Product Q&A
50 QuestionsQ: Are these manifolds expandable? Can you replace individual modules?
Asked by PatrickM 10 years ago
Add your answer
Verified Reply- Supplyhouse StaffThey are not expandable on the actual port and are not available for individual replacement.
Not expandable unless you string 2 in line. You cannot add ports. Michael Palcisco Please consider the environment before printing this email
NOT expandable and still maintain the warranty.... disassembly will void the warranty. As far as I know, viega does not sell individual modules.
It takes a little plumbing but you can add another. You must have a hughe house
The answer is no to both. Individual outlet valves are replaceable. Sent from Greg's iPad
Q: What is the height of the manabloc SKU 36636 the 36 port 1/2" 3/8" manabloc? Also is it possible to pick and choose which ports to would be 1/2" and which ones 3/8"?
Asked by shah 11 years ago
Add your answer
Verified Reply- SupplyHouse StaffThe 36 port manabloc is about 34 and 3/8" in "height" from the top of the unit to the bottom connection. The manabloc is set up for the specific ports from the factory, so there is no way to change which ports are 1/2" and which are 3/8" it only comes set up the one way.
Approx 30" tall. You cannot choose which port is 1/2 or 3/8. They are preset Michael Palcisco Please consider the environment before printing this email
Q: Is there a divider plate between the upper 9 cold water connections and the lower 6 cold water connections? I have a hard water feed and a soft water feed for my current system.

Verified Reply- SupplyHouse StaffNo, the cold connections on this manabloc are all connected.
Q: I found out about this unit via you tube video and was shocked at how easy it looks. One thing the video shows is, transition fitting for this unit along with inlet cap. My question is, do these items come with the unit

Verified Reply- PexSupply StaffAll fittings for the 1/2" outlets are included, but supply adapter fittings and a supply end cap are not included.
I believe I know what you are talking about and the answer is no! I purchased a regular 3/4 inch threaded pex fitting and used a shark bite fitting for the transition! Sent from my iPhone
You need to use Manabloc supply adapters because they Manabloc has proprietary threads. Supply adapters are not included with the manifold because there are different sizes and connection methods available. This video may also be helpful: http://www.youtube.com/watch?v=nEqAo3bqJsk
Not sure what the "transition fitting" is but I bought and installed this manifold in my new home and everything I needed to attach my ½ inch pex domestic water lines was included. I did not get a wrench to tighten the hex nut as the tubing is tightened onto the threads and that would have been helpful but I have a large crescent and that works as well it's just slower.
Q: What is the bottom port for on a manabloc

Verified Reply- PexSupply StaffCheck out our blog post, we have diagrams that should give you a better idea of the supply options for manablocs : http://blog.pexsupply.com/when-to-use-supply-end-caps-on-viega-manablocs/
Q: The Viega 36303 indicates that it can accommodate 3/8" or 1/2" distribution ports. How is this accomplished? Is there a reducer attached to the standard 1/2" distribution port to get it to 3/8" or do you have to specify whether you want 1/2" or 3/8" ports when you order it? Can you mix the two sizes in the manifold?
Asked by Rodge 14 years ago

Verified Reply- PexSupply StaffMANABLOCs in general (including compression models) can accommodate 3/8" or 1/2" outlet lines, but you need to specify what you want prior to purchasing a compression MANABLOC. There are two types of thread that you'll find on MANABLOC outlet ports: one that works with 3/8" compression fittings and one that works with everything else (i.e. 1/2" compression, press, & crimp; and 3/8" press & crimp). This means that you can buy interchangeable port fittings after ordering the MANABLOC, unless 3/8" compression is in the mix. For this reason, Viega offers "combination" compression MANABLOCs with some 1/2" and some 3/8" ports.
I have only ever used 1/2" port and line. I think there are 1/2 port compression fittings for 3/8 line. But why use 3/8 line? Please consider the environment before printing this email
Q: I intend to install two 14 port Manablocs,of the compression connect type. One Manabloc to handle 1/2 inch pex and the other to handle 3/8 inch pex,plumbing fixtures as suggested by the Viega Manabloc manual in regards to point of use,ie: 3/8" for bathroom sink and 1/2" for tubs and shower as examples. Will such use be complicated due to need to split the water supplies,both hot and cold? If that causes problems what can be done to overcome said problems? I intend to use a plumber for the install but would like to go ahead and order the devices, pex and fittings.Thank you

