How to make shop floor drain

Randy

Might want to check local codes if you're in the city limits.

Thanks!

Having a drain go to the opening for the overhead door might work well in some areas, but here where it sometimes gets extremely cold, I would worry about it freezing and maybe breaking in the winter. Also, just draining to the outside might allow mice or other critters an easy way in.

There is no better time to put in a drain system than now. I would suggest talking it over with whoever is doing your floor, and if they aren't pretty sure they can do it right, you might want to get someone else. There is a lot of "art" in doing flatwork. You want to get it right the first time... Good luck, let us know how it comes out!

Slope the floor toward the door ( not more than an inch in 10 ft) , put a small trough across

inside the door with a drain in the trough to the

outside , cover the trough with grating.

If youare ever going to use a creeper , a jack

or a floor jack in the bay , DO NOT use a 4 way

slope to a drain , those 4 way slopes are for

looks not practicality. Creeper run down hill,

jacks tip over , and floor jacks buckle over

and are destroyed.

Also take a 2nd look at anything else you may want to stub up for in this new shop, in the future, like mechanical, electrical, communication, and or plumbing as well, even if just left for future use, lot easier than chopping and digging later.

I never realized that my dad plumbed in the waste pipe to the septic system for a toilet in what was supposed to be a mud room in the cellar when the house was built in the late 70's. I was suprised to find the toilet flange so I just added the water lines and bolted on a toilet, grouted it to the slab in '04, sure made it an easy task to make another bathroom in the house, convienently located in the cellar which is actually what I use for a garage and work shop, am very fortunate to have a space that would fit 4 cars and stays about 55 deg in the winter, with another equal sized area beyond that, now if I just had a higher ceiling, LOL ! I can almost squeeze my F-600 in, if I let some air of the tires.

Also consider where the drain pipe will lead to, this one here daylights to the surface 100 yds away and mostly evaporates on the surface, the area stays wet and is probably a mosquito haven. I should put another dry well in, I don't wash anything harsh down the drain, just water and rarely some suds. We kept all of our waste lines seperate, toilets only to the septic no other waste water, all other waste water only to the seperate dry well, both are oversized and have performed great for almost 30 years.

Couple of thoughts here, it's always good to get suggestions when building, might help you avoid forgetting something important, prompt you to think of something useful to have or even just a better way of doing something.
