Hi everyone,

I am installing a new basement floor drain, without a vent. Per the local plumbing code:

A trap that serves a floor drain or hub drain need not be protected by a vent pipe separately where,
(a) the size of the trap is not less than 3 in.,
(b) the length of the fixture drain is not less than 450 mm,
(c) the fall on the fixture drain does not exceed its size, and
(d) the trap is connected to a horizontal drainage pipe that terminates at its upstream end in a 3 in. stack.​

I am able to satisfy (a) - (c), but with the basement being finished I am unable to verify (d). I plan on accessing the main 4" sanitary line 1-2 ft. upstream of the backwater valve. The house was built 5 years ago. Is there any situation in which condition (d) would not be satisfied in my case?

Thank you

Best course of action would be to verify condition (d) via either opening up drywall or sending a camera upstream from the backwater valve.
