plumbing vent problems

[Suzann Swain]

I have a complicated problem - one of which I have spent around $300 on and still not solved. We bought this mobile home in 95 brand new. From the time we bought it the washing machine water backed up in our kitchen sink (about 5inches ) and even overflowed from the vented pipe underneath the cabinet. When we moved our home 4 years ago we put in a new pipe and ran our washing machine line out back - problem solved. In '02 I started noticing the commode gurgling up in the bathtub when flushed. Called a reputable place (that also installed my septic system). They snaked the main line, and all the lines inside, vent on top of roof and no blockage found. It was found to be a venting problem so they loosened the seal on the vent under my tub and the problem was solved, or so I thought. About 6 mths later, a smell started arising everytime I used the kitchen " sink/dishwasher - defininitely a "poop" smell under the bathtub. I changed out the vent with a new one and the old problem started again only this time when water is let out of tub, shower makes a horrible sound. The drains all drain fine - no sluggishness. A plumber came a week ago and put in a second vent under the tub thinking this would help. Well now the smell comes under my bathroom sink (but not as bad) and the shower drain has a horrible racket when water is let out of the tub and also it sucks alot of water from the commode when it drains - I'm at my wits end with this and do not want to continue spending money with no results - please help if you can. Sick and tired Suzann.

It sounds like the manufacturer fogot to put in a through the roof vent when the home was being built.
Somewhere in your installation / set up papers, you were suppied with a drain line print. if you can find that, it will show how many vents through the roof you should have.
If you don;t have the print, contact the manufacturer and ask for it. they have to send it to you. it is one of the federal regulations.
It is too bad that you had so many people monkey with the drain lines, or you could have pinned this back on the manufacturer.

Thanks for replying Eugene. Now when you say a through the roof vent do you mean like the ones above the bathrooms where the commodes are? The plumber said I may have to vent the shower if it is not vented but I dont want to go to the expense of another service call - would the manufacturer know if there is a shower vent?? I don't think they make North River homes anymore - I couldn't find a drain line description in my paper work. I'm gonna call the place where we bought it and see if they can give me a number or something. I'm so tired of fooling around with this but I can't stand having a sewer smell or hearing an explosion every time we bathe. Thanks for replying and please respond if you know anymore helpful hints.
