Good price

This tubing was purchased as a part of the new kitchen installation in our antique farm house. The new kitchen was being installed in the large room at the rear of the house and getting water to that point from where the town water comes into the small basement in the front is difficult because most of the house is over an unheated crawl space. The solution was to run a completely new water line inside the house from the front all the way to the rear along the baseboard on the second floor. I bought a coil of this Sharkbite tubing for that early in the project. This 1/2" tubing was to connect the end of that coil, and the water heater I installed in the second floor utility room, down to the kitchen. Once that project was complete, I turned the old kitchen into a laundry room, so more of this 1/2" Sharkbite was needed for that, plus some re-plumbing in the basement: the old-timers who plumbed this house sixty years ago surely loved to sweat little pieces of copper! The Sharkbite is perfect for simple residential installation. The fittings themselves are pretty expensive, but the time saved in putting plumbing together and the simplicty of being a plumber using SharkBite tubing cannot be exaggerated. The price was the same as at the big box, but I saved myself the 50 mile round trip by ordering through Amazon.

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.

It was quite hard to make the tube straight. The quality of the tube is great. I have not seen any leak in the last few years after installation.

Perfect if you need lines buy it online. I use this for my outside boiler. Yes, pex lines can hold a lot of pressure and a lot of heat I couldn’t afford $1000 100 foot for boiler insulated underground lines so I made mine but that will work just fine for anything and it’s a lot cheaper than in stores.

Worked as intended.

Worked as needed

Has done its job well, so far, for plumbing in an off-grid application

Easy to install Did not have any trouble during installation The main thing that we didn't have any leaks Highly recommend to everyone
