PEX Installation Methods

PEX can be installed in the branch and trunk, sub manifold, or manifold method. What does that mean? What are the pro and cons? Find out in this training clip on pex install methods.

I wish my plumbing looked that good. Mine looks like a firecracker went off in a bowl of spaghetti. When I found the empty Crown bottle under the garage floor, it all became clear.

Best video on the PEX systems. And they do make Manifolds with shut off valves too. Used these in my own home with PEX A, and I drain my outside spigots every winter just because I remember frozen water lines as a kid. And extra upside is if you go on vacation or leave your home for an extended period of time, it is easy to shut the water off to everything in your home so you don't come home to a flood. To me the piece of mind is worth an extra 200-300 bucks in hardware.

I learn more useful info on YouTube than I ever did in school. Truth.

Perfect video. That seriousness on your face at the end of your video, it brings out the the profesionalism in you. Thank you.

This guy knows what he's talking about. So, watch and listen carefully. I have been doubtful about DIYing this kind of plumbing. I have watched a few similar PEX installation videos on YouTube University but this particular video sums it all up for me. I feel more confident this morning and I took lots of notes and I'm charging ahead with my big project. I have already ordered the Manabloc manifold and the PEX-B tubings. I hope to share the good news about my project when done. Thanks a lot for sharing this knowledge via a lecture-style training video, sir.

Nice job. Looks organized and neat. I will say one thing that I have had troubles with are the brackets that bend the pex to a 90 degree. In hot and arid climates like I am in with the Phoenix area, over time the bends tend to crack on the outside bend. Thanks for taking the time to put this mockup together and the explanation of the different types of systems.

Wow! Great video dude. Very clear, thorough and informative. You're showing us and not just telling us. All new home buyers should see this.

Great video! Looking at redoing an old house and going all PEX A. These new distribution manifolds with individual shutoffs look really nice :)

[five-forty]

Excellent explanation of the differences between each system. Thank you!

[hshcjekxh]

Never thought about using the white stub outs, great idea!

[titusdaniel]

I almost didn't watch because I'm spoiled by the higher production values on youtube these days, but the video was really great. Thanks for sharing the information.

Great video and thank you for explaining the differences between the fittings manifolds and PEX types. Really appreciate you making this.

[texasrox]

this is the exact intro to PEX that I needed

You guys using Type B&C PEX need to understand how restrictive it is, especially 1/2". The inserts go inside the 1/2" ID AquaPEX where the fitting are all full flow 1/2", for example. So in sizing your runs, you'll need to go to the next size pipe in order to account for the friction/restriction loss of the Type B&C PEX insert fittings. I've seen houses with less flow than the copper they had after they re-piped with Type B&C PEX, because they didn't take into account the restrictions from the insert fittings.

Trying to learn about the Pex Systems for a small home im building... this just helping me understand way more about the layout Thanks for sharing !

[StanStone]

Pretty sure this guy has been around the block a few times.... Thank you sir... that was very informative...

[jandshatton]

Have to say, for a plumber double white is okay but for homeowners they never can figure out which side is hot and they screw up when they install new faucets and tub cartridges and what not. Color coding just helps people know what they are hooking up. Agree white looks better though

[shadowfox_]

Thank you for the lesson! I really need to change out my galvanize pipes and was thinking of going with CPVC, now I'm going to go with PEX-A if I can find it, the local Menards and lowes seem to only carry PEX-B.

If someone were to plumb 3/4 to 3/4 on the trunk and branch would they likely have pressure issues? I'm plumbing a small cabin and everything is within 20ft of the pressure tank and I figured it would be fine...

[jimyeats]

I think the best compromise is a modified manifold system that combines a small manifold with smaller trunk and branch sections. Less fittings, less piping, still easy to isolate and fix if there are any issues.
