Garage Floor Drain Placement

[goose89]

Need advice for placement of "trench" floor drain in double garage that will be poured soon. YES, where I live, garage floor drains are legal.

Contractor has it dug out (easily changed) "vertically" in center of garage. IE: Between both vehicles.

I'm used to seeing most "trench" floor drains a bit inside the garage door, running "horizontally" IE - Have to drive across them.

Garage will be heated. Will be draining to daylight out the North end of the garage....Garage doors are at the South end of garage.

The only advantage to doing it the way it's set up now, that I can see, is that we won't be driving over it ever.

I'm not crazy about wife walking through the area that both vehicles will be draining into...If there's some wisdom to this set up, I'd do it. If direction of run is an issue (running North & South vs. East & West, like I"m used to) would it be worth the extra $$ to put one under each vehicle??

btw, we're also putting one in 3rd stall, running vertically, under boat, just like I want it....just not sure what to do in double, car area.

It's an NDS Pro trench floor drain. Plastic grates for now....I believe they can be replaced with galvanized / SS steel.

Any experiences / advice would be appreciated! Thanks in advance, Mike

Doesn't it make sence to put the drain by the doors because that's the way the floor slopes?

That's where I've put them and they worked great.

Unless you slope towards the drains In the middle.

Personally I've had one between the vehicles and I hated tripping over it(but of course it wasn't the brand/style you're installing).

If you don't mind a slightly wavy floor(for drainage) then I'd put one under each vehicle going front to back. If you'd rather have a smooth floor with no obstructions then place it at the doors.

I'd put one under each vehicle so you aren't tripping over them. We always run them perpendicular to the vehicles.

They will slope the garage floor back toward the drain from the garage door. Make absolutely sure that when they pour the floor anything outside the door itself is sloped to the outside. Otherwise you will have rain and melting snow running into your garage under the door.

Thanks for replies so far guys....leaning towards horizontal just inside garage door....not gonna do the wavy floor verical under each vehicle....anyone have a good reason to put it "vertical" between the vehicles, running down center of garage....right where wife gets out of car??

My neighbor trenched right in side his door like you said for his garage and the guy next door. Worked great.

I've gone back to original, down the center, between the vehicles plan...couple of good reasons kinda unique to my situation...the horizontal, just inside the door works for many, I'm sure, but not the best in my case. Thanks for replies.

I would want to make sure that the ladies don't have to step on it in case they're wearing any sort of heels. If her car is parked on the left then your center plan should work OK.

How are you going to have it exit so that it doesn't freeze up on you?

Personally I'd stick to the old way close to the door,You could get a steeper slope,which would keep the working area drier,access to a vehicle could be made from walking around the non drain side of garage,Sweeping and keeping debris out of a drain at the doors would be easier sweep to mid building and pick it up.Counfortable open floor to walk through.no dodging grates
