My shower floods when I run the kitchen disposal...?

Question

I can't afford a plumber right now. So I need to figure out how to stop my shower from flooding when I run the disposal.

Answer 1

In order for it to do this the shower must be pretty close to the disposal.
You have a clogged line after the point where the two drain pipes come together. Since the shower is the lowest point in the system for something to come out it does so there. The clog is probably not bad enough to hold up the shower drain, but if you turned on all your faucets at once you would see the shower drain slow then start filling.
To cure this get a drain opener that is good for grease, since that is the most likely culprit comming from the kitchen.

Answer 2

The "Y" pipe in the drain, going to the sewer pipe has a plug, enough to send the water into the drain before going to the sewer line. You'll have to clear this line before it gets bad.

Answer 3

Get maximum strength Drano....keep using by following the directions until line is clear (water stops backing up)

Answer 4

try not to put so much down the disposal at one time
