Sink faucet device and its typical faults

What kind of mixers are designed to work with a sink or washbasin? What are they made of? What malfunctions are typical for different designs and how are they eliminated? Let's try to answer these questions.

Species classification

To begin with, let's find out by what signs these products can be classified.

Installation

There are two options here:

1. Most modern products are attached to the sink with a nut, which is screwed on the body of the mixer, or a rigid plate, pressed to it with one or two nuts on the studs. The mixer is connected to the plumbing by a pair of flexible hoses in a metal sheath.

Curiously: a couple of decades ago, domestic mixers with rigid liners were distributed. Their main problem was that the installation required careful adjustment of the sizes of the pipes. Fortunately, now these products have practically disappeared from sale.

1. The faucet for the sink of the wall is designed for steel with the appropriate wiring pipes or for very compact kitchens. It allows you to save a few centimeters of space by eliminating the shelf at the sink.

Gander

The gander (or spout) may be in a fixed position or be movable. The first option is suitable for the sink, the second - for the sink: when washing dishes, it will provide an opportunity to put an overall pan or vase in the sink.

However: there is a weak spot in the rolling gander - gaskets that ensure the tightness of the rotary part of the hull. They can crack when there is a long absence of dismantling or, on the contrary, they can wear out with a large number of turns of the gander.

Cranes

The cheapest sink faucets from common solutions are equipped with screw cranes (taps) with rubber gaskets. The water opens and closes with several turns of the lamb (handles). Alas, low price does not mean the practicality of products: gaskets lose elasticity over time, and soft brass screws wear out quickly with considerable effort.

Products with ceramic taps - in the modest opinion of the author, the best sink faucets. Water overlaps due to the reciprocal rotation of ceramic plates with ground surfaces by 90 degrees. This production version allows for very precise adjustment of pressure, temperature and virtually unlimited resource.

However: any mixers with ceramics require coarse filters at the entrance to the apartment or house. Sand and scale, trapped in the groove of the plates, can jam Kranbuksu, and with considerable effort - and destroy it.

Finally, single lever faucets allow you to adjust the pressure and temperature with one hand, which is convenient when washing dishes. The adjustment here is ensured by the mutual displacement of the ceramic plates, but with a somewhat more complex configuration.

Materials

What are faucets made of?

Exotic

Just for completeness of coverage of offers of the market we will mention some unusual mixers for a sink.

• Products with photovoltaic cells supply water at the approach of hands.. They are very expensive and non-repairable in living conditions.
• Thermostatic sink faucet allows you to set the required water temperature in degrees. A thermostat dosing the ratio of hot and cold water can be electronic and mechanical.

• The device with integrated flow heater is connected only to cold water.. Against the background of the construction of a conventional mixer and a separate storage or instantaneous water heater, it is interesting for its compactness.
• Classic style sink faucets are stylized as retro exclusively. Inside it is convenient and reliable modern devices. Styling is the coating under the old bronze and deliberately massive sheep.
• Kitchen faucets with shower heads are quite comfortable., when there is a need to rinse the notorious large pot or wash the fruit.

Waivers

What most often fails in the products we are interested in?

Flexible hoses

Their service life rarely exceeds 5 - 7 years.

Over time, the rubber core due to liming loses elasticity and begins to crack.

The problem is eliminated by replacing both hoses:

1. Water overlaps.
2. Unscrew the union nuts of the hoses.
3. Removed washing.
4. Old hoses are unscrewed from the body and replaced with new ones.

Attention: it is impossible to twist the hoses, holding them by the braid. This is done only with a small adjustable wrench or narrow pliers beyond the edges on the switch. In addition, the pipe thread of the hose is better to additionally reel with tape FUM or polymer sealing thread.

1. The design is going in the reverse order.

Kranbuksy

The instructions for repairing cranes that have ceased to stop water depend on the type of cranes and malfunctions.

• On screw kranbuksu dripping in the closed state, it is usually enough to replace the gasket. For replacement in plumbing stores special repair kits are sold.

However: before going to the store, open the tap a couple of times to full capacity and close it again. The cause of a malfunction may be a piece of scale stuck in the housing.

• A screwed crankbuku and ceramic spouted out when attempting to turn it when the scale got into the plate cutout can be repaired with your own hands only if there is a donor tap with a different breakdown. Usually it changes to analog.

Cartridge

Continuing to discuss the design and repair of sink faucets - the single-lever faucet most often ceases to shut off the water due to cartridge breakage. Along with ceramic plates with sharp leaps of the lever, their plastic retainers often break.

How to replace the cartridge?

1. Shut off the water.
2. Remove the decorative cap from the bottom or side of the lever.

1. Turn off the screw under it. It can be under the usual screwdriver or hex.
2. Remove the lever.
3. Turn off the decorative nut.
4. Twist and change the cartridge.
5. Repeat the operations in the reverse order.

Filter

The goose filter aerator often causes a drop in water pressure. It is enough to disassemble and clean out all the pollution.

Conclusion

We hope that our material will help the reader in choosing the mixer and solving most of the problems associated with it. The video in this article will traditionally offer additional information. Successes!
