| We have a Liberty sewer pump system installed in our basement bathroom, and it has been in use for about 8 years. We haven't had any problems until recently. Now, when the lift station turns on and begins pumping, it causes problems in the bathroom on the main level of the house which is directly above the bathroom. I get large air bubbles in my toilet and can hear gurgling in the shower drain. What would cause this?
Thanks! |

| Incorrect venting. Pump pits require there own dedicated vent line not shared with anything else but run directly to free air. |

| It has its own dedicated venting and no obvious clogs since everything drains quickly -that is what has us puzzled. |

| You have described something simply not possible. The venting is shared at some point, or the pump is generating a whole lot of back presre in the drain and is not vented correctly. If the venting was correct there could be no way to make a bubble come from a toilet with an ejection pump. |

| The Liberty pump station has it's own dedicated vent up from the buried tank and the main level bath vents out into attic area. The pump station and main level bathroom do share a drain line to the septic tank, with the main level bath being closer to the septic tank. |

| When was the last time your septic tank was pumped? |

| Where and how is the lift station connected to the house DWV system? |

| Thanks. Didn't even think about septic being full. I am not aware that it has been pumped in the 9 years I have lived here. |

| A septic tank is always full and pumping the septic tank will have nothing to do with the problem at hand. |

| I just know that when my parents had trouble with sewage backing up--it was because the septic needed servicing. My thought was that if the "troubled" drains are closer to the septic tank than the other, perhaps the tank is nearing a service time. If it hasn't been serviced in over 9 years, it is probably time to do so, regardless of whether it solves your problem or not (and if it solves the problem, BONUS!) (Report back?) |
