1 Answer. First you need to cut the PEX tubing at the access spot. That can be done with a PEX tubing cutter. Then you acquire the correct type fitting (your size requirement may differ from picture) to rejoin the cut PEX with T fitting and a branch connection for an added PEX tubing to go off toward the ice maker.
Can you connect PEX directly to faucet?
Because its so flexible and easy to use, connecting PEX to a faucet or other valve takes less time than connecting to copper. There are far less fittings required because of its flexibility, and connecting PEX to a faucet is done with a crimper, requiring no soldering.
Can a saddle valve be used on PEX?
Most saddle valves are designed to work with standard rigid copper pipes—they are not recommended for PVC, CPVC, or PEX plastic pipe. They are also designed for water systems with a maximum pressure of no more than 125 psi.
Why is PEX not allowed?
California banned PEX because of the possibility that harmful chemicals can enter drinking water. There are no studies that indicate that you will risk your health if you drink water from PEX pipes. However, PEX has been banned and reapproved in California several times, and it is used nationwide.
Will PEX water lines freeze and break?
PEX pipe will expand if frozen and contract to its original shape when thawed. But putting frequent stress on the system weakens it, increasing chances of failure and leaks. So, to preserve the strength of your pipes, you should use the same standard insulation precautions with PEX to keep it from freezing.
Do you need a water line for an ice maker?
A water line allows you to make ice in your refrigerator. Refrigerators that feature built-in water dispensers or automatic ice makers need to be connected to a water source. Fridges without ice makers or water dispensers dont need any type of water source to function properly.
How does a saddle valve work?
Saddle valves are self-tapping devices. Once mounted on a line, with the included rubber seal in place, all that is required is to turn the valve clockwise until it pierces the water line. When the valve handle can no longer be turned, it is done tapping the pipe. Turning the handle counter-clockwise opens the valve.
How long does PEX pipe last?
Additionally, long-term testing programs on PEX have shown that it has a potential lifespan of more than 100 years. So, while copper systems may have to be re-piped every few years or decades due to corrosion and pinhole leaks, a PEX system can last 10 times longer — or more.
Which is better PEX A or B?
PEX-A is the most flexible of all PEX tubing types, has little or no coil memory and gives installer an ability to repair kinks with a heat gun. 8 times the OD for PEX-B & C) is helpful, but offers little practical advantage in most cases. PEX-B is a clear winner in terms of price vs. both other types.
Should I use PEX A or PEX B?
PEX-A is the most flexible of all PEX tubing types, has little or no coil memory and gives installer an ability to repair kinks with a heat gun. 8 times the OD for PEX-B & C) is helpful, but offers little practical advantage in most cases. PEX-B is a clear winner in terms of price vs. both other types.
Where is the saddle valve located?
It is usually located under the kitchen sink, in the basement, in a crawl space, or in the cabinet next to the refrigerator. There will be a small 1/4 inch copper line attached with a saddle valve (t-valve).
What does saddle valve look like?
A saddle valve kind of looks like a horse saddle and fits over the water pipe similar to the way a saddle fits on a horse. The saddle valve is clamped on to a water pipe. Also known as a refrigerator water shut-off valve, most saddle valves are self-piercing.
Is saddle valve open or closed?
Saddle valves are self-tapping devices. Once mounted on a line, with the included rubber seal in place, all that is required is to turn the valve clockwise until it pierces the water line. Turning the handle counter-clockwise opens the valve. These valves can be installed without shutting off the main water supply.
How do you know if a water valve is open or closed?
If the handle on top is parallel to the valve, its open. Likewise, if the handle is perpendicular to the top, the valve is closed. Common places you might find a ball valve are in irrigation and in sites where you need to control water supply from one area to another.
