Leaking tile floor shower drain
Hi, The water backed up and we used a plunger thinking the drain was plugged up. It drained, but shortly water started to leak from the down stairs ceiling. The drain is plastic in a 20 year old house. I have been told that a rubber coupling was blown apart when we used the plunger. I was shocked to hear that there is a rubber coupling that would not withstand the low pressure applied by the plunger. Could I have ruptured a plastic pipe of blown apart a bad joint? How do I proceed to find out what the problem is? I guess cut out the ceiling below the shower?
