What is that HORRIBLE SMELL? VACANT Home, or went on a VACATION?

What is that HORRIBLE SMELL?

Selling a home and have to leave it vacant? Going on an extended vacation? Have a rarely used sink, tub or toilet in your home?

Be aware that failure to run water down ALL of the drains can cause sewer or septic tank gas to invade your home.

It is caused by the water in the S traps and/or P traps evaporating enough that it siphoned out (breaking the seal) leaving the traps empty.

 p trap

Sewer gas odor comes from the decomposition of waste, and when the traps in your sinks, laundry, showers, toilets or floor drains dry out, (The water IS the seal) sewer or septic tank gas comes in.

This gas is combustible, contains methane and can make you sick!

This will emit sewer gas odor into the home.

If you have a vacant home for sale, be sure to run water down ALL the drains occasionally to replace the water in the trap that evaporated.

When going on extended vacations, have someone check in and run some water in all the drains. Also run water occasionally in a tub, sink, shower, or toilet that you rarely use. This will replace the water that has evaporated, and prevent sewer or septic tank gases from invading your home.

If it's too late, and your home is overwhelmed with THAT Horrible Smell...

OPEN ALL the DOORS and WINDOWS.
Place a FAN blowing the air outside.
Run water down the drain.
Add a deodorizer to the running water (Pine Sol, Mr. Clean, etc.)

Hope you found these tips helpful!

Cheryl, Good info. This is also very common in floor drains also. Like you I recommend running some water into seldom used traps.

Lorraine, Your Welcome! Happy Thanksgiving wishes for you too.

Donald, Thanks for commenting! Yes, I find floor drains and laundry tubs are the most frequent causes.

Sometimes Cheryl, that "awful smell" could be from the last Realtor who had the home listed... but had it way, waaaayyy overpriced... LOL.  Not a good plan.

Even though Thanksgiving is coming in a few days... it is never a good idea to have an "over-priced turkey" for a listing.  <dorky smile>

Cheryl - homes here in the desert suffer from the Bad Smell Syndrome very quickly.  The air here is so dry.  I have a lot of 2nd home owners who come in the winter.  oooh- oooh that smell!  I usually go over and run all the water, then pour a little Fabulouso down the drains and in the toilets for their welcome home.

Dear Cheryl,

Don't forget to remind folks of the drain under the washing machine as well. 
Unless the washer has actually "overflowed", the drain needs water added every so often.
The same p-trap situation exists there - not only when it is vacation-time - but even when at home!

Have a happy daay -
Lynn

Yep, I've smelled that smell! Sometimes it takes me a week to figure out that the basement floor drain is the culprit...

Cheryl -- excellent advice --- sometimes you go into a property and something is just a bit off (or is that off-putting).   It's a simple and very effective fix.

Karen, You're a Hoot! Yes but that is not only a bad smell, it also leaves a bad taste, and a whole lot of work for the next listing agent!

Andrea, Thank You for the nudge, I needed that. I'm glad you suggested I follow thru and post it.

Virginia, that's so nice of you, and I'm gonna check out that Fabulouso stuff, Pine Sol is a bit strong.

Lynn, That's the first time I ever came across that smell, It was from the Washing Machine drain, and took me awhile to find it. Great heads up! It is often the offender!

Tim, It's so odd that it's often difficult to pinpoint the source, but floor drains are another main offender for sure. I've spent quite awhile sometimes locating the source of the odor, especially if it just barely has evaporated.

Joni, Thank You! Your support is so appreciated, hope it helps some of the weekenders!

Mike, That's the best part! It's not very often that we can "FIX" something just by simply turning on the water.

THANK YOU all, for the comments and support! :)

What a great reminder and a good lesson for those who might not think of it. I'm going to go run some water down the sinks in the bathrooms I don't use often right now:) I'll also remind my clients!

Dawn, Now that you mention it, I've gotta do the same in the garage laundry sink. I ALWAYS forget that one is out there, as there is one in the laundry room in the house. It reminds me from time to time tho! LOL!

Hi Cheryl - This is great advice.  Occasionally when I am showing property I will pick up a smell, and to keep it from getting worse, I run a bit of water in the sinks.  Some listing agents don't seem to visit their vacant listings very often, which is a mistake because they might lose some offers from folks who are turned off by the smell.

This is very good advice especially for agents with vacant listings.

Susan and Kathy, Thank You. Yes, this happens ALL the time on vacant properties. As soon as you run water and fill the trap, it will STOP the odor from entering, then to remove it from the house, I open up everything and air it out.

That is a great advice, it is very important not to disconnect utilities during sale.

Thank you Inna, I do prefer to have them on, because you can then keep the home temperature comfy in the summer and avoid freezing pipes in the winter. Also easier to add water to all the drains, so you don't have to haul water in.
