Questions on floor drains

[nickm1024cobra]

This may sound basic or elementary but I have a couple questions.

If I put a drain in my garage, what are my options to discharge this drain? I realize it may depend on the code, but what are all the options.
New construction.

Outside of purchasing the actual drains, what else would i need to purchase to setup the system.

Thanks!

I'm going to go ahead and make some assumptions here. If you're asking to put a drain in your garage, you're doing it yourself.... And probably not doing it up to code in your particular area ( since you're asking, opposed to looking at the code for your area or asking your GC).

If you're using a concrete guy or a GC, they should be able to answer these questions for you without any problems. As well as provide the trough.

I'm guessing they drain into the house waste water pipe leading out to the sewer system. I've heard in most areas they're frowned upon as idiots pour things like oil down the drain, not realizing its bad.

If the garage sits high enough you could daylight the drain on the exterior. Lots of inspectors will want to see an oil interceptor if your connecting into the sanitary sewer.

I spoke to my builder about it and I can get it approved by the town. I just had not thought about options on where it would drain. If daylight or tying into sewer what do you guys recommend and are either going to cost significantly more? I'm on well and septic with a relatively flat lot if that matters. Water is all that is headed down the drain.

I wouldn't want to tie a garage drain to my septic system. Sure as **** you'll have a spill of something that kills your septic system and then you have a problem. Mine are daylighted.

I have my two drains connected together and they run through the side wall block, a 90 degree elbow and discharge into the shake backfill along the foundation.

I hate referencing code, but if it gets inspected, they will require a sand and oil interceptor before discharge. They don't want either one in their pipes!
Epa is harsh on daylighting the drain and dumping into or on the ground, don't even try that.
Honestly most of us got our rebar inspections complete and before pouring, we put in a drain line, as simple as a pipe with a 90 degree elbow looking up Same as a shower except no p trap underground, run the pipe below grade to a point outside the building capped both ends. Then pour over the top of the elbow so it's no visible (a 1/4" below finished floor) keeping measurements where it is at. Then after your final inspection, take your hammer and chip the concrete off the top of the elbow, go outside the building dig up the end of the pipe and add your means of disposal. That depends on soil type. In sandy soil, did a hole, bury a plastic barrel with drain holes in it, wrapped in drain wrap material. Back fill with rock to just below grade, cover rock with cloth and final grade with soil. Have your drain penetrate the side of the barrel near the top. You are done.
Honestly to get approval and inspection could cost 10's of thousands of dollars, that's why you don't see drains in residential garages.
Good luck.

The reason we put drains in our garages is for snow/slush and other daily driven car **** that comes in the garage to be flushed out.

However, there are skunks that would always look for easier and cheaper ways of doing things like draining used oil in those drains

I have 6 garage bays in my on going project and they all have drains that open up to the exterior.
