What You'll Learn
Planning the installation path
Identify the Water Source and Path:
Start by locating the nearest cold water source, which is typically a pipe or a water supply line. Decide on the path the water line will take from the source to the refrigerator or desired appliance. Consider the shortest route possible, ensuring it doesn't interfere with any wiring, plumbing, or other obstacles.
Measure and Allow for Extra Length:
Measure the length of tubing required for the planned path, taking into account any corners, bends, or obstacles. Always add an extra 2 to 2.5 meters of tubing to your measured length. This additional length provides slack, allowing for future adjustments and making it easier to maintain the line.
Mark and Drill Holes:
Along the planned path, mark the locations where you need to drill holes. This may include drilling through cabinets, walls, or flooring to accommodate the tubing. Ensure that you do not drill through any existing wiring, pipes, or vents. If you encounter any obstructions, you may need to re-route the path.
Choose the Right Materials:
Select the appropriate tubing material, such as flexible PEX or PVC plastic pipes, which are easy to work with and suitable for water lines. Consider the durability, ease of installation, and cost of the materials. Additionally, choose the right fittings, such as push-on or clamp fittings, ensuring they are compatible with the tubing material.
Check Local Codes and Pressure:
Before starting the installation, familiarize yourself with the building codes in your area to ensure compliance with pipe sizes and materials. Additionally, check the water pressure in your area with your water supplier. If the pressure exceeds 80 pounds, you may need to install a pressure-reducing valve to regulate it.
By carefully planning the installation path, you can ensure a smooth and efficient process when adding a plastic water line. Remember to consider the shortest route, allow for extra tubing length, and choose the right materials for a successful and leak-free installation.

Disconnecting the sink water supply line
Locate the Water Supply Pipes and Shut-Off Valves:
Start by finding the water supply pipes for your sink. Typically, there are two pipes, one for hot water and one for cold water, located inside the sink cabinet directly below the faucet. These pipes will have shut-off valves that control the water flow to the faucet.
Turn Off the Water Supply:
Before proceeding, ensure you turn off the water supply by closing the valves. Rotate the valves to the right until they can't be turned further. This step is crucial to prevent water from flowing out when you disconnect the supply lines.
Drain the Water from Supply Lines:
Even after shutting off the valves, there may still be some water in the supply lines. To drain this water, turn on both the hot and cold-water faucets. You can also open any other faucets, tubs, or showers in your house to ensure the water lines are completely emptied.
Disconnect the Supply Lines:
Now, locate the connector at the end of each water supply pipe. These connectors can be made of metal or plastic. Using a wrench or a pair of pliers, unscrew the connectors by turning them to the left. You may need to use some force and turn the connectors multiple times to loosen them completely. Repeat this step for both the hot and cold-water supply lines.
Remove the Faucet:
After disconnecting the supply lines, you can proceed to remove the faucet from the sink top. Use a wrench to unscrew the mounting nuts holding the faucet in place. Once the nuts are removed, carefully lift the faucet out of its mounting hole.
Additional Considerations:
It is always a good idea to have a bucket or a large pan placed under the supply lines and the faucet to catch any water that may spill during the disconnection process. Additionally, if your sink has a garbage disposer, you will need to disconnect it separately. Turn off the electrical power to the disposer and disconnect the drain line at the bottom.

Attaching the tee fitting
First, you need to gain access to the pipe you want to connect to. This may involve some digging to expose the pipe. The depth and extent of the digging will depend on the pipe's location and the specific requirements of your project. Ensure you have carefully planned this step to avoid any unnecessary work or damage to existing structures.
Next, you will need to cut the pipe to make room for the tee fitting. Determine how much pipe you need to cut out by measuring the length of the tee fitting. Make sure to cut out enough pipe to allow the tee to be inserted comfortably. It is better to cut out slightly more pipe than necessary to ensure a proper fit.
After cutting the pipe, it's time to prepare the tee fitting for attachment. Clean the surfaces of the tee fitting and the pipe where the glue will be applied. This step is crucial to ensure a strong bond between the fitting and the pipe. You can use a suitable solvent or cleaner to prepare the surfaces.
Now, apply a suitable primer to the surfaces of the tee fitting and the pipe. Follow the manufacturer's instructions for proper application. The primer will help the glue adhere better and create a stronger joint.
Once the primer is dry, apply a strong PVC glue to both the tee fitting and the pipe. Work quickly, as the glue may set fast. Carefully insert the tee fitting into the pipe, ensuring it is aligned correctly. You may need to rotate the tee fitting slightly in a clockwise motion to secure it in place.
Finally, allow the glue to dry completely. Do not disturb or put any weight on the joint until the glue has fully cured. Refer to the manufacturer's instructions for the recommended drying time. Once the glue has set, your tee fitting should be securely attached to the plastic water line.
Remember to wear appropriate protective gear, such as gloves and eye protection, when working with solvents, primers, and glues. Additionally, ensure you are working in a well-ventilated area to avoid inhaling fumes.

