| Ok I've had it I cannot get the sinks to drain the tanks bone dry, there's no roof vents only for the shower, the bathroom sink and shower drain fine. The only way I can get the kitchen sink is to unscrew the vent under the sink witch is new also about a month old, is it possible that there's dried up junk at the bottom and needs knocked loose? I'm at a loss here. |

| I haven't yet but would it be clogged if when I unscrew the new vent it will drain? |

| My other question is that I have only one roof vent, is it possible it vents all three holding tanks? I have one tank up front that is solely for the kitchen sink and one tank for the shower and bathroom sink, and then the black water tank. |

Location: Los Angeles, Ca. | Each tank should have its own vent. If the sink tank is not vented properly, the sink won't drain as well as it should. Clean the trap first. If it still doesn't drain properly, try draining the sink with the tank drain open. If it then drains properly, you"ll have to figure out how to vent the tank or live with the slow drain. |

Location: Los Angeles, Ca. | ????? Just make sure air can flow into the top in the direction of the water flow. Should take very little pressure..there is just a small spring pushing on a rubber diaphragm which is supposed to keep out the holding tank fumes and let air in as the water is flowing. |

| Hmm I wonder if the small holes in the cap are not adequate, wonder what drilling larger holes on the sides would do |
