5. The closing of the screw-stabilized rubber faucet is not complete. Usually, it is only necessary to remove the handle (handwheel) when the hard object is stuck in the sealing port. After the bonnet and the valve core are removed, the impurities are removed. It can be restored to normal use when it is installed as it is.
6. If the closing of the ceramic valve plug sealing nozzle is not complete, the hard surface may scratch the sealing surface or the pre-tightening force applied to the valve core is insufficient. If it is the former, it can only be repaired by the after-sales service department or professional maintenance department of the faucet production plant. In the latter case, the user only needs to remove the handle (handwheel) and then tighten the spool slightly.
7. There are two reasons for the looseness of the handle (handwheel) First, the handle (handwheel) is not fastened due to negligence during assembly, just tighten the fastening screw. Second, the handle (handwheel) is poorly selected, which occurs mostly due to premature oxidation of the zinc alloy handle (handwheel) and the valve core connection, causing an increase in clearance due to corrosion, and generally there is no remedy. Therefore, do not use zinc alloy handles (handwheels) as much as possible.
8. In case of leakage at the connection point of the nozzle, it is usually caused by the fact that the assembly part is not tightened, just tighten it. Sometimes, a faucet is perfect in every aspect, but there is a feeling of dripping after closing. At this time, it depends on the length of time of dripping, whether the dripping water does not stop and the amount of water drops. Longer drip times can sometimes last for 4 or 5 minutes, with a total of about a dozen drops. The amount of water dripping is equivalent to the residual water in the mouth of the nozzle after the water source is turned off, which is a normal phenomenon.
