Can you use PEX for drain?





As with PVC, PEX is rust-proof, infinitely durable and marked with identifiers along the exteriors of pipes. PEX’s purpose, however, is the opposite of PVC — whereas the latter is restricted to drain lines, the former is only used for incoming water lines.

How do you winterize PEX?

Ways to Keep PEX Pipe from Freezing

  1. Keep the room temperature above 55 F.
  2. Add insulation to particularly cold places such as attics, garages and basements.
  3. Drip faucets to keep water moving in the pipes.
  4. Shut off the water to outside hose bibbs (spigots) & drain the pipes.
  5. Install frost-free sillcocks.

How far can you run half inch PEX?

A 3/8-inch line is sufficient for lengths up to 250 feet; 1/2-inch line will deliver adequate water pressure up to 350 feet; and 3/4-inch tubing is necessary to run a 500-foot line. Look for a maximum recommended lengths specification on the PEX packaging.

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.

Where should you not use PEX?





PEX can’t be installed in high heat areas.



You can’t install PEX in high heat areas like near recessed lighting. This also means you can’t connect PEX directly to a hot water heater, but you can use a connecting material to do this.

Is there a flexible drain pipe?

The Flexible Drain Pipe system is a revolutionary landscape drainage system for residential and commercial use and the newest brand of product for Rain Bird. This unique pipe expands and flexes, making it perfect for tight spaces and curvy places.

Why can’t you use PEX for tub spout drop?

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.

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.

Do PEX elbows reduce flow?



At a rate of 8 feet per second, the CPVC fitting will cause less than 1% restriction in flow while PEX fittings create a 23% to 54% reduction in flow, depending on the fitting used.

Do you have to use a manifold with PEX?

Do I Have to Use Manifolds with PEX? No. You can install PEX fittings supply just like you would other pipe, with main lines and branches to each fixture. But you lose a lot of the benefits of PEX with this system since it requires so many fittings.

What size PEX for a bathroom?

It’s a common question regarding bathroom installations. What size PEX for the bathroom to use? Usually, ½ and ¾ of inch PEX pipes are used in your bathrooms.

Can you plumb a shower with PEX?



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 I run 3 4 PEX to shower?

Some shower arrangements require high flow and so a 3/4″ cold line all the way to the shower valve might be future proofing even if you don’t need it now. Personally I use a low flow head and consider a rain head and side jets an outrage, but some want that.

Is PEX better than copper?

PEX doesn’t degrade like copper, higher PSI rating freezing pipes will still burst, but PEX will be able to handle more freezing water than copper. PEX Tubing is much more resistant to freeze-breakage than copper or rigid plastic pipe. PEX Tubing is cheaper because it takes much less labor to install.

Can mice chew through PEX pipe?

PEX Pipe Is Vulnerable



Rodents Chewing Through PEX Pipe is a common problem in our area. It doesn’t matter how old your home is, if you have an attic, you need to watch for rodent damage to PEX Pipe or PVC.

What is the life expectancy of PEX plumbing?



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.

Will PEX pipe freeze and burst?

PEX pipes, just like any pipe, can freeze when the temperature drops too low. Because the pipes are designed to be flexible, PEX has the ability to expand. Although it is still possible for them to burst, this means PEX pipes are less likely to rupture after freezing.

At what temperature does PEX pipe burst?

Don’t place the blow dryer directly on the pipe, hold it a few inches away and test the pipe with your hands to feel if it’s thawed enough. But be aware that the general rule of thumb is that pex tubing can withstand temperatures of up to 200 degrees Fahrenheit.

Should you insulate PEX piping?

You should insulate PEX pipes because they can freeze and potentially burst when temperatures drop below 20 degrees Fahrenheit. This is particularly important in cold regions, crawl spaces, attics, or other cold places. Doing so can also improve energy efficiency and reduce moisture and condensation.
