After-sales Problems and Service Instructions for Concealed Shower Sets and Faucets

To safeguard user experience, standardize after-sales service procedures, and promptly resolve various problems arising during the installation and use of concealed shower sets and faucets, Wenzhou Yiya Sanitary Ware has established a comprehensive after-sales service system. We have clarified solutions to common after-sales issues and official service standards, and provide professional, efficient and thoughtful after-sales support for customers throughout the whole process. Details are specified as follows.
shower set Leakage Problems (wall seepage, joint leakage, water outlet terminal leakage)



Common Causes: Unstable hot-melt connection of pre-buried pipeline joints, aging valve core seals, damaged sealing rings at water outlet terminal joints, and poor sealing of pre-buried boxes.

Solutions:① In case of wall seepage, shut off the water inlet valve immediately and contact after-sales staff for on-site inspection to locate the leakage point (pipeline joint or pre-buried box). We will re-weld pipelines or replace sealing parts and repair the wall.② For joint leakage, users may check whether the sealing ring falls off or is damaged. If damaged, please contact our after-sales team to obtain a matching sealing ring for replacement. On-site maintenance will be provided for problems unable to be handled by users themselves.③ Leakage at water outlet terminals is mostly caused by aging sealing rings. Our after-sales technicians will replace sealing rings or water outlet terminals free of charge within the warranty period.


Common After-sales Problems of Faucets

Faucet Dripping (continuous dripping after closing)

Common Causes: Wear of ceramic valve core, aging sealing ring, loose valve core, blocked water outlet.

Solutions:

• If caused by valve core problems, our after-sales technicians will conduct on-site inspection and replace the original ceramic valve core free of charge within the warranty period.
• Aging sealing rings will be replaced at no cost.
• Loose valve core will be re-tightened and adjusted by our after-sales staff.
• For blocked water outlet, please disassemble the aerator and clean impurities with clean water. Please contact our after-sales service for assistance if you cannot handle it independently.
