What type of valve is used for PEX?

PEX valves are highly similar to regular valves. The main difference between them is how they are connected; PEX valves can connect with PEX tubing and piping (i.e., tubing and piping made from PEX) without needing transition adapters.

What should you not do with PEX?

Disadvantages of PEX Plumbing

  1. The Material Does Not Work Outside in Freezing Temperature Climates. PEX plumbing is fine inside the walls of a home, no matter the temperatures as it can be covered with insulation. …
  2. Rodents Like the Plastic Pipes. …
  3. Some Pex Types Have Had Issues.


How do you install a PEX shower valve?

Quote from Youtube video: We need to put wood in the wall here to secure this. So the valve body secure. We need wood in the wall down here because we're gonna use the same drop here for the tub spout.

What causes PEX pipe to leak?

Extreme bends and kinks place a very high local stress on the wall of the pipe making the pipe susceptible oxidative degradation. This is especially true in southern climates where the chlorine levels run high. This PEX pipe was bent beyond its limit and developed a leak at the stress point.

Can you connect PEX directly to faucet?

Benefits of PEX Over Copper



Because it’s 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.

How do you connect PEX pipe to fixtures?

  1. Obtain a specific PEX compression fitting that will attach to your fixture. …
  2. Coat the threads of the fixture with Teflon pipe dope, then screw the nut of the compression fitting over the threads on the fixture. …
  3. Push the end of the PEX pipe through a compression nut, then push a compression ring onto the end of the pipe.

    Quote from Youtube video: Allow the joint to cure according to the solvent's instructions finish by installing your faucet or toilet connector from the stop valve to your fixture. Hand tighten the nut until snug.

    Do mice eat PEX pipe?

    The Problem



    Mice and rats will chew through anything they can, including plastic, so PEX tubing is at just as much risk as the plastic-coated wiring in a car or an HVAC unit. While all rodent damage can be expensive, if rodents chew through a home’s PEX water pipes, the result can be disastrous.

    What is the disadvantage of PEX pipe?

    The biggest disadvantage to PEX is that it is unknown how well or long it will last. While PEX piping is warrantied for up to 25 years, it is unknown what could happen to PEX piping as the years go on. Since it is so new, it is hard to know what water will do to the plastic over 30 years.

    How long will PEX 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.

    Is PEX safe for drinking water?

    There are no health risks associated with drinking water from PEX pipes. A few types of PEX-pipe may cause prolonged undesirable taste and odour if the water remains in pipes over time.

    Is it OK to insulate PEX pipe?

    Yes, insulation is an essential part of installing PEX piping, as the lack thereof could lead to unfortunate outcomes. It is more resilient against fluctuations in temperatures than other commonly used materials. It’s flexible pipes and does not act as a conductor for heat and cold as easily as metal materials do.

    Can I use PEX for shower valve?

    Use threaded PEX water line fittings for shower valves. Tighten the fittings before crimping the PEX water line. A plastic bracket forms the sharpest 90-degree angle permitted for this brand of PEX.

    Can hot and cold PEX lines touch?

    Hot and Cold Water Lines Should Never Touch



    The picture above is of PEX hot and cold water lines that have been run through the framing and are touching each other the entire way. This has passed the rough plumbing inspection and is ready for insulation and drywall.

    Can I use PEX between valve and tub spout?

    I gather that 1/2″ PEX isn’t suitable to connect a tub/shower valve to the tub spout because the internal diameter of the PEX and especially its fitting is too restrictive, which will cause the shower to dribble while using the tub spout.

    Does PEX reduce water pressure?

    It won’t affect pressure, but the volume is decreased. If you do a manabloc, it probably doesn’t matter much.

    Does PEX need expansion loops?

    PEX supply expands and contracts more than copper, so don’t stretch it tight. Let it droop a little between fasteners. On long runs, it’s a good idea to install a loop as shown to allow for contraction. Another advantage of the loop is that if you mess up and need a little extra tubing, you can steal it from the loop.

    Do 90 degree elbows affect water flow?

    The use of 90° elbows upstream of a pump inlet can distort the approach flow resulting in spatial and temporal velocity variations and swirling flow that negatively affect pump performance and increase maintenance requirements.
