CAUTION, "NON-STANDARD"!

Choosing a heater tap in the store, be careful - it is quite possible that it will turn out to be worse than the regular one.

The faucet of the heater "Zhiguli", "Niva" and "Oka" we, car repairmen, not without reason relate to consumables. Like it or not, but after two or three years of operation it will fail - the diaphragm that has lost its elasticity breaks, and the hot “Tosol” is not even a trickle, but a storm flowing onto the passenger’s legs.

The "experienced" problem has long been resolved - they put on the "Zhiguli" "Moskvich" or "figure eight" crane, taken out of the cabin under the hood (ZR, 1998, No. 10). Car service workers rarely engage in such creative work - only on special order from the client. Usually they just change the tap to a new one, which normally takes no more than 40 minutes. Those who care about the welfare of their customers do not buy faucets anyhow, but proven ones - Daazovsky or Osvarovsky similar in design and quality (photo 1), be sure to remind the owner that after two years it needs to be replaced - prophylactically.

For those who took the car for a long time, I recommend a more expensive faucet of the Moscow factory of ceramic products (photo 2). It is very reliable, and it’s nice to manage it - the lever moves gently, without jamming. Among non-standard products of this kind, this is one of the few successful ones, more often grief-inventors put into production completely “raw” constructions unsuitable for long-term operation.

Such, for example, is the spool valve from Samara for 40 rubles, which is now littered with all the shops and markets. No, it does not flow - everything is in order here, but after six months it will still have to be thrown away. The authors of this masterpiece, having copied a “samovar-type” crane from trucks, decided to save money and made their version not of brass, but of aluminum alloy, both the body and the cylindrical spool. Before the winter season ends, the corrosion products, expanding in the gap, tightly block both parts into a single unit - the crane will remain either open or closed. There is no question of stirring it up with a lever - just sawing the case, you can knock the spool with a hammer (photo 3).

To summarize, I will advise motorists to carefully choose non-standard spare parts (this is not just about faucets). If there is the slightest doubt, it is better not to experiment and buy a unit from the manufacturer that supplies the parts to the conveyor - in any case, the result will be predictable …

The diaphragm faucets of the DAAZ or OSVAR plants "run out" violently and without a preliminary call. The price is about 50 rubles.

A crane with metal-ceramic valves - the price is 85 rubles. It does not have a shoulder or undercut on the flanges, so thick gaskets and sealant will be required during installation.
