Dripping faucet - what to do ">Tool list - dripping tap:
- Water pump pliers (alternatively set of jaws or socket wrenches)
- Screwdriver Phillips
- Screwdriver longitudinal slot
- Hexagon socket size three and four (Allen key)
Material list - repair fitting:
- Original repair kit cartridge and seals (permanent damage repair)
- Universal sealing and O-rings from the accessories (emergency repair)
- seal fat
- toothbrush
- Rough sponge
- Vinegar or vinegar essence
Important:
Before you start repairing the dripping tap, be sure to shut off the water. To do this, turn the corner valves under the sink clockwise by hand. Then remove the pressure from the line by opening the mixing lever.
When the tap drips - causes:
Any error can be resolved if the cause is known. Without mechanical effects of force, only two common sources of error can be considered for leaks in single-lever mixers. Usually, a dripping tap is created because deposits from the water pipe contaminate the cartridge. Lime adheres to the sealing surfaces and prevents sealing. - The
Mixer drips from the drain.
The second reason for the dripping single lever mixer, preferred in models with movable water spout, are defective gaskets. O-rings harden over time and can no longer seal. In mobile water outlets, usually the faucet in the kitchen, wear the sealing rings, in addition to curing, also mechanically. Every movement of the water outlet minimizes abrasion of the rings.
In this case, the water usually drips out of the designated opening. Instead, it runs out of the dividing planes of the moving elements.
Tip:
Before disassembly, close the spout so that any falling screws and small parts do not end up in the drain.

2. Assembly instructions
Step 1 - Disassemble the mixer lever
Single-lever mixers are visually quite different from each other. Apart from the design, reduced to the basic structure, but they are almost the same. To disassemble are all moving elements. (Mixing lever and the movable water drain). The mechanical framework remains firmly attached to the sink or wall.
The mixing lever is usually held in fittings with rigid water outlet only by a hidden screw. It is located either under the red blue screen (symbol for hot - cold) on the front or exactly opposite. In the usual kitchen mixers with movable neck hiding mostly two screws under a vertically plugged lid.
Tip:
Move the lid slightly to open without tilting it. It is almost always made of plastic and is only attached - not screwed. Unfortunately, plastic hardens with age and becomes brittle. Tilt too hard, breaks off something quickly.
Tool used:
- Flat-head screwdriver or test pin
- Phillips screwdriver or hexagon socket (manufacturer-dependent)
As soon as the mixing arm has been disassembled, you are already looking at the "heart" of your valve. Each single-lever mixer mixes the water inside the cartridge. It consists externally mostly of plastic. To ensure the tightness inside the cartridge either plastic or ceramic components.
Lack of tightness inside the cartridge that can not be opened is the main cause of dripping single lever mixer. Unfortunately, the component can not be repaired. It is completely replaced. The spare part number or the type designation of the faucet can be found on the already mentioned label of the supply line.
Step 2 - Change cartridge
The cartridge is held by a clamping nut. In a well-equipped toolbox, there is a matching socket wrench. If necessary, the dismantling works as well with a fork wrench or water pump pliers. Much effort is not necessary to loosen the screw. By default, the screws are tightened with about 12 Newton meters of torque. (Good hand-tight).
As soon as the clamping nut is loosened, the cartridge and all moving parts can be easily removed.
Important:
Please memorize the order of construction exactly. Place the parts in a sequential order on a secure tray.
Tip for emergency repair:
As an emergency repair, until the original spare parts are delivered, it is often sufficient to put the old cartridge in vinegar overnight.
Please do not clean sealing rings in vinegar, otherwise they will harden unnecessarily. It is enough to clean them with a little detergent and a nail brush. Then "grease" thick with sealing grease.
In the short term, the tap stops dripping without actually repairing it sustainably.
Used tools:
