    We have a basement shower which was first used today. The shower drain, sink, and toilet pipes were put in 4 years ago and we just finished the bathroom about 2 months ago. We have been using the toilet and sink with no problems for 2 months. I went into the storage area soon after the first shower and see the basement floor drain backed up with an inch or so water in about a 3 feet ring. My son noted during the shower he heard gurgling sounds and the water would backup in the shower a little bit and then "whoosh" out of the shower. This gurgling and whooshing only lasted a few minutes and the rest of his shower was normal. I checked other toilets/showers/sinks and even ran the culprit shower again and the water does not come up as I watch the floor drain. I poured water into the floor drain and the water level about 6-8 inches down stays constant. I'm obviously not a plumber but think the line was likely dry and the new water source might have caused some type of acute venting problem? Any ideas are much appreciated. Thanks, Dave

    There are many possibilities, but it could have had paper stuffed into it to keep odors out. It would then cause a backup until it got wet and the water flushed it out. Until it happens again, there is no real way to diagnose it.

    I'm betting on paper or a rag stuffed down the pipe too

    Thanks for the replies. Just ran the dishwasher and there is water around the basement drain again. So I guess there is a clog somewhere in the line.
