I have a shower drain that was snaked a few months ago and has started having a very light back up again. After maybe 5 seconds of unenthusiastic plunger work, it clears up just fine. But come back an hour later, run the water again, and it backs up again - even if no one has actually used the shower.

Draino and the like haven't resolved anything. We snaked a second shower at the same time, but haven't had a problem with it since then. No other drains seem to back up. We also got an external drain cover to capture more hair, etc after the snaking to try to keep the clogs down so I would hope it's not more hair.

So it's making me think maybe something with the waste line for this shower? Are there some ways to test this? If that is the problem, is there anything to be done without getting into the walls?

  • If plunging clears the drain for a time, but the clog returns later, I would perform repeated plunger operations and see if this would finally remove the clog. Alternatively, run a hose into the vent on the roof and see if this clears the drain. Aug 24 '18 at 14:23

One option is to get a camera or find a plumber who has a camera that can feed it into the drain to actually see what the issue is.

Another if you're concerned the problem is the vent is to go on the roof and snake the vent.

The issue could be anything from an object that went down the drain lodged in the pipe that the snake goes by without clearing to roots which will grow back over time.

It sounds like the original clog was only partially cleared and over the months it has accumulated enough hair/soap to become more blocked.

It's not unusual to have to snake a drain two or three times to get the pipes cleared. I would snake it again, this time being sure to really rotate the auger all through the pipe until it enters the 3" line (make sure your snake is long enough to do this).

Most plumbers have an inspection camera that can be inserted into the pipes in the same manner as a drain snake (minus the augering), although the fee for doing this is a bit high in my opinion. You can buy your own plumbing endoscope camera online for less. If you go the DIY inspection route, make sure you know how far it is from your shower drain to the larger 3" pipe and that the camera you select is made for plumbing inspection and has a long enough cable to cover this distance.
