Once all plumbing connections are made, turn the main water shutoff valves on slowly. Open the faucet and let the water run. Carefully inspect all the connections—where the supply lines connect to the valves and the faucet, and all the joints of the P-trap and drain—for any drips or leaks. If a leak is found, turn off the water and gently tighten the connection. Place a bucket or towel underneath to catch any water during the test.

Goal: Verify all plumbing connections are watertight

  • Use a dry paper towel to wipe each connection; even a tiny amount of moisture will be easy to see on the paper.

FAQs

Do I need the specific Milwaukee screwdriver mentioned, or will any flathead and Phillips head screwdriver work for this project?

While the Milwaukee screwdriver is a good quality tool, any standard flathead and Phillips head screwdriver of the appropriate size will work. Ensure the screwdriver tip matches the screw head size to prevent stripping the screws during removal or installation, which is a common issue.

What should I do if I can't shut off the water supply to just the shower, or if water continues to drip after shutting it off?

If you can't isolate the shower's water supply, you'll need to turn off the main water supply to your entire house, usually found near the water meter or main shut-off valve. If water still drips after turning off the supply, double-check that the valve is fully closed. For persistent drips, you might need to address the shut-off valve itself or consult a plumber before proceeding.

My old Delta handle's screw cover is stuck or won't come off easily. How can I remove it without causing damage?

Often, old screw covers can be stiff due to mineral buildup. Try gently prying around the edges with a thin, flat tool like a plastic putty knife or the edge of a flathead screwdriver wrapped in painter's tape to avoid scratching. If it's still stuck, a small amount of penetrating lubricant applied carefully around the edge might help loosen it, but wipe away any excess immediately.

Is 45 minutes a realistic time estimate for a complete beginner, or should I budget more time for this Delta handle replacement?

The 45-minute estimate is generally realistic for someone with basic DIY skills and the right tools on hand. However, as a complete beginner, it's wise to budget an hour or two. This allows for potential issues like stuck screws, locating your main water shut-off, or needing extra time to review instructions carefully.
