PEX manifold is a copper tube like structure with many outlets and a single inlet. Manifolds are used to divert water, gas or any fluid to different parts of the house or a building. The main line of flow is distributed to many parts as per the requirement. PEX manifold with spin closed valve is a plumbing device used for home floor heating system mostly. Its outlet size is half an inch and is compatible with the PEX pipes which are most suitable with floor heating system. It has a 3 /4 “crimp style PEX inlet.
There are different kinds of PEX manifold systems used for different purposes. The copper pipe is of one inch and is closed at one end. It can not be used in the middle of a line as the other end is closed. The water in this kind of manifold can open only in one direction. The outlets are evenly spaced out. The distance between two outlets is about two inches.
The valve of the plumbing manifold with valve spin closed is like a ball in the pipe which has a hole in the center. When the hole is aligned with the sides of the pipes the water flows and when it is turned the water flow is stopped. The valves have a handle which has to be turned physically to control the flow in the pipe. There are PEX manifold with valves with four, five and six outlets. Manifolds are also used to collect water from different areas and sent to one collection container. In case of the floor heating systems the water from different rooms get back to the boiler through a manifold.
The pipes attached to a copper spin closed manifold can be demarcated so that it becomes easier to locate any trouble or to shut down a part of the house with out troubling the rest of the area. Flow of water through individual pipes can be shut down by turning off the valve. This feature is helpful in keeping the electricity bills low and to repair any damages. The PEX pipes used for the purpose of floor heating is also a good retainer of heat which adds to the reduction of the bill. The valve system is convenient to keep the water in the adjacent pipe flowing while the one damaged can be replaced without any hassle. The adjustable claps or brackets are also available to keep the manifold in place.
