Can anyone please advise me before i start worrying... (more). Just moved into a rental property with a septic tank. I have just been down there and it's making a bubbling/gurgling noise. Google tells me its either full or blocked... estate agents are closed, I'm pretty sure it's our responsibility to sort it out. But looking to find out if this is a problem or if it's normal
I called someone who fits them and he said it might be normal god the tanks.
How.often do they generally need to be emptied?
