Viega 50143 - 1/2-Inch PureFlow Zero Lead Poly Alloy PEX Crimp Manabloc With 14 Ports - 8 Cold 6 Hot

Building my house and this is the best for my water needs being distributed without the pressure drop! Easy easy easy to install and the self printed labels for water designation are catching!

Makes running pex so easy, so and it's benefits are a great reward. Works well no leaks. Make sure u get this one it comes complete with fittings, others are 5 or 6 dollars less and dont have the connections necessary to complete the work. U will need the 3/4in fittings for inlets

Worked as expected. Thanks

Product arrived as advertised with all parts included. I Installed Manabloc with the option to supply water using top inlets only. I needed to order the supply connectors for the supply inlet on top as instructed on Manabloc advertisement. I also needed to order the bottom supply cap as my example did not require this water inlet. My installation was a little tight due to where my PEX pipes were planned to go into the Attic and also staying at least 18" away from water heater as instruction indicated. First I placed the manabloc where I planned, Second I ran each of the hot and cold lines into the attic. Then I began to make the water supply connections into the Manabloc. I then made the multiple crimp connections to connect the attic supply PEX lines into the Manabloc. Once I completed all the Attic PEX line connections into the Manabloc I opened the water supply Cold and Hot lines into the Manabloc to test for leaks. I tested at this point for all connections made just into the Manabloc before doing any further work. I heard the Water filled Manabloc and confirmed that there were no leaks. While still in the garage area where the Manabloc was installed, I finally went through the connection of each of the Attic PEX lines into the Manbloc and then I finally spent the one full day in the Attic to make the 13 PEX connections to each of the copper lines going to each of the water fixtures. My plan was to cut off the copper existing lines before they go into the wall from the attic to fixture and solder crimp connections to allow me to crimp the PEX to each of the copper fixture lines. Once completed, I opened each of the water lines from the Manabloc one at a time and verified that there was no "water leaks" to the soldered/ Crimped connections. Complete installation took 3 days from start to finish. I would recommend this product. Very happy with final results.

I have a project going where I'm remodeling my downstairs bath and laundry room. After ripping out all the sheetrock I found that the main plumbing connections were in one of the walls. "What a great idea to install one of those newfangled water pressure balancing systems!", thought I! So I researched and decided on the Viega 50143 and ALL the additional PEX piping, tooling, fittings, etc. This was a learning experience for me as I had never worked with this stuff before. Here’s what I found: The Viega was easy to install. It came with all the fittings needed, a template for drilling holes in the studs for pipe routing, labels so you don’t get lost (what’s installed and what’s not installed), and pretty thorough directions. Be gentle. It’s plastic and I could sense that it would not take much manhandling to damage it. Now that it’s in and working I found that we can take a shower upstairs and run the washer at the same time. Pure bliss. The labels are kind of cheesy and keep coming loose. Think I’ll slap a piece of packing tape over them so they quit falling off. I found that the PEX and Viega installation was just as time consuming as copper, but much more forgiving. I like it. Anyone wanna do the sheetrock for me?

You’re doing any water hook up to the house. This is a item that’s well worth having it controls each individual line by shutting off individually

I'm never buying another Viega product. The product I'm reviewing is actually a replacement for the exact same manifold that I bought months ago. I couldn't return the original one, because I bought it too long ago and the "return window" had closed. I figured it would be easy to just replace the bad one with a new version of the same one, and they are cheaper than the Apollo manifolds. The problem is that they leak everywhere. Leaks on the individual lines can mostly be fixed by replacing the O-rings, but that's not really confidence inspiring. For whatever reason (manufacturing defect?) the hot side supply line always leaks. I thought I could fix this with Rectorseal. Nope. And the problem can't just be fixed by undoing stuff and trying again. Since it's connected to Pex you need to cut tubing, cut though crimp rings, replace tubing and rings with new stuff, etc. The hot side supply line also wants to get cross-threaded. I managed to avoid this, but you really have to watch out, because once you cross-thread plastic, you're done. If the hot side supply leak happened just once, I would say oops, not sure what the problem is. When it happens twice, I'm gonna say I'm dealing with crap manufacturing. I installed this in one of my rental properties because I was trying to save a little money. Bad mistake. Spend a few more dollars and go with Apollo. I have an Apollo manifold installed now and it's working like a champ.

Awesome piece of equipment. Very easy to assemble. And connect.
