After the Big Room Move of 2009/2010 (blog post on that coming soon), Jen and I have been spending more time in our back room here at home. This is where the computers are, and we spend more time in front of our computers than pretty much anywhere else. Right outside the door to our new studio/computer room is a small utility area, complete with washer/dryer hookups. We don’t have a washer or a dryer. Instead, we use the utility space for media storage. And since we’re not using the space for its intended use, that means those washer/dryer hookups are also not in use. And for awhile, that was no big deal. But since we started spending more time back here, we noticed something. Something foul. A terrible smell that would occasionally creep into the room. Theories were proclaimed as to the possible source. The most likely culprit was that one of our neighbors was burning/smoking/storing something, and every once in awhile, that something simply reeked. No matter. We’d light a candle and deal with it as best we could until the offensive odor dissipated. And after nearly a week of dealing with this on again/off again problem, it struck me.

This is either a dryer vent connection or a washing machine drain. It’s in the utility area mentioned earlier. And it’s not closed off. Which means it’s very likely that sewer gas is escaping through this opening, into our hallway, and then into our room. I know – it sounds disgusting. And it smells equally as bad. I did some research online, trying to figure out a way to cap the opening. I didn’t turn up anything useful. Jen and I took the above photo (on my iPhone) with us to a local big-box hardware store, along with some measurements of the offending opening. A nice guy, right at the entrance to the store, directed us to an aisle full of PVC pipes and related parts. After some looking around, we found what we thought would do the trick. A Fernco Quik Cap.
The plan seemed simple enough: Work the Qwik Cap into the opening of the drain/vent, maybe apply some caulk. Done. Well, it didn’t exactly go so easily. Before we left for the store, I had measured the opening and found it came out to four inches. And the Qwik Cap clearly shows its size as being four inches. But try as I might, I couldn’t get the Qwik Cap down into the opening. The cap was too big. I had a bright idea to cut some of the rubber off of one side, thinking that might alleviate the bowing effect that was keeping it from settling properly. But all I wound up doing was cutting myself (twice) and making a mess. A few more tries (and a couple bandages) later, I gave up. Out of curiosity, I searched out the Qwik Cap website. Imagine my surprise when I saw this image, and realized exactly how it is that these things are supposed to work. And when that little light bulb over my head illuminated, it gave me a couple more ideas: 1.) Get a smaller Qwik Cap, try same process over again. 2.) Insert a small piece of four-inch PVC pipe into the opening and then cap it with a new four-inch Qwik Cap. Ahh… possibilities.
Later in the day, we ventured once more to that big-box hardware place. This time, I brought along my tape measure so I could double-check the sizes of any potential parts purchases. We picked up a few different things; a PVC pipe with a cap, another (smaller) Qwik Cap, some adhesive and another thing that looked very promising. It’s an adjustable plug used for flow testing, and it’s specifically designed to close off drains, etc.
Once we got home, the adjustable plug was installed into the hell mouth. And after a few good turns of its knob, it’s now sitting snug and secure. As the problem with the errant sewer gas isn’t omnipresent, we’ll know in the next couple days whether or not the plug has done the job. Hopefully, it does. ‘Cause were getting tired of this shit.

This reminds of the time when I successfully replaced the flapper and handle on my rented toilet.
Boy, was I thrilled. And then the city slapped me with a zoning violation and made me tear the whole thing down.

The title is hilarious. Good luck getting rid of the smell! I hope it works.

wow your really been in the wars, sometimes its good to know a plumber, sounds like the stink pipe, keep us informed in how you got on with the fittings. Outside my bathroom they put the pipe and a screw cap so if theres any blockages they have easy access. Good luck Shawn

We were having a lot of trouble with the street sewer grates smelling like poo, even though they were just drainage sewers. It turns out some numbnuts in the neighborhood was emptying his Winnebago’s refuse tanks into the drainage sewers. Terrible for the environment and just a real swell thing to do.

That first photo is a dryer vent that shouldn’t stink at all. If it’s made of metal and has a seam along the length, this is the vent pipe outside. There should be a smaller PVC pipe in that closet higher up near the water supply – that’ll be the drain. If you don’t use it – the trap will dry up and allow sewer gas to enter your home. Cap it or dump a gallon of water down it every few weeks (or longer depending on the RelH)

Oh, yeah. It’s a dryer vent.
What’s up with that shit, Shawno?

We capped that vent, using the adjustable plug/tester/whatever. And we haven’t noticed the sewer-gas smell since. Go figure.

Well, everybody. The noxious sewer smell has returned. I’ve looked in the hallway, and there is (as BinarySpiral suggested) a plumbing connection that’s not capped. So that’ll be the next thing to close up.
