A few days ago I noticed that when my clothes washer tries to drain,
everything is fine for the first few seconds, but eventually a cup or
two of water squirts out the top of the pipe. It's obviously not
completely clogged, but simply draining too slow to keep up with the
water the machine is sending down the pipe. The toilet occasionally is
a little slow to drain also, requiring a second flush, but otherwise
everything else is and has been draining fine in the house.
I've tried auguring the drain pipe for the machine, without any
noticeable change, for about fifteen feet or so. I've also tried Zep
"Drain Care Build Up Remover", without any noticeable difference
Should I try Draino or some other product? I have a septic tank system
(recently pumped and in good health), so it would need to be safe for
Could this be a problem with the vent? The drain pipe does emit quite
a bit of gurgling sounds when I shut the machine off and let the pipe
play catch-up. I can hear gurgling for at least 15 seconds after the
water has made it's way down the pipe and out of sight, but I don't
know if that's unusual.
TIA for any ideas you might have.
