Product FAQ

Is the Z550 drain available with an 8" outlet?

  • Floor drains are typically sized based on the flow rate that can pass through the attached piping.  The Z550 features a grate with 18 square inches of open area, while an 8" pipe has roughly 50 square inches of open area.  In this case, the grate would severely restrict the flow to the 8" pipe.  When a similar drain is needed for 8" pipe, specify the Z505.​
