How do I get to the plumbing in 5er???

[lockdoc]

Hey all- If there are any other DIY types out here, I am wondering if you know how to get to the plumbing behind the storage compartment wall in the basement? I am thinking that I will have to remove the wall to crawl back there.

I just found out today that the water leaks I took the 5er to dealer to fix were not taken care of as told!!! I am going to insist that the dealer now comes to me or reimburses me for my labor to correct this myself as we are two hours apart. The black tank flush line is putting more water into my basement than it is into the black tank!!

Any ideas that would save me some hassle.......I'm all ears.

Thanks,

Kevin
