Pressure Test Water Lines — Turn On Water and Check for Leaks
Part of project
How to Install an In-Line Water Filter for a Refrigerator Ice Maker · Step 6 of 7
In this video
After all water lines are run and the fixture stub-outs are capped, the final step before inspection is to test for leaks. Go to the main supply valves and slowly open them to allow water to fill and pressurize the new pipes. Once the system is under full pressure, meticulously inspect every single connection, joint, and fitting with a flashlight. Look and feel for any signs of moisture or dripping. Leave the system pressurized for an extended period to check for slow leaks.
Goal: Plumbing System Inspection
- Wipe all fittings with a dry paper towel before pressurizing. Any moisture will be much easier to spot on the dry surface.
Used in this video
- Flashlight (Tool Type: Hand Tools, Power Source: Battery) — Visually inspecting fittings and joints for moisture in dimly lit areas.
- Pressure Gauge (Tool Type: Testing equipment) · optional — Attaching to a hose bib or stub-out to verify the water pressure in the system and monitor for pressure drops, which indicate a leak.

FAQs
The project says 'beginner' and '3 hours'. Is it really that easy and quick for someone new to plumbing?
Yes, this is considered a beginner-friendly project. The 3-hour estimate accounts for gathering tools, preparing the area, and meticulously checking for leaks. Most of the hands-on work takes less than an hour, but taking your time, especially during leak detection, is crucial for success and preventing water damage.
What are the most important safety precautions I need to take, especially to avoid leaks and water damage?
Always shut off the main water supply to your refrigerator or the whole house before starting. Keep plenty of towels and a bucket handy to manage residual water and accidental spills. When tightening compression fittings, ensure they are snug but do not overtighten, as this can crack plastic lines or fittings and lead to leaks. Perform a thorough leak check for at least 30 minutes after restoring water.
Do I need all the specific tubing cutters and wrenches listed, or can I use basic tools I might already have?
A dedicated tubing cutter like the RIDGID 101 or 104 is highly recommended for clean, straight cuts on plastic or copper tubing, which are essential for leak-free connections. While an adjustable wrench is necessary, having two (one to hold the fitting, one to turn the nut) makes the job much easier and prevents twisting the water line. Avoid using utility knives for cutting if possible, as they often result in uneven cuts that can cause leaks.
Why is flushing the filter important, and how do I do it correctly during installation?
Flushing the new filter is crucial to remove any carbon dust or air from the filter cartridge before it reaches your refrigerator. After installing the filter but *before* connecting it to the fridge's water inlet, run several gallons of water through it into a bucket until the water runs completely clear. This prevents cloudy water in your dispenser and protects your ice maker from sediment.
