Should I replace galvanized with PEX?

Yes. If you have galvanized pipes in your hope, you should replace them with PEX. PEX piping is made of Polyethylene (PE) that is cross-linked (X). It is flexible, durable, and high-density.

Can PEX be used with galvanized pipe?





Install a threaded transition fitting to go from galvanized pipe/fitting to PEX tubing. Depending on the type of PEX fittings used, a dielectric union might be needed. Connect the PEX tubing to the fitting using a compatible method. Check connection for accuracy.

How do I convert galvanized pipe to PEX?

Quote from the video:
Quote from Youtube video: And you push that on there like that you put your crimp thing on and your crimp it on there. And then you run it to your fixture. And that's pretty much that.

What size PEX tubing should I use?

In general, the greater the distance from the manifold to the fixture, the wider the PEX tubing should be. 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.

What should I replace my galvanized pipes with?

The 3 common types of pipes used to replace galvanized are PEX (Cross-linked polyethylene), PVC-CPVC (polyvinyl chloride or chlorinated polyvinyl chloride) or copper pipes. Each pipe type has its own set of pros and cons.

How much does it cost to replace galvanized pipes with PEX?





The cost to replace galvanized pipes is from $2,000 to $15,000 depending on if you use PEX, copper, or another material. Replacing galvanized pipes in older homes is important because of the way galvanized pipes tend to degrade over the years.

How do you connect PEX pipe to galvanized pipe without threads?

Use a stainless steel coupling if the galvanized pipe is in a damp position to avoid problems associated with rust. Unthreaded galvanized pipe connects together using a coupling. Connecting together galvanized pipes that are non-threaded uses a coupling that creates a sealed joint.

Do they make SharkBite fittings for galvanized pipe?

The actual SharkBite push to connect fittings are not designed to press onto galvanized pipe. For mating your PEX to galvanized, SharkBite makes a threaded to press fit transition adapter. You will need to square cut the end of your galvanized pipe and then rethread it.

How do you connect the non threaded galvanized pipe to PEX?

Insert one end of the unthreaded galvanized pipe into the fitting. Align the coupling end with the drawn line on the pipe. Insert the second pipe into the coupling and place the coupling centered between the two drawn lines.

Can I use blue PEX for hot water?



Color-Coded: Red PEX pipes can be used for hot water supply lines, blue PEX for cold water supply, and white for either hot or cold.

What is wrong with PEX plumbing?

PEX piping has a maximum bend radius, which can lead to stress on the pipe caused by improper installation. In addition, extreme bends and kinks place a very high local stress on the wall of the pipe, making it more susceptible to oxidative degradation.

How do I choose PEX pipe?

Types of PEX

  1. PEX-A, which has the most flexible tubing and best freeze- and kink resistance, is ideal for use with kitchen and bath fixtures.
  2. PEX-B is slightly less flexible and less freeze-resistant.


What is the difference between red white and blue PEX tubing?

Red PEX pipe carries hot water. Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water. Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).

What is the difference between Type A PEX and Type B PEX?

Flexibility – PEX-A is the most flexible, allowing for it to be fastened by cold expansion, which allows the end to be fluted prior to inserting the fitting. PEX B is not expandable and you should never expand the end of a PEX-B pipe. Kink-Resistance – PEX-A has the greatest resistance, PEX-B the lowest.

Where is PEX not allowed?

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.

When should you not use PEX pipe?

PEX plumbing is fine inside the walls of a home, no matter the temperatures as it can be covered with insulation. However, one of the disadvantages of PEX plumbing is it cannot be used outdoors in cold climates as there is no way to cover them and protect them from freezing temperatures.

What is the lifespan of PEX plumbing?

30 to 50 years

While you can expect PEX to last for 30 to 50 years, copper piping will outdo it by about two decades, with a typical lifespan of 50 to 70 years. Copper is a more durable option that isn’t susceptible to rodents or sunlight. These pipes can easily handle water pressure of up to 1,000 psi.

Do mice eat 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. If you’re hearing rustling noises coming from the attic, it’s time to do an inspection.

How do I stop mice from eating my PEX?

Mice and rats can squeeze through unbelievably small gaps to enter a home, so the first step is to inspect the home’s outside perimeter and seal all holes and gaps around vent pipes with a rodent-proof sealant, such as Tomcat Rodent Block (available from Amazon).

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.
