Looked around for a good manifold system and this one impressed me for the most part, but the negative about this product is in the valves. I purchased the 18 port compression version with 1/2" ports, but was very disappointed in the valve port itself, which is only a 5/16" of an inch opening. Viega did not do anybody justice for using 1/2" PEX ports on this system when you are restricting the flow at the port with an opening of 5/16", the 3/8" version Manabloc probably would have had the same flow. Viega needs to redesign this unit with FULL PORT vales to give the customer 1/2" flow. Realizing that 1/2" PEX tubing is still only 3/8" ID, but at least you would have a full flow through the tubing and not a restriction at the valve. BAD design on Viega's part. Hope this helps others looking at flow through rates, pressure, etc.

Comments about 1/2", 24 Port Compression MANABLOC (9 hot, 15 cold):
Renovating a home and decided to use the home run system - running individual lines is fast.I ordered this product mid afternoon one day and recieved it next day with no shipping costs. Less expensive than my local plumbing supply house. Carefully packaged and nothing missing.
Bottom Line Yes, I would recommend this to a friend

Comments about 1/2", 18 Port Compression MANABLOC (8 hot, 10 cold):
This manifold system is easy to install. Well built solid design. Direction on tightening the compression nut say tighten until you can see the white sleeve and don't over tighten. You need to send about a 1/16 of the white sleeve before it is completely tight. Other than that great product

i liked everything about the manabloc,it is very easy to install,i put it in my rental house,and in fact it is so good,i am now going to put one in my own house,no more bad pipes in our home,all clean,and nice with better water flow.
Super easy install
By Pastor Paul
from Bucklin, KS
This manifold is easy to install and equally as easy to connect the pex tubing. This is a great way to install water lines throughout the house. I used it in an existing house and retrofitted all the existing fixtures as well as adding new fixtures. I'm sure it is even easier in new construction. Great product.

This is the second one of these that I have Installed.Quality ProductMade in the USA
buy the wrench
from harryville, ny
Couldnt imagine trying to install the manabloc without the wrench they offer and having seen the video on installation. That said, it was beyond easy to install. Super product. I am a home owner building from scratch, and this is the way to go. I ran the lines in the whole house and attached it all to this manabloc faster than I figured possible. Must be great for contractors
quick and easy
By DIY John
This Manabloc made the transition from coper to pex so easy I completed my whole house in 3 day basically by myself with 3 bathrooms on two floors. don't forget the MANABLOC Wrench For Compression Lock-in Nuts made hook up even easier.
Great product, easy to use and install
from Chicago, IL
The product was very easy to install and connect to. It has all of the hardware needed for a surface mounted installation, which is not clear in the product description. I would recommend picking up the $15 wrench, as it was very difficult for me to tighten the nuts without it, and I caused a lot of surface damage to the nuts when tightening with a Cresent wrench.
Only available in SupplyHousr.
Comments about 1/2" / 3/8" 24 Port Combination MANABLOC:
Received ontime .Great service and products. I would recommend it to anyone .
Made replumbing our cabin quick (and easier)
By Darwin's Anvil
I needed to replace the plumbing in our cabin (5 bed, 3 bath) and the MANABLOC reduced the installation time. It allowed me to move the water supply to a convenient central distribution point and dramatically reduce the wait time for hot water to reach more distant fixtures. One thing to be mindful of if you are using the MANABLOC compression fittings is to not overtighten the fittings. If you are really cranking down on them, the plastic body of the MANABLOC can twist. That said, when I did it, I just got a squirt out of the fitting I was tightening; when I released it, it was undamaged and water tight.
