How to Install a Plumbing Access Panel for Future Repairs · Step 6 of 7
In this video
Position the panel on the wall, starting with the first panel in the corner. Angle the panel at approximately 30 degrees, insert the tongue-and-groove edge into the previous panel (or corner), and carefully push it flat against the back wall. Press firmly across the entire surface to remove air bubbles, then use a rubber mallet to lightly tap the panel from top to bottom to ensure it's tightly connected. Use shims at the bottom if needed to align the top edges of the panels, and remove them after the adhesive has cured.
Goal: Mount panels onto the wall
- While installing the wall panels, make sure the top edges all line up. You may need to shim the panels to create a seamless look.
- Remember to remove the shim once the wall panel has dried and is secured to the wall.
- If using the mallet to tap, do not hit the tongue and groove.

FAQs
How can I ensure I don't cut into pipes, wires, or studs behind the drywall?
Always use a reliable stud finder (like the DEWALT DW0150) to scan the area for studs, electrical wiring, and plumbing lines before marking your cut. After marking, make a series of small, shallow pilot holes with a drill or jab saw to visually confirm the cavity is clear before making your main cuts. If you hit an obstruction, stop immediately and reassess.
Where is the ideal location to install a plumbing access panel?
Install the panel directly over the specific plumbing components you need to access, such as shut-off valves, cleanouts, or fixture P-traps. Choose an area that provides sufficient working room behind the wall once the panel is open. Ideally, select a spot between two studs to avoid cutting structural elements, confirmed with your stud finder.
What if I accidentally cut the drywall opening too large for my access panel?
If the opening is slightly oversized, you can often compensate by applying a thicker bead of construction adhesive (like Loctite Power Grab Express) and caulk around the panel's flange to fill the gap. For larger errors, you might need to patch the drywall with a repair kit and recut, or purchase a slightly larger access panel to cover the mistake. Measure twice, cut once to avoid this common issue.
Can I use a regular utility knife for cutting the drywall, or is a jab saw necessary?
While a utility knife (like the FASTCAP Triblade) can be used for some straight cuts, a jab saw (such as the Milwaukee Folding Jab Saw) is highly recommended for this project. It provides better leverage and control for cutting through drywall, especially for internal corners and thicker sections, resulting in cleaner and more precise openings.
