How to Install an ADA-Compliant Under-Sink Plumbing Shield · Step 6 of 6
In this video
With all pipes connected, perform a critical leakage test before finishing the wall. Remove the protective plastic cover, temporarily install the valve cartridges and knobs, and insert plugs or caps on all three outlets (rainfall shower, handheld, tub spout). Turn on the main water supply to pressurize the system. Carefully inspect every joint and connection for any signs of water leakage. This step is vital to prevent water damage inside the wall.
Goal: Check for leaks in the plumbing system
- Leakage Test: Insert the plugs for a water test. Ensure there is no leakage at any joint.

FAQs
Is installing an ADA-compliant under-sink plumbing shield truly a beginner-level DIY project, and how long should I expect it to take?
Yes, this project is considered beginner-friendly as it primarily involves precise measuring, careful cutting, and straightforward attachment. Most installations can be completed within 1-2 hours, assuming all tools and materials are prepared. Taking your time with measurements and test fits will prevent re-work.
What are the most crucial safety precautions I should take when working on under-sink plumbing, especially to prevent burns or water damage?
Always turn off the hot and cold water supply valves to the sink before starting any work to prevent unexpected leaks or sprays. For protection against potential burns from hot pipes, wear gloves and allow any hot water in the lines to cool down if possible. Keep old towels or a bucket handy to manage any residual water in the P-trap or supply lines.
The project lists specific tools like the Husky Pro Utility Knife and materials such as the Columbia Forest Products Plywood Project Panel. Are these exact items essential, or can I use similar alternatives?
While a sharp utility knife and a reliable measuring tape are essential for accurate cuts and measurements, the specific plywood panel is likely intended as a source for custom fabricating the shield. You can use any durable, heat-resistant, and non-abrasive material suitable for cutting and shaping. Alternatively, pre-formed ADA pipe wraps or shields are widely available and often easier to install.
What's the most common mistake when installing these shields, and what if the trimmed shield doesn't fit perfectly around the P-trap or supply lines?
The most common mistake is inaccurate measuring and cutting, leading to gaps or an improper fit. Always 'measure twice, cut once,' and make small, incremental cuts. If the shield doesn't fit perfectly, small gaps might be tolerated if the pipes are still fully covered, but significant openings compromise ADA compliance and may require a new piece of material or a suitable heat-resistant sealant for minor adjustments.
