Shredded Grey Tank Insulation

Has anyone ever dealt with replacing the insulation around the gray water holding tank?  Mine got shredded from my Alaska Road trip and the many gravel roads.  Any help would be appreciated

Hi.  I had a similar issue along the bottom and 1 to 2 inches up the sides of my tank.  I trimmed of all of the loose pieces with good scissors.  Then a couple of rolls of 4" waterproof gorilla tape did a very nice job.  Really good stuff to have around, thick and very sticky.   First I overlapped layers to cover the bottom length of the tank to fully cover and run up the sides two to three inches.  Then I finished off with lengths to fully encircle and cover the end pieces of the initial bottom strips.  Because of the tape thickness it will add insulation as a bonus.  Flex seal has a similar product. Take your time, did I mention it was sticky.   Tom.

For what it's worth... I simply removed the insulation on both Grey and black tanks.  In MY mind, the insulation really serves no purpose.  That's because the drain lines aren't insulated.  I have been on a few trips where it got as cold as 7 degrees and the drain lines still froze even with the tank heaters on.   Thus, I couldn't drain the tanks anyway.  Once it got above 20 degrees, then the drain lines were OK, but that was almost 1,000 miles down the road.    That was with the insulation in pace.

The tank heaters still work, they are under the insulation, so removing the insulation doesn't matter.

That's my view anyway.  Others views may vary.

When replacing my black tank valve last year, I noticed the tank insulation was starting to separate along one edge.  A cleaning followed by a strip of Duct tape took good care of it.  Because of the time of year we use our PC, I will likely never use the tank heaters, but I maintain unused features regardless because you never know when you will need them......and it's a good selling feature that everything is always kept in good order.
