing. Most of the breakdowns can be eliminated independently. But, before repairing the dripping crane, it is necessary to figure it out in its design and the order of work.
CONSTRUCTION Crane do it yourself - the task of medium difficulty

Let's start with definitions. There are in the bathroom and do not kitchen cranes and mixers. Cranes only feed water, mixers also allow you to adjust its temperature, mixing two streams - cold and hot water. In this article we will talk about the cranes and how to repair them. The repair of the mixers is very similar, but has its own characteristics. By the way, you can read about the repair of single-art mixers here.
Cranes for the bathroom or kitchen have several types:
- valve;
- Single-art (still called cartridge or flag).
Cranes - flag and valve
They have a different device, so that the repair, even with the same damage, is significantly different. Therefore, each of the species will be considered separately.
DIY repair of the valve crane
The valve cranes can be called a classic water supply. And, at least, they gradually push out new designs, they are still plentiful. Their internal structure has not changed over decades. Only design was changed - it became more diverse and exquisite. Today you can find both the most ordinary models and very exotic.
The structure of valve cranes
Water disposal cranes of this type are still used, as they are simple and reliable, serve without years, but decades. If the whole "filling" of proper quality, all that may fail during this time are strips. Their replacement is the main way to fix the valve crane.
Replacing rubber gasket
If, with a fully closed valve, the faucet in the kitchen or in the bathroom continues to drip, most likely, the reason for the launching of the gasket on the valve (see the photo in the next paragraph). She stopped tightly clinging to the saddle, because of which the water continues to flow and sometimes the crane does not just drip, but even flows. Repair the crane in this case - replace the gasket. This will require a spanner, and better - adjustable key and set of gaskets.
Before repairing the dripping crane, turn off the water supply (you can completely, you can only in this thread, if possible). Next, it is necessary to make sure that the water is blocked. Water does not flow - begin repair. It is necessary to wrench or adjustable key. They will need to unscrew the head housing (the top of the case).
It is better to work by an adjustable key. In order to do not damage the surface at the operation, turn it with a soft cloth, and then superimpose the key. By reloading the head, take out the valve. Now you can replace the gasket or put a new valve. Old ways to be sharp - you can with a screwdriver with a flat spatula, can be shill, etc.
When choosing a gasket, note that its edges must be mowed at about 45 °, otherwise the water pipe will be noise. If there is no such arsenal, you can focus the edge with something sharp - with a knife or scissors.
Replacing the gasket in the crane in pictures
If there is no suitable gasket, it can be cut out of a tight rubber sheet (porous does not fit). The thickness of the rubber sheet or gasket is 3.5 mm, the inner diameter is a little less than the rod diameter, the outer should not perform. Do not forget about the edges beveled under 45 °.
By installing the gasket, put the valve to the place, spin the head. New models of presence winding on the thread do not require. Moreover, the winding is contraindicated - it can cause the appearance of a crack in the housing. If the old crane of the Times of the USSR is repaired, the passage is placed on the thread, lubricate the packaging paste, then spin. After that, it can be gradually turned on the water.
Sometimes the opposite story happens with this gasket on the valve - water does not flow or barely. In this case, the gasket flew from the rod and blocked the flow of water. You can first try to open / close the crane a couple of times, and if it does not help - you need to repeat the operation described above, that is, repair the crane replacing the gasket. Just do not forget to remove the old one sticking to the saddle.
Water wakes out of stock
If water drips from under the valve, the glands were most likely worn. Channel a crane with a flow from the stock in two ways. First you can try to stronger the head housing more stronger. Do it again by the confusion key. Use pliers is undesirable because after them traces remain. Tighten the head as much as possible (only do not overdo it).
The structure of the valve crane
If the thread is tightened as much as possible, and the water continues to appear, it is necessary to replace the gaskets on the gland. To do this, first twist the tap to the limit, then again remove the crane head, something sharp approach and remove both rubber rings, replacing them with new ones.
Water does not overlap
If the gasket is changed, and the water does not overlap, when rotating the crane, the thread occurs, it is necessary to change the rod - the carving on it was carried out. Options There are two - replace the rod itself or completely the entire valve head.
In the saddle can be a promo
If the thread is not broken, the gasket is new, but the crane flows, inspect the saddle. It may appear promin. It is formed gradually - it is washed with water supplied with high pressure. If the gasket in some place is pressed, the sink is formed in this place. Sometimes water is fully tapping the entire circumference, forming sharp edges, which quickly damage the gasket. Wine and sharp edge should be removed. You take a conventional screwdriver and spending it on the edge to dulp the sharp edge. The same operation can be done with the help of a natphille or a piece of sandpaper with small grain. The main thing is to achieve even (as far as possible) and unsoldurated edges.
How to fix the crane with the cartridge
Most often in the bathroom or in the kitchen there are cranes with one lever. From the name more flag or one-art. For the opening / closing of water in it, the special device - the cartridge corresponds to it, because they are also called cartridges.
Cartridge crane
Inside the cartridge there are two plates with holes. The bottom is fixed rigidly, and the upper move. It is attached to the rod, and in turn - to the handle. Turning the handle, we move the rod, and it shifts the movable plate, which opens / closes the water and changes its pressure.
If problems with such a crane, you can repair it only by replacing the cartridge. The main problem in them - they begin to flow - the water is worse or dripped from under the handle. To repair the current or dripping cartridge crane, you must replace the cartridge. The only way.
Replacing the cartridge
First of all, it is necessary to overlap water, then - remove the handle. To do this, take a color plug first - it closes the screw. By revealing the screw, the handle pull up, separating from the rod. After the knob is removed, unscrew the clamping ring - it holds the cartridge. Now it remains only to remove it.
Then, together with the cartridge, you need to go to the store or to the market, to buy exactly the same. The new must match the sizes, the holes in its lower part must have the same form and location. In general, you need to find an exact copy.
How to disassemble a tap with cartridge
The assembly occurs in the reverse order:
- We put the cartridge (strictly vertically, slightly sroll around your axis, so that the protrusions in the housing are in the excavation on the cartridge),
- tighten the clamping nut;
- Install the handle;
- Screw the locking screw;
- Insert the plug.
Initial checks can be carried out after installed the clamping ring. You can open water and check if the crane does not flow now.
If the flow of water has become too weak
Most modern cranes are equipped with a grid, which delays solid particles that may be contained in the plumbing. If gradually the water stream has become not so elastic, and the pressure on other cranes has not changed, the reason is to clog the grid itself. In this case, you can repair the crane in a couple of minutes.
It is necessary to clean the grid
Remove the nut with the grid, which is at the end of the spout. Rinse it, clean the slaughtered holes (by a needle or an old toothbrush). Remove the grid set to the place.