Verified Reply- PexSupply StaffSplitting the supplies would not be a problem. You would still have the same amount of water feeding the same number of fixtures. You may also want to consider a "combination" compression MANABLOC, which has some 1/2" and some 3/8" distribution ports. The biggest problem with using 3/8" tubing is that it is difficult to find fittings to make connections at fixtures.
Q: I have a Vanguard 36 Port compression MANABLOC (installed 1990). It has the hot and cold ports opposite that which are shown in the picture. A port has started to leak, so I guess I need to replace the entire unit. What part should I order so that when the single supply port is at the bottom the hot ports are on the top right and the cold ports are on the left and 4 bottom right?
Asked by Dan 14 years ago
Add your answer
Verified Reply- PexSupply StaffCurrent MANABLOCs all place the hot ports along the left side. One possible solution would be to use the red ports for cold and the blue ports for hot. You can do this as long as you don't plan to feed cold water to your water heater through the MANABLOC.
You could look into rebuilding the existing leaking port or see if manablock custom builds manifolds. Short of sheer luck, i doubt the very same configuration exists from any manufacturer than yours. Please consider the environment before printing this email
Honestly - no idea. The setup you describe is opposite from how Manablocks are made currently. You may want to contact the company directly to see if they can reverse the hot and cold port banks for you. Good luck.
Q: What is the proper procedure for start-up of the manifold. I am converting an existing house over and want to start up one fixture at a time. Can initial water pressure be applied without having any of the port valves open?
Asked by Dean 14 years ago
Add your answer
Upon completion of my connections, that is, supply, water heater and runs, I turned on the main then worked the air out of the system one run at a time. Accordingly, all ports were closed initially. This should not be a problem with the Manabloc system. It's great!!
the installation manual state open all value that you are using before pressurizing or damage may occur if you must open one under pressure open slowly a little until line is fully pressured then open fully
The manifold is just a series of valves. It doesn't know the difference if your project is complete or not. Be sure you have the caps to close off the manifold through piping at the top or bottom. Where you put the caps depends on if you feed it from the top or bottom. You will love this thing. I have two. One for a basement apartment and one for the upstairs. This way i can have two water heaters which are on separate electrical feeds and meters.
yes, air will be forced out as you open ports individually.
Yes you should be fine, one at a time or none.
Any or all valves can be closed... assuming that your house water pressure is in the normal working range.
Q: Can I connect female hose fittings to my Manabloc to connect dishwasher and icemaker with copper pipe?
Asked by Plumb Bum 14 years ago
Add your answer
Verified Reply- PexSupply StaffYou wouldn't be able to connect hose fittings or copper fittings directly to the MANABLOC, but you could transition from PEX to copper in the line or use PEX dishwasher/ice maker valves.
No, you shouldn't. Run your pex lines to the wall behind the dishwasher and fridge, then add a fitting to run your copper from there.
I wouldn't rely on a hose connector to be leak-free, even if the threads match (which they probably do not). If the threads do not match, you risk problems of cross-threading the port, making it difficult to ever get a good compression fit in the future. Ideally, I would come out of the Manabloc with 1/2" Pex, and then use a "Sharkbite" or similar coupling to transition to copper without the need for solder. If I was missing the original compression parts, and couldn't replace them easily, rather than trying to connect to the manifold with a hose fitting, I would TEE off of some of the correctly connected branches. Pick the branch from the lowest-use hot port for the dishwasher (like the lavatory for a 1/2-bath), but pretty much any cold branch for the icemaker would be okay. If you've misplaced some of the hardware that came with the Manabloc, you should be able to obtain spares from a Viega supplier.
