- Be sure the pipe is pushed deeply into the compression seat.
- Don’t overtighten the fitting. Tighten on a half turn when you encounter resistance in turning. Then, turn on the water valve testing the connection. If the connection is sealed, the job is done. If it leaks, turn off the water, tighten the nut about a quarter turn at a time, then turn on the water to test again. Repeat this step until it’s sealed.
- Leave a few inches of pipe straight before the pipe corner or before you bend the tube.
- Clamp your pipe firmly to make sure it can’t rotate.
