Mysterious sounds in the sewer

Good morning,

for 3 days our sewage system has been making some strange noises. You know that bubbling sound in the pipe. What could be wrong with it? And especially, how do I get rid of this annoying bubbling??
I would appreciate any help...

Best regards
Ursula

Hello Ursula,

I have heard this problem quite often. Such gurgling can really be annoying...Try the ventilation system and have it checked out...Maybe something has accumulated there that shouldn't be...
Have fun with it!!
Best regards, Uschi

OK thanks then I will tackle it....Let's see what comes of it....Thanks already....

Where can you hear the bubbling? In the sewer? In the drain (sink etc.)? Heater? That would be important information ;-)
