The dragon's head is blocked.

  1, the quality problem of the faucet: off the total valve, change a faucet.

  2, scale blockage: Remove the tap, pour some hydrochloric acid into it, rinse. If there is no hydrochloric acid, you can use white vinegar to soak the scale and continue to use it.

  3, foreign body blockage: the interface below the basin is opened with a wrench, the faucet is inverted, and a bottle of water is poured into the inside. If the water flowing out at the back end is not smooth, it proves that there is foreign matter in the faucet tube. If it is blocked at the pipeline, you can take the high-pressure water mode of the shower head with a shower. If the foreign matter is larger and more stubborn, you can use a hard wire to insert the faucet to clear it. If it is a faucet joint, it is usually called a faucet, and it is blocked at the position where it is in contact with the countertop. It is necessary to find a thin steel wire and make a hook at one end to slowly hook out the foreign matter. After the treatment, the faucet is poured into the water. This washing process can flush out the small debris that has just been smashed out to ensure that the debris is completely drained.

  Tap is leaking

  The faucet still effluent after the spool is closed

  In this case, it may be the reason that the pressure cap is loose or the rubber ring at the bottom of the valve core is deformed. For the former, it is recommended to remove the handle and the decorative cover and re-tighten the pressure cap. In the latter case, it is recommended to take out the valve core. Check the condition of the apron and reinstall it.

  Water seeps from around the spool

  If this phenomenon is likely to be loose or misaligned, it is recommended to remove the valve plug and reinstall it once.

  Water seeps from the middle of the spool

  If you encounter the above phenomenon, it means that the spool is damaged. At this time, it is recommended to replace the spool.

  Water leaking at the bottom

  This phenomenon may be caused by the O-ring of the inlet pipe not being installed or deformed. It is recommended to unscrew the hose to see if the O-ring is loose. If it is loose, reinstall it. If the O-ring is found to be deformed, it is recommended to replace the O-ring.

  Waterproof tape is damaged

  Tighten the faucet and then use a wrench to remove the faucet counterclockwise. Then use a threaded hole to wind the tape back six times in a clockwise manner. After making it, re-tighten the faucet and then open the switch. There will be no water leakage.

  Faucet at the joint of the faucet

  Loosen the cap nut of the faucet and retighten it or replace it with a new u-ring.

  The bolt gap of the faucet seeps

  Once the faucet seepage and dripping problems occur, they are related to the gasket. Remove the faucet to see if the gasket is detached or worn, and it can be repaired in time.

  Constant temperature water dragon head maintenance

  The water is hot and cold

  In this case, you need to see if the water is continuous or intermittent. If it is continuous, it is necessary to reduce the pressure of cold water or hot water (which pressure is greatly reduced). If it is intermittent, check whether the temperature of the hot water is too high. If the hot water temperature is high, adjust the handle of the thermostatic valve core, adjust the handle to the low temperature direction, and adjust it to 34-36 °C. If it cannot be solved, replace the valve plug.

  No hot water

  No hot water is produced above 38 °C. There is no water entering the valve body, the water inlet is blocked or there is residual cold water in the pipeline. Treatment: Wash the clothes filter gasket or drain the cold water in the hot water pipe.

  The water is not hot above 38 °C, check whether the temperature of the hot water has reached 55 °C or above, check whether the pressure of the hot water is low (this is the case for users in the bungalow and the top floor). Treatment: increase the temperature of the hot water, adjust Cold water pressure.

  The only problem is that the water in the hot and cold water is reversed. Just change the water inlet.

  Water dragon head

  1. After the tap water is deactivated for several hours, be sure to open the faucet for 1 to 2 minutes before use. Do not drink overnight tap water from the tap.

  2, many families now have hot water supply, but it is best not to use it as drinking water or cooking, because the content of lead in hot water is many times higher than cold water.

  3. When purchasing faucets, be sure to choose products with lead content, choose products that have passed the safety certification of China Quality Certification Center or choose famous brands of sanitary wares, because brand manufacturers have a strict quality control program, raw materials and processes are compared. Protection.

  4. Install the water purifier.
