How do I fix a blocked plumbing vent?

Answer by  eyeguy (3760)

A blocked plumbing vent is easily cleared by using an air compressor and a simple vacuum cleaner hose. Connect the compressor with a funnel and duct tape. Blowing out the obstruction only takes a few minutes

Ideally, you can go on the roof of the building and attempt to remove the blockage with a shop vacuum by way of the vent opening. If that doesn't work, you can attempt to use a pig-tail device to breakdown the blockage and then flush it out with water down into the outgoing sewer pipe.

It depends on where the blockage is. Some get good results using a long drain snake from the roof. Flushing the vent with a hose sometimes works, especially if you have a good idea where the blockage is and know it will not present a problem once it is flushed into the drain side of the system.

Well probley the easiest fastest way to do it is just cut it off and replace it with new pipe or fittings. All you really have to do is get a tee and attach it to the other pipe roun your new pvc through the roof and you should be good to go.

First you must find your vent; once you have found your vent you can use a plumber's snake to remove any debris that may be causing the blockage.

A blocked plumbing vent most times can only be repaired from on the roof where the vent sticks up. You'll need to obtain a long plumbing snake and run it as far as it will go down the pipe. Snakes can be rented from a local supply store.
