I am in Baja Calif, Sur, Mexico. I need to join 4 inch Sanitary PVC ( very thin) to 3 inch ABS using a 4 inch/3 inch reducer. The reducer's 3 inch portion does not quite fit an ABS coupling, but it's close. Should I use ABS cement or PVC cement? I plan on filling the void between the ABS coupling and the PVC with latex/silicone calk. The only cement I have access to is either PVC or ABS cement ( I have both). Thanks.
