Rated 5.0 out of 5.0Â by Garrett Just re-piped my whole house with PEX
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.
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.
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.
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.

Rated 5.0 out of 5.0Â by BigPapiDIY $27 of PEX + 2 Sharkbite Elbows ($17) saved me $950!
Have previous DIY experience with copper pipes, but am a PEX convert now. Needed to run a "bypass" line due to a broken hot water pipe in the concrete subfloor. Plumber quoted me $1000 to run this bypass from one bathroom, up through the attic, and down into the wall behind the Master bathroom plumbing connection. It took me 2 hours, and these $50 in parts. PEX is great!

This stuff is great. No sweating copper! Easy to work with and you can run it like Romex. Tons of fittings and much cheaper than copper.

pex tubing in general with sharkbite fittings is very easy to use, coiled pex is a mixed blessing in that it may save fittings if you have long runs but you have to wrestle it, easier if two people are working with it, otherwise, next time I'll use the 20' straight lengths and pay the extra if necessary
