Plumbing Trends: PEX Piping Layout & Methods
| Piping Layout & Installation - Overview & Comparison | |||
| When designing or installing a PEX plumbing system, you will first have to decide on the layout and method of installation. Here outlines the three most common types of PEX plumbing layouts for review. In order to choose the layout and method that best satifies the jobsite requirements you will consider the factors relevant to your priorities. | |||
PIPING METHODS | LAYOUT DESCRIPTION | ||
| Trunk & Branch (Conventional) 傳統(tǒng)式 |  | Conventional or Trunk & Branch Method is the same method used in rigid plumbing systems. Running PEX tubing in the Conventional Method requires the installation of a main trunk line which branches to specific outlets. This method does reduce the total linear feet of tubing used; however, it does require more fittings, which can increase cost and installation time. | |
| Multi-Port Tee (Hybrid) 複合式 |  | Multi-Port T Method combines the benefits of the Conventional and Home Run Methods. Multi-Port T Method runs individual branch lines from smaller manifold located near groups of fixtures. This effectively reduces the length of total tubing used on the job, while minimizing the number of fittings required for Conventional Method of Installation. | |
| Home-Run (Parallel) 一管到底 |  | Home Run or Parallel Method distributes water to each fixture from a centrally located manifold. The manifold is typically located close to the hot water source in order to provide fast and efficient hot water delivery. The Home Run Method provides a dedicated line from the manifold to the fixture which reduces the need for fittings behind the wall. | |
| CONSIDERATIONS↓ PERFORMANCE→ | OPTIMAL | ADVANCED | TYPICAL |
| Minimize Pipe Used | Trunk & Branch | Multi-Port T | Home-Run |
| Minimize Fittings & Joints | Home-Run | Multi-Port T | Trunk & Branch |
| Sequential Flow Hot Water Delivery Time | Trunk & Branch / Multi-Port T | Home-Run | |
| Minimize Hot Water Wait Time | Home-Run | Multi-Port T | Trunk & Branch |
| Single Fixture Pressure | Trunk & Branch | Home-Run / Multi-Port T | |
| Pressure Stability with Use of Multiple Fictures | Home-Run | Multi-Port T | Trunk & Branch |
| Centralize Shut-Off Valving | Home-Run | Multi-Port T | Trunk & Branch |
| Joint Accessibility During Installation | Home-Run | Multi-Port T | Trunk & Branch |
