## Questions & Answers

**Q: will this brand of pex burst if water is left in the line and freezes**
A: NO it will not. The fittings will crack if they freek. I work on mobile homes and we ONLY use Pex or Sharkbite Pex tube. I have seen the entire 100 feet freeze and it just swels up a tiny bit. Any fitting that freezes though will crack and burst or leak. Do all home run lines and put a heat tape on it if your woried it may get exposure to winter freezing temps. I have done over 60 homes with this and always get this question.

**Q: Is this PEX-a**
A: This is not PEX-A (more often referred to as AquaPEX). This is PEX-B, the most common variation of the three types available. AquaPEX has some benefits, such as less coil memory so that it is easier to work with as well as more resistance to bursting if water freezes in the tubing. It is not better quality, it is just manufactured differently and the letter signifies what method of installation can be used.
You only need to use AquaPEX if you are using the expansion method which requires the PEX to expand to accept the fittings. It then resumes its shape around the fitting with the help of special expansion sleeves. With PEX-B, the crimp method is used. You could use AquaPEX with the crimp method, but you could not use PEX-B with the expansion method since it is not designed to expand to the tolerances necessary. AquaPEX is also 40% more expensive and not readily available everywhere. You generally need to buy this type at a plumbing supply house.

**Q: Does this tubbing works with pex expansion tool?**
A: NO that tool can only be used on pex - A

**Q: What is the i.d. of this tube?**
A: The diagram clearly shows that this tubing is 1/2 in. O.D. and is mated to the Sharkbite  1/2 inch ball valve. Why do you state that it's 1/2 in. I.D.?

### ⭐⭐⭐⭐⭐ Quality stuff
*by S***F on April 11, 2025*

Worked well and good price!

### ⭐⭐⭐⭐⭐ JUST RE-PIPED MY WHOLE HOUSE WITH PEX
*by G***T on March 19, 2014*

Back story: I discovered I had a slab leak on my hot water line under my bathroom and upon further investigation discovered a cold water leak under my entryway. Being in Ventura County, CA our water is hard and my tract home was made cheap. It was built 30 years ago with copper in the slab foundation. The plastic sheathing they used to isolate the copper from the concrete was super thin and subsequently eroded as the pipes expanded and contracted with temperature. This lead to major corrosion of the copper (especially in the hot water line) from the outside and the predominance of minerals in our hot water corroded the insides of the copper. I knew this would be a problem when I bought the house, as I have lived in the neighborhood for a while. Many neighbors have all had similar issues and paid big money to patch or re-pipe.My background: I am an avid DIY-er with just about every type of project. Electrical, plumbing, heating/AC, appliances, etc. I have patched and repaired many types of plumbing including copper, galvie, ABS, and PVC. I was new to PEX. What I did: I did a lot of research before making the purchase and weighed all of my options. I considered paying a plumber, doing it myself, using copper, and using PEX. I decided on PEX and wanted to do a manifold system so I can easily remodel my bathrooms in the future without turning off the whole house water supply. My house is a 1550sqft single-story house with 2 full bathrooms. I opted to replace the 1" copper line where it comes in to the garage from the shut-off valve outside and run it to the manifold location near the water heater. I split the 1" copper with a "T" and reduced it to 3/4" copper to the water heater supply and the cold-water side of the manifold. I used 3/4" SharkBite PEX stubs to feed into the manifold for a little flexibility. I ran 1/2" PEX to each fixture. I used red PEX for hot and blue PEX for cold. I wanted to reduce the amount of fitting and connectors in the system, but used 1/2" PEX to used copper stub-outs with new compression fitting valves to lead to each fixture; I didn't like the idea of the PEX sticking out of the walls. I used the stainless cinch-ring clips because the crimper is a bit smaller and fits in tighter spaces. I opted for the 100' rolls of the PEX so I could have a direct shot to each fixture without any unions along the way.The Review: PEX, though flexible, is still fairly rigid and a bit tough to uncoil, but much better than copper. With a little patience and coercion, I was able to thread it through the headers and down the walls with minimal drywall cutting. I used 90-degree angle guides to protect the bends. Using the cinch rings at the connection points was easy. It took me 53 hours of work over the span of 4 days to complete the project (drywall repair included). It would have been a bit faster, but I had to cut a hole in part of my roof to access a header above the kitchen sink.Bottom Line: I am beyond thrilled with this product and how easy it was to install. I was able to re-pipe my entire house by myself in a few days for less than $1000. The copper portion alone cost me $300, so that puts the PEX at $700.
