Planning Your Pex Installation
Welcome to the exciting world of DIY plumbing, where upgrading to PEX piping for your bathroom sink marks a leap into efficiency and reliability. Planning your PEX installation is the blueprint of success. Careful preparation leads to a leak-free outcome and years of trouble-free service. Let’s roll up our sleeves and lay the groundwork for a smooth PEX pipe installation.
Measuring For Pex Piping
Before purchasing, you need to know how much PEX pipe you’ll need. Start by measuring the distance between the sink’s water valves and its connection points. Include vertical and horizontal runs. Adding a few extra feet allows for mishaps or adjustments during installation. Document each measurement.
- Measure the cold water line.
- Measure the hot water line.
- Account for pipe bends and turns.
PEX comes in various lengths. It’s sold in coils or straight sticks. Coils offer flexibility but may need straightening. Sticks are rigid but easy to measure against. Choose the one that best suits your project.
Sketching The Sink’s Pex Layout
A clear sketch prevents mistakes. Use graph paper to draw the sink, the pipes, and the connections. Mark the hot and cold water lines with different colors.
| Component | Location | PEX Size |
|---|---|---|
| Hot Water Line | Left side of the sink | 1/2 inch |
| Cold Water Line | Right side of the sink | 1/2 inch |
Include measurements and note the sizes of connectors and shut-off valves. This visual guide aids in purchasing the correct materials and serves as an installation reference.
With these steps complete, you’re set to embark on installing your PEX piping to the bathroom sink. Remember, a solid plan paves the way for a flawless installation.

Connecting Pex To The Bathroom Sink
Finalize the installation by connecting the PEX to your sink. Here’s how:
| Step | Action |
|---|---|
| 1 | Ensure the water supply is turned off. |
| 2 | Align the PEX pipe to the sink’s inlet valves. |
| 3 | Use channel-lock pliers to tighten the compression nuts. |
| 4 | Open the water supply to check for leaks. |
Ensure each connection is snug, but be careful to not over-tighten and damage the fittings.
Testing For Leaks And Functionality
After installing PEX pipe to your bathroom sink, the next crucial step is to ensure there are no leaks. This not only guarantees a clean work area but also prolongs the lifespan of your plumbing. Let’s dive in and learn how to test for leaks and functionality.
Performing A Pressure Test
To confirm the integrity of your installation, a pressure test is essential. Follow these simple steps:
- Close all valves connected to the PEX plumbing.
- Attach a pressure gauge to the system.
- Use a manual pump to raise the pressure to the recommended PSI.
- Hold the pressure and observe the gauge.
- Check for any pressure drops, which may indicate a leak.
If the pressure remains steady, your system is likely leak-free. If not, you’ll need to locate and fix any leaks before proceeding.
Final Checks Before Use
Once you’re confident the PEX pipe is sealed and pressurized, follow these final steps:
- Inspect all fittings and connections for tightness.
- Ensure there are no visible leaks around the sink and pipe ends.
- Slowly open the main valve to allow water into the system.
- Run the water and check for any signs of dripping or moisture.
Listen for unusual noises that could signal air in the pipes or faulty installation.
With these tests complete and no issues found, your bathroom sink is ready for regular use. Enjoy the fruits of your labor with peace of mind.
