SEWER OVERFLOW RELIEF DEVICE |
摘要 |
<p>A sewer overflow relief device for mounting at a top end of a sewer overflow relief pipe includes a top cover having at least one outside air intake and an air flow control mechanism for controlling the flow of outside air into the sewer overflow relief pipe. In use, the device prevents outside water from entering the sewer and the device may be ejected from the sewer overflow relief pipe by sewage pressure pushing against the device, thereby allowing the sewer overflow relief pipe to overflow.</p> |
