I'm not sure if multiple floor drains in auto repair garage should be trapped vented if they flow to an oil interceptor which is trapped and vented.
i have about 16 trench drains spaced about 50 ft apart in a slab on grade installation.
they receive no other drainage
The code says floor drains within 15 ft of vented fixture do not require vents. i thought this might be for a situation in a bathroom with a floor drain
