该怎么做

To safely clear a blocked sewer or septic line

  1. Determine if the blockage is within the walls of your home. Only outdoor blockages pose a risk.
  2. If you think the blockage is outside, ask your plumber to call PSE at 1-888-225-5773 at least one hour before attempting to clear it. We'll immediately dispatch a technician, who can usually arrive at your location within 60 minutes.
  3. Our technician will work with your plumber to locate the sewer and gas lines and make sure it's safe to proceed. This service is free of charge.

你的水管工可以帮忙

Your plumber or drain-cleaning professional may recommend inserting a camera in your sewer to look for cross bores. This is a good practice and if a cross bore is found, PSE will reimburse you for the camera inspection. 然而, you should always call us to work with your plumber to precisely locate both your sewer and gas lines before using a cutting tool. It’s possible that a cross bore could be concealed behind other obstructions and may not be visible to the plumber's camera.

  • 交叉钻孔事实
    什么是十字孔?

    If natural gas was installed in your neighborhood without digging trenches, a gas pipeline may have been inadvertently inserted through a sewer or septic line, even for homes without natural gas service. This is called a "cross bore".

    Cross bores are safe unless they become damaged by cutting tools that clear blocked sewer and septic lines. Rupturing these pipelines would allow natural gas to enter your home and endanger your safety.

    交叉钻孔是如何发生的

    多年来, utilities nationwide have installed gas pipelines by boring underground rather than digging trenches, to avoid tearing up paving and landscaping. Existing underground pipes and wires are marked before work begins, whenever possible.

    然而, sewer and septic lines may go unnoticed because they're not regularly mapped and are undetectable using above-ground locating devices. Cross bores are a rare side effect that occurs when the machine used to install gas pipelines inadvertently bores through sewers, leaving the gas pipelines vulnerable to damage by cutting tools.
