How to fix the tapIn order to fix the faucet it is not necessary to call the plumber or contact the housing office, you can do it yourself. Repairing a crane is often much easier than changing it to another crane, and not every breakdown requires the purchase of a new product. But if the purchase is still to be done, then we recommend it to be made in Santop plumbing online store, where the widest range of sanitary devices and equipment for heating systems is presented.

In order to repair the crane with your own hands, you need to understand its design. The illustration shows the head, which is screwed into most of the taps installed in kitchens and bathrooms. The head is a design of the type of screw and nut, where the body plays the role of a nut, and a spindle is installed instead of a screw. When closing the valve, the spindle presses the valve along with the gasket to the seat of the mixer body or valve and closes the water.

Before repairing the tap, turn off the water using a valve at the inlet (it is usually installed in the toilet).Before you unscrew the head, you need to slightly open the valve, the spindle slightly moved away from the saddle. It is best to unscrew the head with a wrench or spanner. After repair, the head is taken in the left hand and the old seal is removed from the groove. Then a string of flax or a burlap thread is wound around this place. When the seal becomes cone-shaped, the seal is moistened with water to secure the fibers. After that, the head is put in place, and before opening the valve, the handwheel is wrapped so that the gasket sits in place and reliably closes the saddle.

When repairing the crane head, four parts may be needed: a valve, a gasket, a spindle with a screw for fastening the flywheel, and an stuffing box.


Sometimes when repairing a crane it is found that the walls of the valve socket have crumbled and if more than half of the circumference is damaged, then such a valve can no longer be repaired. The gasket in such a nest does not fit and therefore the valve flows. New valve can be found in the store or turn it on a lathe from brass billet. You can take the valve from the old head, which can be searched on the market or in stocks of friends.

Sometimes when unscrewing the head, the valve remains on the mixer and to get it you can use a wire hook or tweezers. When riveting the hole, it is not necessary to drive the valve stem into it, it is specially fixed in the mixer hole, so that the gasket wears evenly. In order to prevent the valve from falling out of the spindle, you can wind a little seal on the valve stem and forcefully install it in the to fix current tap


If the valve flows for several days even with the spindle fully screwed in, the wear of the gasket is the cause — it could harden, wear out, or it could cut the sharp edges of the saddle.

It is necessary to unscrew the head and unscrew the screw fastening gaskets. It is better to use gaskets, with a diameter per millimeter larger than the valve seat, it is necessary that the gasket be firmly held in the socket. The protruding edges of the gasket can be cut with scissors in a circle at 45 degrees.

Sometimes you can not change the gasket, and repair it. For example, when the pipes “roar”, the gasket is to blame, and it is necessary to remove the crane head, cut the protruding edge of the gasket.

When replacing the gasket, if the store was not suitable, you can make it yourself from a piece of hard rubber of hardness. Microporous rubber is too soft and plastic too hard. A suitable piece of rubber is placed on a wooden plate and cut it to the desired diameter using a sharp knife, not one smooth movement, but as if cutting bread into slices - the result is a polygon with a large number of sides.


If a water jet flows from the tap and you cannot close it, the spindle is to blame. In this case, overlap the water and turn the head. In this case, you can see that a few extreme threads of the external thread of the spindle have been erased from the side of the flywheel. On the outer part of the spindle, a suitable length of thread usually remains and can be used if you install a gasket not less than six mm thick. Since such a gasket is quite difficult to find, you can pick up washers with a thickness of 1.5-3 mm. The inner and outer diameter of these washers should correspond to the diameter of the spindle shank and the valve seat. In extreme cases, you can replace the spindle.To do this, remove the handwheel cover, turn out the screw, remove the handwheel itself and turn out the stuffing box sleeve. Then carefully wrap the new spindle, making sure that the spindle thread coincides with the thread of the head body. Sometimes it's easier to replace the entire head.

In some cases it is easy to replace the spindle does not give naughty screw. They fix it this way: they insert the head into the screw slot and hit it several times with a hammer. If the screw does not give in and in this case, then the screw head simply break off and change the spindle. If the screw breaks on a suitable spindle, the fracture is grinded to the plane with a file and, tilting the spindle in the center, drill a hole in it and cut a new thread in it. In order for the screw not to rust, it is necessary to lubricate it and screw it back.

Body and sleeve

The body of the crane also has a thread that has a tendency to abrasion. Sometimes when opening a tap, water begins to drip from the stuffing box. You can try to tighten it with a key, but without much effort, because the spindle will not rotate. If this does not help, you can replace the packing groove gland. To do this, close the valve, remove the handwheel cover, unscrew the fastening screw and remove the handwheel.The key to hold the body for chamfers, and the other key to turn out the sleeve. The hull must be fixed. With an awl or thin wire we remove the stuffing box between the sleeve and the gasket. It is better not to touch the old gasket, but simply add a new one. It is better to always lay a new gasket in the direction of tightening the sleeve. After laying the threads they are tamped down with a screwdriver, making sure that the groove of the case is not overflowing. After winding up a part of the packing, wrap the sleeve before pressing the packing, turn the sleeve and add another packing. For greater moisture resistance, you can soak the packing with any oil. Then assemble the crane in the reverse order.
