I am about to complete a re-roofing effort. I have about 6 roof vent pipes sticking out of the roof - I would like to get rid of them - if that is possible. Someone told me about Studor inline vents that can be placed in the attic, I would cut each vertical pipe in the attic near the roof and attach one of these inline vents per pipe. Once completed there would be no pipes sticking out of the roof.

Questions:

- Is this a good idea?
- Will I get noxious or smelly gases in the house?
- If this can be done, can a 1 1/2 inch Studor vent be placed on a 2 inch pipe?

Thank you in advance for your help.

Richard.

These are not code in my area...if your trying to hide the vents, offset them out of sight. erik

I don't recommend cheater vents. Plumbing systems produce methane gas,and I'm sure you don't want that floating around in your attic. Also VTR (vent thru roof) piping requires fresh air to get into the system. You may be breaking code like Erik said.

Thank you all for your replies. Besides your feedback, I did some more online investigation and the consensus is overwhelming that there is no substitute for the direct fresh air vents. Also as mentioned nasty gases can be realeased indoors.

This whole matter has come up as we are putting up an addition, including a totally new space for the kitchen. The new roofline over the kitchen sink is very visible from the back yard. I became very concerned when the vent pipe was put in, and made the new roof look horrible. The plumber put in a studor vent for the new kitchen sink only. I wanted to take it further and eliminate all vents prior to the new roof going on, also part of the work.

I will simply leave the vents alone, and go with that single one, which should be OK.

I have the vent at 88 inches off the floor, and will be putting an access panel in the upper shelf on the back of the cabinet that will be mounted on that wall. Hopefully it will not be an odor problem from up there, and I can access the unit in case of malfunction.

Thanks again...

Richard

I looked at the Studor web site and they claim that their product will not allow for methane gas or sewer gas to escape. Look at www.studor.com

A studor vent does not let gas out. That is is whole purpose. It lets needed air into the system but not gases out. I still would not recommend them except where there is no other choice like a kitchen island.

Check your local codes as these plastic check valve vents are not legal in most areas.....as for an "island-sink" Id install a loop vent. erik

OK, I'm not a plumber. Can someone please explain why the Studor AAV is not allowed by code? Is it because the product may fail? I read their site and the product seems so simple and useful. Also according to their information, their product is fail safe. (I know that they have to have a sales pitch). Has anyone ever had a problem with a AAV?

Studor vents are not against the codes, in the code book it is up to the plumbing inspector weather you can use the studor vents are not. I've been using them for years and never had a problem with them. They have really come in handy. I put a $2.00 studor vent in about 13 years ago and it has never been a problem. If you do start having a problem with it, all you have to do is unscrew it and replace it with a new one. Alot of plumbing inspector's, have old habits that are hard to break. The only problem is that you have to have space, where you can get to it, if you need to replace it, you don't want to put it inside a wall. I had a customer that a plumber did not vent his kitchen properly and his washing machine was sucking his kitchen p-trap dry, I put a studor vent under the sink, no more problems. Little bit late, but I was checking out the web-site.

Always check local codes before installing these vents....inspectors are more likely to approve these units in a remodel or retrofit when there is NO alternative. Im amazed when I see them installed in new contruction. erik
