Maintenance knowledge

A. During installation, various impurities in the pipeline shall be completely removed to avoid damage, jamming, blockage and leakage of impurities to the valve core. At the same time, the surface of the faucet shall be cleaned in time so that there is no residue of building materials left.

B. For any kind of faucet products, it is not necessary to use too much force on the handle when switching, just gently twist or toggle the handle. The products with tap outlet and screen cover shall be disassembled and washed after being used for a period of time to remove impurities. For products equipped with hoses, care should be taken to keep the hoses in a natural stretch state to avoid breaking.

C. The surface of the faucet should always be lightly wiped with a clean soft cloth dipped in a little detergent. It is prohibited to use metal wire balls or cleaning cloths with hard particles. In addition, do not collide with hard objects to damage the faucet surface.

D. Water faucets that have not been used for a long time sometimes have problems such as incomplete closing, leakage, loose handle, loose connection port, etc. Generally, consumers can solve the problem by themselves. If the screw type rubber seal ring faucet is not completely closed, it is usually because the seal is stuck by hard debris. At this time, just remove the handwheel and unscrew the valve cover, clean the impurities around the valve core, and then install it as it is before normal use. If the sealing water nozzle of ceramic disc valve core is not completely closed, the sealing surface may be scratched by hard debris or the preload applied to the valve core is insufficient. In case of the former, the faucet can only be sent to the manufacturer's after-sales service department or professional maintenance department for repair. For the latter, the user only needs to remove the handle (handwheel) and then slightly tighten the valve element.

E. There are two reasons for the loosening of the handle (handwheel): first, the handle (handwheel) is not fastened properly due to negligence during assembly, and only the fastening screws need to be tightened. Second, the selection of handle (handwheel) is poor, which is mainly caused by premature oxidation and corrosion of the connection between the handle (handwheel) and the valve element, resulting in increased clearance, and generally there is no remedy. Therefore, do not use low-grade faucets as much as possible.

F. In case of leakage at the connection part of the faucet, it is usually caused by not tightening during assembly, and only needs to be tightened. Sometimes, a faucet is perfect in all aspects, but it drips constantly after it is closed. At this time, it depends on the duration of dripping, whether the dripping is continuous and the number of water drops. The longer dripping time may sometimes last for 4 or 5 minutes, and the total amount is about ten drops. The amount of water dripping is equivalent to the residual water in the faucet mouth after the water source is closed, which is a normal phenomenon.

G. After using for a period of time, if the water output is reduced, or even the water heater turns off, the filter screen of the faucet may be blocked. Gently unscrew the bubbler at the water outlet of the faucet, remove the filter screen cover, and remove impurities. Generally, it can be restored as new.

H. As long as they are used properly and maintained in time, high-grade and high-quality faucets will remain as new for a long time.
