A plumbing access panel provides easy access to plumbing-system elements behind the wall, such as a shut-off valve, drains, etc., by way of a panel or door. This cost-efficient and time-saving panel or door can be easily opened or removed, eliminating the need to break through and repair the drywall each time access is needed. 
This access is vital to keeping your plumbing system healthy — and not just when a repair or shut-off is needed. Regular plumbing maintenance is necessary for the system's health, and plumbing access panels allow ready access whenever the system needs a clean-out or inspection. 
Installed between wall studs, plumbing access panels can be flush or surface-mounted within the drywall during construction or a rough-in. The panel can be located behind a bathtub, shower, or even in a closet.
