I was wondering if any of you had any suggestions before I drop the grey tank so I can see the underside. All of a sudden we have a little flex in the floor in the bathroom. I took off the access panel by the tub and there is no water damage and the floor itself is in great shape it just flexes about 1/4" in an area about 2' x 1' between the tub and toilet. I don't know if a fastener came loose or if there is a shim that popped out or what, any suggestions?? Thanks so much in advance.
