View Full Version : Carpet in the basement

I have a partially finished partially finished basement. Right now, the floor is tiled (vinyl, might even be asbestos judging by the style and size (9" x 9")) as it was when we bought the joint ten years ago... I was planning on buying some low pile, high traffic carpet and installing it down there.

So my colleague comes up to me today and tells me that a window got busted in his basement, causing his sump pump pipe (the one that kicks the water out) to become dislodged and spray against the wall, running onto the floor. Then he says it: "The idiot that did the basement before we bought the place carpetted the floor and ran right over the floor drains...

That's what I was planning on doing. Just something so it wasn't a cold tile floor. About 10% of the basement (by the laundry and the downstairs bath) is ceramic tile and another 5% (by the furnace, water heater, etc) is the bare concrete floor. I have two floor drains (not including the shower stall): one in the vinyl tiled area that I want to carpet and one in the ceramic tiled area, where a water tank bursting or a washing machine overflow would most likely run.

Is covering this floor drain a bad idea? Is there a work around?

Another thing... my father in law warned me that the water in floor drain traps will eventually evaporate if they aren't used much, leading to stink emanating from the floor (the release of gases that the trap is meant to "trap"). The problem is a simple fix...just "refill" the trap by pouring water down the drain.

But if I carpet over the drain, I can't replenish the trap water... will that stink seep through my carpet? Should a cap the drain?

They have devices called trap primers(I think) which basically drip water into the trap, probably would be a big mess to cut through the concrete to run a supply line to install the trap primer. Just so you could carpet over it. Normally the floors are poured to aim the water at the drains. It is very possible that if you just cap it, if you did have a water issue it would all pool right where the capped drain is. They do have carpet "squares" that interlock like a puzzle, and once all together you are not supposed to bo able to see the seams. Could do those and if you start smelling sewer gas thru a dry pipe could always just take up the square covering it and pour some water down there. also if there is ever a leak or some thing you could quickly get the carpet up and be able to dry everything out with the drain intact. This assumes no carpet pad, but now that I type that the squares my have built in pad. Not sure. I like to ramble, hope I helped more than wasted your time.

I've seen those carpet squares... that's an idea.

Basement floor is definitely graded to run to the drain...

You could also get a more decorative drain cover--brass or chrome--and just cut a hole in the carpet for your drain. That way, it is at least functional and you can easily access it.

Another option is to use what we do at work for flor drains that manage to dry out and stink on a regular basis. we dump a comercial chamical down it and it wont evaporate. it is basicly just an expensive form of RV antifreeze. Just dump between a quart to 1/2 gallon down there and you should never have to worry about it stinking because the glycol will not evaporate like water.
