Water Distribution Manifold Design

Home run manifold systems use the least hot water and the most pipe.

Water distribution manifold design. A large diameter 3 4 in main water line feeds the manifold. An example pex water manifold design. Manifolds serve as control centers that deliver hot and cold water to flexible pex supply lines running from the manifold to individual fixtures. The flow in manifolds is extensively encountered in many industrial processes when it is necessary to distribute a large fluid stream into several parallel streams and then to collect them into one discharge stream such as fuel cells plate heat exchanger radial flow reactor and irrigation.

If topographic conditions are ideal gravity distribution is used. Each pex line is a home run to a. Dividing combining z type and. This water distribution system is often the major investment of a municipal waterworks.

Pex plumbing manifolds and pex tubing are part of a relatively new method for residential water distribution but they have gained wide acceptance in the home building industry. Water manifolds are regularly used in home plumbing. Extensive water distribution system is needed to deliver water to the individual consumer in the required quantity and under a satisfactory pressure. They are control centers that control how water is distributed to parts of the house.

Manifolds can usually be categorized into one of the following types. Any fixture in the house can be shut off at the manifold. How to build a whole house uponor pex a manifold. And because home run systems don t rely on a large pipe for distribution you save both water and energy.

Parallel water distribution manifold plumbing home run protection of tubing and fittings from uv exposure after the. We ve been asked a couple times to diagram the outlets in the pex water manifold we shared here. 2 0 design 8 2 1 water demand 8 2 2 water distribution systems 10 2 3 water distribution modeling 11 2 4 pumps 13 2 5 valves 17 2 6 tanks and reservoirs 18 2 7 controls devices 19 2 8 epa 20 3 0 laying out a project 21 3 1 existing data 22 3 2 schematic generally 22. This house has a manifold cabinet with both the hot and cold water lines housed together on an interior wet wall of the house.

Smaller lines run from the manifold to each fixture.
