How to drop a gray water tank

[dinsprings]

I have a leak somewhere above my gray water tank and am trying to drop the tank so I can find it. Anyone know how to drop it? The front bracket bolt can't be removed because there's not enough clearance to pull the bolt out (the head is on the tank side). I have a 08 Itasca Navion 24H on a 07 Sprinter chassis. The leak used to back water up onto the floor but now all the water runs out on the ground - went camping for 3 days and did not have a drop of gray water when I got to the dump station. Any ideas?

If you go online to Winnebago's website they have very helpful diagrams that show everything in detail, and you will most likely find your floor plan and can see how the tank is attached. Also look into whether there is a check valve at your shower drain, or an actual trap. sometimes those valve types can be problemmatic.

You want to go here and click on 3D Service Parts Lookup. Then follow the year/make/model to your diagrams.
