About This Project

This guide provides detailed instructions for installing an ADA-compliant protective shield over the hot water and drain pipes beneath a sink. The process involves preparing the area, measuring and trimming the shield components, and securely attaching them to the P-trap, water supply lines, and shut-off valves to prevent contact, burns, or abrasions, ensuring compliance with accessibility standards.

Common Problems

Leakage Test: Insert the plugs for a water test. Ensure there is no leakage at any joint.

Solution: To avoid this issue: Be mindful of this warning and take appropriate precautions.

Hidden leaks behind walls cause water damage and mold if not detected early.

Solution: It's best to leave the water on for several minutes and check for slow leaks before closing up the wall.

Water can spray unexpectedly from new connections, causing damage or injury.

Solution: Have a second person inside to watch the new connections for leaks when you first turn the water on.

Unnoticed small leaks can cause water damage.

Solution: Placing a dry paper towel under the connections can make it easier to spot very small drips.

Hand-tighten connections first, then give them a final quarter-turn with a wrench to avoid over-tightening and cracking the plastic nuts.

Solution: To avoid this issue: Be mindful of this warning and take appropriate precautions.

Cross-threading and damaging plastic drain fittings.

Solution: Hand-tighten all plastic drain parts to avoid cross-threading, then use channel-lock pliers for a final quarter-turn if needed.

Do not overtighten the water supply line nuts, as this can crack the plastic fittings or damage the rubber gasket, causing a leak.

Solution: To avoid this issue: Be mindful of this warning and take appropriate precautions.

Frequently Asked Questions

Why is installing an ADA-compliant under-sink shield important, and what does "ADA-compliant" mean in this context?

This shield is crucial for preventing contact with hot drain pipes and sharp edges, protecting individuals, especially those using wheelchairs, from burns or abrasions. "ADA-compliant" means it meets specific requirements for clear under-sink space and protection, ensuring accessibility and safety for all users.

The most challenging part is often precisely measuring and trimming the shield components to fit your specific plumbing configuration. Unexpected issues like corroded pipes, tight spaces, or needing to replace an old P-trap can extend the estimated 3-hour completion time. Always double-check measurements before making cuts.

You primarily need basic tools like a utility knife for trimming the shield, a measuring tape, and a marking pencil. While a pail is essential for catching water when working with the P-trap, no highly specialized plumbing tools are typically required if your existing plumbing is in good condition and only needs a shield.

Common mistakes include inaccurate measuring leading to ill-fitting shields and not securely attaching all components. To avoid this, meticulously measure twice before cutting, dry-fit the shields before final attachment, and ensure all straps or fasteners are tightened properly according to the manufacturer's instructions.

Always turn off both the hot and cold water supply lines under the sink before beginning any work, and have a bucket or pail ready to catch residual water from the P-trap. Wear appropriate safety glasses to protect your eyes, especially when cutting materials with the utility knife.

Most ADA-compliant shields, like the TRUEBRO LAV GUARD, are designed to be trimmable and flexible to accommodate various pipe configurations. If your plumbing is exceptionally non-standard or severely corroded, you might consider upgrading to a standard P-trap (like the Insta-Plumb PVC P-trap) for an easier and more secure shield fit.
