leak at connection to drain pipes and Holding tank

I have a small leak at the connection to drain pipes and the Holding tank that leaks when I drain a sink. What kind of connection is between the drain pipes and tank. I can unbolt the tank and drop it...

robrv3, the better way to test the plumbing is to fill your sink as full as you can possibly get it with water and then unplug the drain and watch for leaks. This will make a lot of difference in your results.


I filled the sink to the top 3 times then pulled the sink plug and no leak. Before anytime a sink was draining a little water would leak
