How do I access the gas valve so I can convert to LP. There is no access in the front. Model #MDG5500AWW. Thanks Warden

I am looking for some helpful ideas. Here is the situation. We've just remodeled our kitchen, which included getting a new sink. The new sink is quite a bit lower than the old one. In addition, we also installed an RO water system (don't know if that matters). Ever since, we've been having problems with the sink draining very slowly. Never had this problem before remodeling. I had a plumber in, and he used a power snake and a water pressure hose, which helped but only for a couple of weeks. There is also a garbage disposal in the setup, but we had it before remodeling too. We're very careful with what goes down the drain, and almost never use the disposal (there is no need to). The plumber claims that our drain pipe (which runs about 25 feet from one end of the house to another) must not be pitched enough. We can't see the pipe since it's between the floor and the basement ceiling, but he claims that could be the only reason, and there can't possibly be enough room for a proper pitch for such a long run. In addition, we apparently don't have a proper vent, so we've always (before and after remodeling) had an AAV. (Actually, there is a vent on the roof just above the kitchen, but it appears that it might've been disconnected at some point by previous owners -- is there a way to check that?) It does sound plausible, but the pitch of the pipe was no different before remodeling (we didn't touch it) -- how come it worked fine for years then? I don't want yet to be opening the basement ceiling to see what's going on with the pipe. Is there anything else that could be done? Any ideas, why after getting a new sink we would be having this problem? Thank you in advance! David:help:
