How can you tell if a line from your septic system leading to your toilet is broken or damaged, we are getting

Question

frogs in the bowl.

Answer 1

Are u sure someone isnt playing a prank? or frogs dont enter the house/ bathroom anotherway other than the plumbing? Most/ all septic systems have a vent pipe as the main soil pipe leaves the house. Perhaps they can jump in that way if its not covered. Is it primary house or second home with low use and they grow there?

Lots of variables to examine.

Answer 2

1,  Frogs  CAN't LIVE IN SEPTIC TANKS.

2. The water in your toilet comes from the water supply, not the sewer.
