I have discovered that when weight is placed on 'seat' portion of the shower pan in our 84 310 MH the shower pan deforms slightly and opens cracks in the caulk which seals the shower pan to the base of the shower walls.
When I noticed the cracks in the caulk I re-caulked. Now I see that the new caulk is cracking as well.
I don't know if the problem is the caulking job I did or the deformation of the shower pan. When I place weight in the center of the 'seat' (by leaning on it with my hand) it doesn't move much but it does deform and pull the edge of the pan away form the shower wall (1/8 inch or less).
What are your thoughts and/or experience?
How difficult is it to remove the shower pan to inspect under it?