Connecting the water line to the tee fitting
First, ensure you have the correct tee fitting for your project. The tee fitting should fit the threads of your valve, and the third outlet should have an outside diameter of 1/4-inch to accommodate the refrigerator water line. You can use a wrench or pliers to attach the tee fitting to the shut-off valve. Tighten the fitting by hand, then secure it with pliers.
Next, connect the sink water supply line to the tee fitting. This will involve cutting the pipe to the correct length and ensuring that the pipe ends are cut straight. If you are using a compression coupling, slip on the retainer nut and ferrule, and then tighten everything together. It is important to use a plastic ferrule with plastic pipe to prevent leaks. You may need to heat the pipe in hot water to get a tight fit.
Finally, connect the refrigerator water line to the third outlet of the tee fitting. Be sure to check for leaks at all connection points and tighten the connections as needed. Do not over-tighten the connections, as this can cause damage. Once you have confirmed that there are no leaks, you can push the refrigerator back into place and reconnect its power supply.
It is important to consult your refrigerator's manual for specific instructions and to ensure that your plumbing installation complies with the International Plumbing Code and any relevant local codes and ordinances.

Checking for leaks
Locate the Water Meter:
The water meter is a crucial tool for detecting leaks. Start by locating your water meter, which is typically found outside the house. If you're unsure of its location, contact your water utility company for assistance.
Turn Off All Water Sources:
Before checking the water meter, ensure that all water sources in and around your home are turned off. This includes indoor faucets, outdoor spigots, and any appliances that use water, such as the dishwasher and washing machine.
Observe the Water Meter:
Once everything is turned off, carefully observe the water meter. Look for any movement in the leak indicator, which could be a small triangular dial or a small silver wheel that rotates when water is flowing. If the dial is moving, it indicates water flow and a possible leak.
Take Meter Readings:
Take a note of the initial meter reading. Wait for at least one to two hours without using any water, and then take another reading. If there is a change in the readings, it suggests a leak. The larger the change, the faster the leak.
Check for Wet Spots and Water Puddles:
Inspect the areas around your water pipes and plumbing fixtures for any signs of wet spots or water puddles. This includes checking both indoor and outdoor areas, as leaks can occur in either location.
Listen for Running Water:
Pay attention to any unusual sounds of running water within the walls or floors. Water leaks can sometimes be heard, and this could indicate a hidden leak.
Inspect Appliances and Plumbing Fixtures:
Regularly check your appliances and plumbing fixtures for signs of leaks. Look for foul smells or mould/discolouration around sinks, cabinets, water pumps, heaters, washing machine valves, and hoses. Don't forget to inspect the water connections and drains of appliances like the washing machine and dishwasher.
Test Toilets for Leaks:
Toilets can be significant sources of water waste. To check for leaks, add a few drops of food colouring to the toilet tank and wait for about 10 minutes. If the coloured water appears in the bowl without flushing, your toilet has a leak.
Compare Water Bills:
Keep an eye on your water bills. If you notice a sudden increase in water usage or a consistent rise in your bills without a change in your water usage habits, it could indicate a leak. Compare bills from previous months to establish if there's a continuous increase.
Call a Professional:
If you suspect a leak or are unable to locate the source, it's best to contact a professional plumber for assistance. They have the expertise and equipment to detect and repair leaks promptly, preventing further damage and saving you money in the long run.
Remember, early detection of leaks is essential to prevent water wastage and potential damage to your home. Stay vigilant and don't hesitate to seek professional help when needed.
