#Pex manifold system series#

Outlets on the Viega manifolds are either PEX Crimp, Press or Compression type and are likewise compatible with all types of PEX as well as Viega FostaPEX (press version only).

Q: Which tubing types and brands are these manifolds compatible with?Ī: Outlets on the Sioux Chief PEX plumbing manifolds we carry are crimp style (per ASTM F1807/F877 standard) and are compatible with all types of tubing (PEX-a,b,c), except PEX-AL-PEX. Under normal conditions, these manifolds are intended for PEX plumbing only. While ManaBloc is a whole-house manifold, designed to handle anywhere from 6 to 14 (and more) fixtures, the MiniBloc version is mostly used to branch off a main hot/cold water line and provide water to a single bathroom, guest house, small apartment, etc - with anywhere from 2 to 8 fixtures.įrequently Asked Questions: Q: Can I use PEX copper manifolds for radiant floor heating?Ī: Radiant heating applications generally require balancing valves or other means of flow/temperature regulation, which copper manifolds don't have, so we do not recommend the use of these manifolds for floor heating applications unless proper system balancing is present.

The main difference between the ManaBloc and MiniBloc series is the number of outlets (or branches). Viega was first to introduce the concept of a 'home-run' manifold system, where both hot and cold water manifolds were combined into a single compact unit, with added functionality of individual branch shut-off valves and simple, yet versatile, mounting options. About ManaBloc and MiniBloc poly alloy manifolds by Viega

“Open” manifolds are flow-through and have open outlets on both ends.īranches are spaced at 2' apart on all PEX models and 3' apart for regular models with sweat outlets. “Closed” manifolds have a spin closed trunk on one end of the manifold. Inlet/outlet options include PEX or sweat connections in sizes from 3/4' to 2' sizes. Regular models without valves have either crimp or push-to-connect outlets. Valved models have 1/4'-turn shut-off miniature ball valves permanently soldered over the manifold’s branches. PEX tubing can also be bundled as the lines snake through the house.About PEX copper manifolds by Sioux ChiefAll Sioux Chief manifolds can be divided into two main categories: PEX Manifolds with Valves and Valveless Manifolds. PEX tubing works great with a manifold system, and red and blue colored PEX can be used to signify hot or cold water. When you add in the water saving nature of PEX tubing, this becomes an even bigger factor.

The individual ½ inch runs use a lot less water and save quite a bit of energy because the user is not having to clear out a ¾ inch line before hot water reaches the fixtures. Water pipes running in marginally conditioned or unconditioned areas also exacerbate this condition.Īll of which leads us to manifold systems: a green building technology that mitigates this by using ½ inch take-offs very close to the hot water supply. Coupled with the inefficient water heating systems that are the standard in most homes, the result is an energy and water equation that is working against the homeowner. A larger diameter pipe takes more than twice the amount of hot water to supply a remote fixture than an equivalent ½ inch pipe.Īs our homes have become larger with more bathrooms and longer plumbing runs, this makes the problem far greater. For hot water supply, this is an extremely inefficient use of water. A traditional plumbing system uses a ¾ inch diameter pipe (or even larger for big homes) that makes a circuit around the house with smaller diameter ½ inch pipes coming off to supply individual fixtures.
