How to install PEX pipes to the bathroom sink

PEX is a modern type of plastic tube used to transport drinking water in residential and commercial buildings. PEX has several advantages over traditional copper pipes: it costs less to manufacture and is easier to cut and connect. It also resists oxidation and corrosion and can carry hot or cold water for sinks, showers, toilets and many other accessories. Compression fittings make connecting a piece of PEX to a bathroom sink quick and easy.

Instructions

  1. Locate the main shutoff valve of the water line inside your house and turn clockwise to shut off the flow of water to the entire house.
  2. Look for the heel of PEX out. The auxiliary code out is usually found along the base of the floor or the back of the wall directly below the sink. The heel cape can be identified by the two protruding pieces of PEX tubing. One line is for the cold water and the other is for the hot water line. The hot water line should be marked with a color, such as red, on the side of the pipe.
  3. Place a valve on the Shark bite water pipe on each of the auxiliary code outputs. Press down on the valve so that it slides on the measuring tube as much as possible. The shark bite connection does not require any additional tools, such as installing inside the compression valve will permanently perform the tube safely.
  4. Turn the valve control knob clockwise until it is tight. This will ensure that water will not enter the lines until the installation is complete. Some valves need only a quarter turn, while others require several full rotations to close completely.
  5. Screw on braided water lines in the threaded connection at the end of each valve. Turn the nut on the water lines by hand until it is tight and then turn each complete turn with a pair of pliers.
  6. Illuminate the workspace under the sink with a lantern light or work.
  7. Pull the open ends of the water pipes to the base of the sink faucet. Place the water line that is connected to the hot water pipe, marked with red or another color, to the control valve on the left in the sink. Screw the nut on the water line into the threaded connection protruding under the left control knob. Squeeze by hand and continue with a full rotation with a pair of pliers.
  8. Place the water line that is connected to the cold water pipe to the control valve to the right in the sink. Screw the nut on the water line into the threaded connection protruding under the left control knob. Squeeze by hand and continue with a full rotation with a pair of pliers.
  9. Turn the two control buttons of the Shark Bite valves to the left to open the flow of water to the sink. Turn the main water valve to the left to start the flow of water to the house and test both key handles.
