At this time, due to the time, materials, construction and other reasons, the plug is not easy to remove, often mandatory demolition, so the pipeline, especially in the interface area greater damage. Buried decoration basic end rework the difficulty and economic losses, rework reluctant to use tube interface parts of seepage, leakage is inevitable, there will be a common wall paint discoloration, blistering, loss, contrast contact moldy wood board paint off. Damage to the faucet, you need to turn off households into the shut-off valve to be replaced the damaged faucet is removed, the water in the pipes will be a loss, water for other parts of the pipeline system, after the re-installation of the faucet also open into the family after the cut-off valve to the water, resulting in the loss of time, if it is a high-level public spaces, resulting in loss of time, inconvenience, waste of water resources will be even greater.3 way air valve
