How to Install a New Dishwasher · Step 8 of 9

With all connections made, slowly turn the water back on at both the hot and cold shut-off valves. Turn on the faucet and let the water run for a minute. As the water runs, thoroughly inspect all the new connections underneath the sink—including the supply lines at the valves and the faucet, and the entire drain and P-trap assembly—for any signs of leaks or drips. If any leaks are found, turn off the water and tighten the leaking connection.
Goal: Ensure the installation is watertight
- Turn the water on slowly to avoid a sudden surge of pressure that could stress the new connections.

FAQs
What are the most critical safety steps to take before starting to disconnect the old dishwasher?
Always turn off the water supply valve leading to the dishwasher and cut power at the circuit breaker first. This prevents potential leaks, electrical shocks, and damage while working with water lines and electrical connections.
What are the most common causes of leaks when connecting the hot water supply line and drain hose, and how can I prevent them?
Leaks often stem from improperly tightened connections or insufficient Teflon tape on threaded fittings. Ensure fittings are hand-tightened, then turn an additional 1/2 to 1 full turn with a wrench, and apply Teflon tape only to male threaded connections to create a watertight seal.
The project is listed as 'beginner' with an estimated 5 hours; is this realistic for someone with no plumbing experience, and what factors might extend the timeline?
While beginner-friendly, 5 hours is an estimate for straightforward installations. If you encounter seized fittings, rusted pipes, or need to adjust cabinetry, it could take longer. Having all tools and materials ready beforehand will help keep you on track.
Besides the listed tools, what other items should a beginner have on hand in case of unexpected issues during removal or installation?
A small shop-vac for unexpected spills is invaluable. Additionally, having a utility knife to cut the drain hose to length and possibly a basin wrench if the old water supply connection is in a very tight spot could save you a trip to the hardware store.
