We are adding a vertical backflow preventer to my riser assembly.
What minimum dimension do I need for the closet doors to keep it accessible for testing and maintenance? If there are large doors, can the doors be adjacent to the backlfow and open to provide the access to the backflow? Sent in anonymously for discussion.

We usually give 12" behind, 24" clear above, 36" clear in front and anywhere from 30"-60" above finished floor if double check is in horizontal position.

In addition, if you are installing in a tight cabinet or closet, I use the door (when open) as your clear space in front of the assembly. Just ensure you have adequate access to reach around and work behind the assembly.

Backflow prevention will have clearances spelled out in the plumbing code and by the health department.

open doors count for access clearances here in this part of the world ... better make sure you have minimum egress width in corridor (if in corridor) while doors are open or you will violate the fire marshal's wishes ...

Door opened will count as clearance in front of the BFP. Do remember the forward flow test connection that is also required. Leave a Reply. |
