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.

Review of Viega ½", 24 Port Compression
from Hudson, OH
Comments about 1/2", 24 Port Compression MANABLOC (9 hot, 15 cold):
I purchased the 24-port Viega compression fitting manifold to replace a 24-port Vanguard Manabloc unit in my home. The original construction (built in 1997) used a combination of PB & PEX pipe (I have no idea what possessed the builder to mix piping materials - perhaps that is what his sub had available). The original manifold had developed a leak in one of the block sections. I suspect root cause was O-ring failure. Viega customer service guidance is that Manabloc O-rings are not replaceable as the manifold is assembled & pressure tested prior to shipment. The entire modular stack is pre-tensioned at the factory, thereby compressing the O-rings to the designed level of squeeze.As other reviews have noted, the old Vanguard manifold had a gap where the hot/cold block-off plate was located. Depending upon the amount of slack available in the original piping installation, this could pose a problem in making port connections. I was fortunate in that Viega's design and tooling carried over from the Vanguard Manabloc design – this was critical in making the port connections, as I utilized all Vanguard port connection fittings to the new Viega manifold.Making manifold connections with the compression fittings is best done using the unique Manabloc wrench (purchased separately). Given the tight center-to-center distance between ports, I highly recommend purchasing this special wrench, as it cuts hours off the job and enables proper torque for leak-free connections. Pressure testing following port connection confirmed all connections were leak-free.Water supply connection to the manifold was made with Viega compression connections and ¾" Rifeng PEX crimp rings using a Watts crimp-all tool (purchased separately from SupplyHouse). The Watts crimp tool provided secure crimps the first time without issue.My compliments to the entire team at SupplyHouse – customer service was nothing short of world-class, as they promptly and efficiently handled the numerous questions I had regarding manifold replacement, mating old compression fittings with the new manifold, dimensions of the replacement unit, etc. Also, the online videos they make available through their website are very informative and empowering.As a DIY endeavor, I found this to be a challenging project requiring a significant investment in time to research replacement parts & installation technique which ultimately produced a satisfactory result at a reasonable cost. Although I have an engineering background, I am not sure I would have tackled this project without the knowledge (and confidence) provided by the videos, manufacturer's installation manual and other documentation SupplyHouse makes available online. I would not hesitate to tackle another plumbing project with the SupplyHouse team of professionals by my side.

Not quite the perfect replacement

Comments about 1/2" / 3/8" 30 Port Combination MANABLOC:
I purchased this to replace a previous manabloc that had developed a leak. unfortunately not all the sizes of the ports matched the previous installation (some were 3/8" where previously were 1/2"). It required getting some adapters. This was due to the contractor installation of the previous manafold rather than the manufacturer. It did however necessatate a delay in installing doing to having trouble finding adapters.
