Quality problems that should be paid attention to

1) The toilet is uneven and tilted left and right. Reason: In the process of stable installation, the front and both sides of the pad brick were not firm, and the high water tank was not aligned with the toilet, because the cinder was not inspected and repaired after filling.

2) The dragging of high and low water tanks is not flexible. Cause: When installing the internal fittings of high and low water tanks, the positions of the three main components in the water tanks are unreasonable. The water inlet and handle of the high water tank should be placed on the same side of the water tank. So as to avoid mutual interference during use.

3) The chrome-plated surface of the parts is damaged. Cause: Use pipe tongs during installation. Use a flat wrench or a homemade wrench.

4) The toilet bowl is not aligned with the center of the rear water tank, and the elbow is crooked. Cause: the line is not in the center, the toilet is not installed correctly, or the box is stabilized first, and then the toilet is off the ground. Cause: The sewage outlet was reserved too high, and it was not repaired before it was installed stably.

6) The gap between the vertical urinal and the wall is too large. Cause: The size of the sling is not accurate.

7) sanitary ware overflow failure. Cause: There is no overflow hole at the lower outlet.

8) Before water supply, clean the dirt in the appliance. Hydropower installation specifications come from national standards and industry standards, mainly including:
