The last time I dumped the black tank I got a burp when I did a power flush (fill bowl to top and flush). The gauge reads one light (empty). It is still burping when half full of water. I believe my options are to either use a long rod or shove a hose down the vent stack and see if the bottom of the vent pipe is fouled. I will check the vent cover in the morning to see if I have birds or spider web plug under the cap. Any other suggestions will be appreciated..
