In a tighter space, an all PEX manifold might not be a good option. Even if you place outlets on both sides of the “D” you are using the full bay for just the cold water line. We are looking at something at least five feet long without anything else attached at either end. Just 4.1” x 12 = 4’ 1.2”–without the connecting PEX-a. Now imagine putting an all PEX manifold together: a series of 4.1” long ProPEX 1″ x 1″ x 1/2″ reducing tee and a length of pex between the tee’s. Center to center between each valve is 1.5”. The 12 count 1/2″ ball valve manifold you see here is 19.5” long. However, the downside is the massive size. Another economical solution is to create an all PEX manifold.Įasy to service and detect leaks, it is a decent solution if expense is a problem. If you end up replacing a faulty manabloc you are out an additional manabloc too. So for the price of a copper and brass manifold you are saving yourself an undetermined dollar amount plumber visit. ![]() Each hour of a plumber’s time is worth a decent chunk of change. In comparison, it is easy to detect the source of the leak on a copper and brass manifold. We’ll save up for the ring later…īack to our master plumbers’ experience…their other point is that they might spend hours troubleshooting a broken manabloc. Sweetheart, would you rather have a ring or a manifold? Me: You had me at manifold. It could be considered an engagement ring to your house if this is your forever home. I don’t want to install something that becomes someone else’s problem later on. We’re buying a high quality product that won’t fail years down the road. Margaret, what are you thinking?!?! Look at the price difference between a copper manifold and a manabloc?!?! ![]() Otherwise, you’re looking at replacing the manabloc. You hope it is as simple as closing off one of the lines and moving the line onto a different port. Their experience has been that a manabloc style manifold with plastic, gaskets, and a more or less hidden interior is difficult to pinpoint a leak. In an all brass/copper manifold system, if a leak occurs it is easy to discover the source. No plastic with gaskets / washers that will eventually break down and spring a leak. Their recommendation: spend the extra to go with an all brass/copper manifold system. We reached out to a few master plumbers who are paid to FIX these manifolds down the road. In this case, we defaulted to experience. The next decision is what kind of a manifold is best. ![]() With different sizes needed throughout an entire house, piecing together a full manifold is the only way. Generally they are used in a trunk and branch system where the manifold branches, let’s say, a couple bathrooms that are close in proximity, off of a single line. Mini manifolds only come in a set in the same size. Combine that with your half inch lines to your faucets and you have a mix of different sized plumbing. Got one, two or three exterior spigots? Whatever number, you need a higher water pressure/ volume 3/4 inch line. You probably have any combination of ½” and ¾” and 1” jumps coming off the main supply. You can buy what I would call–in nontechnical terms–a mini manifold off the shelf, like this one, but we’re talking about a whole house manifold here in this post. The next question is, “What kind?” Just to clarify the use of the word “manifold”– Drop a note/comment if you have any questions on the products as these are materials and tools we use on our own projects.Īt this point in your build or remodel you have already decided on installing a manifold plumbing system. The important thing is you will know exactly what we are talking about. Some are, some aren't-I do some comparison shopping. **Our honesty policy: This post may contain affiliate links and I may be compensated if you make a purchase at no extra cost to you.
