C26 waste tank leak

[goletamoby]

I’ve developed a small leak in the water tank, seems to be on the backside starboard side. Notice when we run it and can see water trickling down the hull to the bildge. Is there any troubleshooting that can be done without having to remove the whole tank to get on the backside of it to work on it?

Check fittings. Can't figure out where leak is, tape paper towels at suspect places and see what is wet in a few days.

I should clarify, it mostly seems to leak when flushing and under pressure.

If you say flushing, i assume your toilet uses fresh water, not like older tugs that use saltwater. Are you positive it is the water tank? Not rain water, air conditioning, etc.? Does your water pump ever randomly run. If not something, else might be leaking. Leave your water pump on all the time just to see if it randomly runs. Some people leave the water pump on all the time anyway.
