Great Product
Great product, easy to work with and great instructions. Does a good job of equalizing pressure/flow for individual fixtures (my house was run is series before) and it looks cool if you're neat about it.

Smart Design with some Negatives
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.

Flood of 2018
My original 30 Port Compression Manabloc was leaking like the Titanic and I contacted a plumper but cost was too high and time was too long (2 weeks out). I needed help now, so I got on-line and reached SupplyHouse and within 5 business days I had my replacement 30 Port Compression Manabloc kit. I contact SupplyHouse and they assured me that I ordered the right kit. I installed it myself (easy with the help of SupplyHouse). The only issue I had was that I had ordered duplicate parts and when I returned them (which by the way was also an easy process), I was not credited the amount I paid. a small deduction was applied and I don't know why (Perhaps a re-storing charge of some kind). Other than that little hiccup, the overall experience was great!

Easier to install then thought
Had to replace my 13 year old 32port Manabloc which developed a crack. Replacement took almost a day. Make sure you purchase the custom wrench. I'm not a plumber and was surprised by it's ease to install.

Cannot be repaired
Initially I loved this product. Assembly went very easy. I recently went to add a new line to the system. When I did the compression fitting cross threaded. Trying to back it off the block for this valve broke. Here is where the problem is. You cannot repair the manifold. It's pressed together. No blocks are available locally or through the manufacturer. Bottom line you are left without water and need a new manifold.

Q: If using an electric tankless water heater, can the heater be fed by a 1/2" PEX line off a manifold outlet?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffNo, you will probably not get enough flow through a 1/2" line to feed the heater.

Q: I want to replace the manabloc system in my condo. The inlets that come into the Manabloc range between 1/2 and 3/8 in cold or hot. Is this the right size manabloc or choose the 1/2" , 18 port manabloc? Or does the fittings all one standard size?
Asked by Danny 16 years ago
Add your answer
Verified Reply- PexSupply StaffIf you have a MANABLOC that has some 1/2" and 3/8", then you need to order a unit that has both 1/2" and 3/8". The ports are not the same size.

Q: The Manabloc tech sheet shows 1" inlets. If the hot and cold water supply line is 3/4" can the manifold be stepped down without losing capability? If not, are there manifolds with 3/4" inlets?
Asked by Go Steelers 16 years ago
Add your answer
Verified Reply- PexSupply StaffThe thread on the manabloc is specific to the unit and isn't quote 3/4" or 1" which is why supply adapters are required for every supply line connection. You can make a 3/4" connection to all of these units without losing any capability by using the supply adapters that can be found on our website here: http://www.pexsupply.com/pex/control/category/~category_id=764/~refine=200764+4294959093 .

Q: The diagram in the PDF below shows the cold water flow to come in from the bottom. It was stated above that the top inlet can be used for cold water inlet and the bottom can be capped. Is this accurate? Is there any reason why you couldn't use top or bottom as the cold water inlet? http://s3.pexsupply.com/manuals/1274210084669/30816_PROD_FILE.pdf

You can use either one. The front cover comes off so you can mount it either way.

Q: I am remodeling a house that i just bought and wanted replace the old galvanized piping with pex. i'm just slightly confused about the manifold system and how to install it. i see that it has a cold and hot water inlet on the top but what is the pipe for on the bottom of the manifold? It is also a single level home and wanted to know if it would be better to run the pex under the house or in the ceiling joist? Thank you
Asked by Aaron 16 years ago
Add your answer
Verified Reply- PexSupply StaffThe third supply port at the bottom of the unit is for recirculation of a cold line and often times is not used in a standard plumbing application. To configure the system to only use the hot and cold lines at the top of the unit, a supply end cap is needed to plug up the additional port. It can be found here: http://www.pexsupply.com/Viega-53601-MANABLOC-Supply-End-Cap-5418000-p . It would be best to run the PEX in the area that will have the better insulation. This will help the PEX from freezing and will cause the PEX to sweat less.
