    Default design proposal

    Hello all,

    I am just brain-storming about design ideas. One thought that I have is to fix the problem of when a main sewer gets backed up and ends up pouring sewage out the first fixture in the house. Couldn't a drain (that is not part of a fixture) be installed just for this purpose to catch everything in case of a backup in the main?

    Have you ever seen the show "Dirty Jobs" episode dealing with the toilet back-up in Queens, NY?

    They do make check valves for this, but I'm not sure how well they work and how many problems by themselves that they might introduce.

    You could use a backwater valve. These are required for the sanitary side on buildings in/below the floodplain in this area. This will only benefit you if it's the main sewer (outside of the structure). Won't help you if it's your fixtures backing up but it will/can keep the sewer from the city side backing up in your house.

    A floor drain? Where would it drain to?

    Default drain

    It would be a good idea but where would it drain to. If it connected to the backed up sewer, then the water would come out of it before it got to the "first fixture", which is not necessarily where the water would come out anyway. The water comes out of the "lowest fixture".

    Even if it were a barrel with a 50+ gal. capacity. It would stop the nasty mess that so often occurs at the first fixture. Just brainstorming here.

    My point was really that it's better to prevent the backflow than to try to handle it.

    Default backflow

    You were not listening. It does not necessarily occur at the "first fixture" it occurs at the lowest fixture, and you don't seem to understand how little 50 gallons really is when a sewer starts to back up. And when the backup is repaired, what are you going to do with the water in the barrel? Prevention, and a backwater valve is not a panacea, is better than coping with the symptoms.

    LOwest fixture.. understood. yes, 50gal aint much. But it sounds like the backwater valves aren't a great solution either. What is the best way (other than the obvious no big things down the drain) to handle a backup and avoid it coming into the home?

    I agree ...backflow preventers do work... if the sewers overflow any more than the preventers can handle then the whole floor and the lawn is going to be covered with sewerage.

    Ok thanks guys,

    I have never seen a backflow preventer. Can they cause problems with catching waste and causing clogs?
