It is common to use a casing when making a pool, which is the passage of the pipe to the pool. However, the ordinary casing is difficult to seal, so that there is water leakage between the casing and the pipe, and water leakage between the casing and the wall.
Only waterproof casing can solve the water leakage between the casing and the wall, but it can not solve the sealing between the casing and the pipeline. The flexible waterproof casing can solve two problems.Casing can be divided into: ordinary casing thicker than the pipe to be used, fixed in the wall or plate, through which the pipe passes.
The flexible casing - that is, the sealing between the casing and the pipe with a flexible material to seal. Rigid casing - that is, the casing and the pipe are sealed with a rigid material to achieve a sealing effect.
Waterproof casing--that is, the environment used for the casing is to prevent liquid from leaking or leaking such as pool, septic tank, basement, that is, the waterproof wing with no less than one turn on the outer wall of the casing. When the pipe is poured into the wall, it becomes a whole, and there is no leakage due to the expansion and contraction factor.
