Floor Drain placement

[CJUDGE]

Wow you must be bored if you are reading this.

I am in planning phase of 32 ft deep x 30 garage in Florida.

Wondering about experiences with a floor drain in the center of one bay vs. a long drain grate near both doors?

Planning on open race deck flooring..

Any thought of one vs the other ?

What type of drain covers work well.

Mostly the garage will be car cleaning and maintenance not a heavy duty restoration.

Thanks in advance.

Not bored but taking a break from wall prep for the painter in my shop on Monday.

I put 8" stainless steel cover sediment basket drains in my garage/shop, two of them. I have a 30d x 35w and placed them in the center of each half. My concrete finishers ran the floor level 5'-0" from the three walls out then pitched to the drains that I had set about 1" below finish floor. At the rollup doors they pitched to the drain. When I pull in my RAM ProMaster van (huge) and it's covered with snow the melt off runs perfect to the drains without any birdbaths. Those Stainless drains were sitting on my yard for 20 years waiting for this install. I would imagine they may be about $500 each to buy now. I got them for free.

Thanks. That is an interesting idea.

I suggest you check with your local permit office. Chances are good that floor drains are not permitted.

I've learned to never underestimate the stupidity of the local building code office, but what is the logic behind NOT allowing them?

Seems if you can get water away from your property that is a good thing, and something they would endorse.

There is no "perfect" placement for a floor drain, IMO.
Currently I have 8' of 5" channel drain in the center of a bay so snow/water drains off the car and I can use it as a wash bay. The bay with the hoist is flat.

In the past I've had the channel drain run parallel to the overhead door and in another it ran between the two bays.

This is they type I've used:
channel drain

It's not the water they are concerned with. It's everything else. Usually if you are allowed to have them they specifically can't drain off of your property or even into ditches or swales that run off of your property.

Common sense and rational thinking is something the administrative regulatory agencies are not familiar, judging by the obtuse rules they seem to arrive at, and which they wish to burden us with.
Parking one's vehicle and letting nature melt away snow or rain wash the mud covered cars is no different than doing the same yourself and letting the mud and snow go where they may. If your run-off has no affect upon the public, it's no harm, no foul and those evil agencies should simply bug off and leave us alone.

Yes you will have to find out your local code.. My town didn't allow them for years, but recently went back to saying they're ok.. Mine is in the centre- it's 12"x12" as a sand catch, with a 3" pipe up the centre.. So the sand stays in the box, and only water goes down the pipe. My floor is tapered 2" from the outside edge to the centre, and that is just enough.

I have 2 floor drai s in my 32'x 40 pole barn spaced evenly in the center of the 2 32'x20 sections. I just built a 32' x56 shop and no drains.

I take it that you made the cover? Nice work on the logo.....

Permit/Codes aside, I have 3 centre drains in my 32 x 42 garage (one for each stall) and a level floor. I need to squeegee an awful lot when the snow is melting off the vehicles because of that.

If I were to do it again, I think a gutter in front of the doors would be the way to go this way all the water drains back and you have a dry space up by the bench.

That would be correct.

In most Florida developments your property must be graded to capture and contain any rain/storm runoff on YOUR property.

Further to this: If your drain will connect to the sewer, what's your plan for keeping water in the trap?
