Vent down instead of up?
One of our kitchen sinks has a vent problem , I think it is connected
to a vertcial vent that exits via the roof. However, the set up is with a double sink connected to a common U trap. One sink has a disposal. If the other sink's drain is sealed then the water does not flow out of the disposal sink. Once you unseal the other sink all is well. Also this sink sometimes gets an awful sewer like smell. I clean the disposal regularilly with bleach so it is not this. I wondered if I could put a seperate vent to this system , but I cannot go up . Would it be OK if I went down after making a U above the sink pipes, I have plenty of space under the house, but it would be difficult ( lots of walls to cut into ! ) to go up. If you have any ideas please cc my email so I don't miss your great thoughts. |

There is another thread about vents just in the past two days or so: Path: border1.nntp.dca.giganews.com!border2.nntp.dca.gig anews.com!nntp.giganews.com!atl-c08.usenetserver.com!news.usenetserver.com!pc02.us enetserver.com!fe07.usenetserver.com.POSTED!78cde7 79!not-for-mail Newsgroups: alt.home.repair From: Ignoramus26172 Subject: Bad smell from utility sink.

Or you can use groups.google . Anyhow, I think you should unclog the current vent. Was your house built by madmen? If not, theywould have put in a vent for every sink, tub, and toilet. It sounds like yours is plugged, and it's using the other half of the sink to get started. however, another symptom of a clogged vent is that it siphons the water out of your pipe, emptying the trap, and that's why you smell sewer gas. |

Most vents go up, There is a loop vent for Island. Put if your getting sewer odor your trap is dry . Both sinks go into the trap right? |

Thanks I did try putting ahose down the vent and it flowed OK .. did
not change the problem. The smell part ( in reply ) that it might be caused by a blocked vent has me wondering if the vent actually connects to anything! It might just be emptying into the ground under the house. It is not a nic ething to go under house so i have put this off for now.. Seems I am not alone with this problem so i will welcome more ideas. |

Was the builder a crackpot? Why would he put in a pipe that only had to go to the top floor and connect to a toilet or sink drain and run it all the way to the basement? Or a later owner: If the pipe connected to the drain pipe as intended, why would someone later disconnect it? If that's not what you mean, you've lost me. I think I worked on a house with Habitat for Humanity one day that had a vent that stopped in the middle of the house, but that was after earlier people had torn out the wall and torn out part of the pipe. It is not a nic ething to go under house so i have put this off for now.. Seems I am not alone with this problem so i will welcome more ideas. |

It was connected as intended and the vent pipe somehow came off. That would make it less likely critters coudl go in at the top and reach the part of the vent still connected to the drain. IOW, ISTM it would make it less likely that the vent would be clogged since the vent would be shorter, only from the connection place to wherever the break in the vent pipe was. It doesn't have to vent out the roof, only some place higher than the highest trap, which would be a bathroom sink most of the time. And if it were broken and displaced, pouring water in from the top like you say you did above iiuc, would have led to water whereever the vent pipe was broken and below, not necessarily all in the basement. Any sign of that on the first floor? Do vent pipes ever get broken? |
