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.

Great Replacement F/12-Port Version
By RV Service Center
from Central Maryland
Comments about 3/8", 14 Port Compression MANABLOC (6 hot, 8 cold), Zero Lead:
No one could find the old 12-port version so we had to assume it must be discontinued. This worked great as a replacement for our RV application, we just had to cap the large top inlet. Also FYI to all; the 3/8" in the description is for the water line size NOT the male thread size on the port fittings! The thread sizes are 1/4" larger than stated water line size. In this case the MPT fittings are 1/2". Also, it IS possible to swap the red and blue valves if you are very careful doing so. Great product though.
Bottom Line Yes, I would recommend this to a friend

Easy to install. Compression fittings are very easy and reliable. I just used pex in an older building for the first time. Installation went very fast.
Making my life easier one port at a time

Comments about 1/2", 24 Port Compression MANABLOC (9 hot, 15 cold):
I bought this as a first step in a much larger project to re work all the old plumbing in the house. The block allows me to work each room into the new system.I am also enjoying the balanced water pressure as a result.Overall great product and I would definitely recommend it.

Comments about 1/2", 14 Port Compression MANABLOC (6 hot, 8 cold):
Great product. My only issue was not getting three Manablock intake fittings, it only comes with two. And not getting the wrench to tighten the port fittings on the manifold. It's 15$ to buy it separately. I think it should come with the kit. Other than that...it's good stuff.
ManaBloc Manifold Swap
By JC from CS
from Colorado Springs, CO
Comments about 1/2"" / 3/8"" 30 Port Combination MANABLOC:
I had to replace an existing Manabloc Manifold. It was an easy straightforward operation. Remember to label the lines before disconnecting.I only wish that the whole manifold didnt need to be replaced due to crack in one valve. Seems like a waste of plastic if nothing else.
I would buy this again!
By Non Professional
from Elkhart IN.
This manifold set up is the only way to go when installing a complete system, The compression connections are the best and leak free. I would use this product again. While the available wrench is not necessary It sure made the hook up a lot quicker.
Love this product
from Perrysburg Ohio
This makes installation so easy. Main line in the bottom, hot water heater in and out the top, buy as big a bloc as you need for your house.
Comments about 1/2", 36 Port Compression MANABLOC (14 hot, 22 cold):
