Modular backflow prevention system

摘要

A modular backflow prevention system for a sprinkler system includes a first fixed union end piece attached to a first end of a fixed water inlet pipe through a first union mating adapter where a second end of the fixed water inlet pipe is in fluid communication with a water supply. A fixed union end piece with seal is attached to a first end of a fixed water outlet pipe where a second end of the fixed water outlet pipe is in fluid communication with the sprinkler system. A removably backflow prevention assembly is removably attached to the first end of the fixed water inlet pipe and the first end of the fixed water outlet pipe by removably attaching a second union mating adapter to a second union end of an inline ball valve and removably attaching a third union mating adapter to the fixed union end piece with seal.

主权项

1. A method of modularizing a backflow prevention assembly of a sprinkler system comprising:
cutting a water inlet pipe forming a fixed water inlet pipe and a removable water inlet pipe; cutting a water outlet pipe forming a fixed water outlet pipe and a removable water outlet pipe; removing the backflow prevention assembly; attaching a first fixed union end piece to a first end of the fixed water inlet pipe through a first union mating adapter, wherein a second end of the fixed water inlet pipe is in fluid communication with a water supply; removably attaching a first union end of an inline ball valve to the first union mating adapter; attaching a first fixed union end piece with a seal to a first end of the fixed water outlet pipe, wherein a second end of the fixed water outlet pipe is in fluid communication with the sprinkler system; attaching a second fixed union end piece to a second end of the removable water inlet pipe through a second union mating adapter; attaching a third fixed union end piece to a second end of the removable water outlet pipe through a third union mating adapter; and capping the fixed water inlet pipe by removably attaching a fourth union matting adapter to a second union end of the inline ball valve and removably attaching a first removable cap to a first removable union end piece through the fourth union mating adapter.
