How come when I flush the toilet the sink flushes?

     The other day I did an inspection for a renter that was considering buying the home they were renting.  I have done a few of these before and find it Old  fashioned toilet from 1902often helpful having the tenant being there as they can often provide “perspective” on concerns that I otherwise might not be able to get additional information about.

     One of their concerns was that whenever they flushed the master bathroom toilet---not only did the toilet make a lot of noise when flushed, but the water siphoned out of the sink and shower traps----or tried to anyway. 

     I said I would check it out and suspected some sort of venting issue.

All tied together with no place to go     In talking to the seller, they echoed the tenants concerns and stated that it had always been that way----since it was built three years ago.

     When I inspected the attic this is what I found.

     Instead of the vents going through the roof all three vents were tied together and capped off.  As a result, when the toilet was flushed, it was attempting to “vent” through the sink drain and the shower drain resulting in the siphoning.

     One of the parties asked me how this could have ever pasted the city inspection.  I simply said that it would be unusual for a city inspector to go in the attic, and added that this is just one of the many examples of why I have a job.

Seriously?  Who does that!?  Does that mean that if the tub overflows, the toilet will to?? :)

Charles, Isn’t that interesting. Cities charge for permit fees and inspections and yet do not fully perform what needs to be done in order to have the building permit actually mean anything. Inspections are so important I actually will not represent a client who does not agree to get one!

Just to much trouble to cut a hole in the roof, maybe the roofer was supposed to do that part.

Posted by Dennis Chamberlain, Eastern WA Home Inspections (Eastern WA Home Inspections, LLC) almost 2 years ago

Lori, fortunately not a very difficult fix

Michael, no---just a siphoning issue

Kathleen, the permit fees are so small they could never possibly be sufficient to properly inspect everything.

Dennis----it was probably raining on that day:)

I don't understand how this person got away with doing a job like this. Kudos to the renter by having had an inspection performed on this property.

at least this appears to be a fairly inexpensive fix.... but geeeeeeze!

I had this happen the other day in a public bathroom. I went out and told the receptionist and she asked if she looked like a plumber...

Posted by Paul Henderson, Broker, Realtor® Tacoma,Gig Harbor,DuPont,HartstenePointe (RE/MAX Professionals & Four Seasons Inc.) almost 2 years ago

Kymberly, this was most likely the easiest way for the plumber to put the system under test for leaks----they just forgot to go back and un-cap it and run it through the roof

Alan---very easy

Paul, so did she look like a plumber? :)

Another successful inspection - you must be flushed with success.  But I am just venting.

Posted by Gene Riemenschneider East Contra Costa Home Sales 01492725 (Home Point Real Estate) almost 2 years ago

Gene, and I am completely drained reading your post----could just be a pipe dream though

Posted by Charles Buell, Seattle Home Inspector (Charles Buell Inspections.com) almost 2 years ago

Or why don't they just... Well now, I probably shouldn't be venting my crappy alternative on your post. Yes, just flush that idea away.

Charles - Job security.  Just remember, you'd have to get a "real" job if builders, flippers, remodelers, and "handymen" knew what they were doing?

Posted by John Mulkey, Housing Guru (TheHousingGuru.com) almost 2 years ago

Kate, all flushed----only clogged a little

John, I have suceeded in avoiding having a "real" job my whole life :)

Posted by Charles Buell, Seattle Home Inspector (Charles Buell Inspections.com) almost 2 years ago

CB, there are so many ways to discuss this. But alas, I must pass. heheh

Posted by Ask Kate for answers (Get-Your-Best-Mortgage-Rate.com) almost 2 years ago

Sure seems like a draining experience.  I'm attending a Home Inspect tomorrow and hopefully all will flow well.

C'mon!  That keeps the sewer gas out of the attic!

By the way, at the one placed I lived in South America that had an indoor toilet, it looked just like that (sans the toilet seat - they don't use toilet seats there)!  We, however, had to fill the tank with water from the creek nearby...  only then would it flush!

Posted by Jay Markanich - Northern VA Home Inspector (Jay Markanich Real Estate Inspections, LLC) almost 2 years ago

Kate, Steve "passes" all the time----hard to take:)

Sue, may the flow be with you

Jay, but if we let sewer gases into the attic then I have to put up a no smoking sign!

Posted by Charles Buell, Seattle Home Inspector (Charles Buell Inspections.com) almost 2 years ago

I wonder who the installer was, must have been his first day on the job.

Posted by CARL & CEIL WINTERS Canyon Lake/New Braunfels /San Antonio (Complete Inspection Service) almost 2 years ago

Mr Charles,

That is often caused when a rat is caught in the sewer vent pipe. Probably your problem there.

Carl and Ceil, see my comment to Kimberly in comment #9

Nutsy, in this case I am pretty sure it was a squirrel aka pipe cleaner.

Posted by Charles Buell, Seattle Home Inspector (Charles Buell Inspections.com) almost 2 years ago

Nah, in a few years that methane turns to CO2 and it's nonflammable!  Of course, there's attic venting I suspect!

Posted by Jay Markanich - Northern VA Home Inspector (Jay Markanich Real Estate Inspections, LLC) almost 2 years ago

Mr Charles,

A proper attic inspection would have found that problem quickly. I hope you know that.

Great post as usual! That's very bad, but any easy fix!

Thanks for sharing,

As we well know most city inspectors do not carry ladders. Hard to get up in an attic without one.

Posted by James Quarello - Connecticut Home Inspector (JRV Home Inspection Services, LLC) almost 2 years ago

Jay, there is even me venting

Nutsy, really?

Adam, thanks for stopping by

James, some jurisdictions get around that by requiring that the builder "provide access" to all areas that need inspecting----no ladder in place----no look.

Posted by Charles Buell, Seattle Home Inspector (Charles Buell Inspections.com) almost 2 years ago

Is there any roof ventilation ?  I noticed the dark color of the rafters and skip sheathing; primarily towards the rear left in the photo.

That toilet looks like it should be in a musuem !

 

Posted by Kevin Hergert (Hergert Inspection LLC) almost 2 years ago

Kevin, just old wood in the shadows----ventilation was fine.

Posted by Charles Buell, Seattle Home Inspector (Charles Buell Inspections.com) almost 2 years ago

They were going to come back and finish the job. Someday!

Posted by Troy Pappas - Virginia Beach Home Inspector (Safe House Property Inspections) almost 2 years ago

Troy, yup----pretty easy to forget

Posted by Charles Buell, Seattle Home Inspector (Charles Buell Inspections.com) almost 2 years ago

Charles,

Great Find! Plumbing always seems to get some funky work.

Love the old Water Closet shot.
