View Full Version : How do I get past T pipe when snaking a drain?

Aug 27, 2010, 07:49 PM
I've searched a bit and haven't seen a question/answer for this, so if there is one please kick me in the right direction!

We have a free standing shower and separate bathtub next to it. The shower drain is backing up and slow to drain... the bathtub drain is not. The shower does not have an overflow pipe, so as far as I know I have to go down the shower drain to find the clog.

I've plunged the drain (pretty good suction with my plunger), and it forces the water down but fills right back up with the standing water in the shower and does not have much effect. I've also used Drano which also didn't work like it has in the past.

I bought a 15' auger and started threading it down the drain. The problem I am running into is that a few inches past the water in the pipe, the snake doesn't go any further (I can see about a foot down the drain, with water at the last inch I can see). I've turned the snake, shaken it, wiggled it... to no avail. I assume the shower drain is connected to a T or L pipe and that's why it won't go further. Are there any tricks to threading the snake past this point?

Thank you!

What you are running into is the trap for the shower. Sometimes it can be difficult to get the snake to go through the trap. What kind of snake do you have?

Here's a link to what I have - it's 25', not 15' like I originally said:

Should be able to get that to go through. When you hit the trap you should have about six inches of snake between the drain and the drum. Tighten the thumb screw to lock the snake in place in the drum. Then you can push and turn the snake at the same times. Then loosen the screw and pull a few more inches of snake out and repeat. Keep feeding the snake out a few inches at the time until you have made the turn.

As Harold said, most likely you're running into the PTRAP. Tighten the thumb screw and then try to turn and push the snake as it is turning. If that won't work then have a friend turn the snake while you force the snake past the trap using two hands... that will definitely get you past the trap.
