We don't know when this started but they noticed it the last time we did a septic clean out. There a very slow but steady stream of water coming from the house and if we open the cover on the pipe that runs to the septic system we can see it there.
No sinks are leaking and we put food coloring in the tanks of all the toilets but after 2 hours there's still none in the bowls. Verified that there are no leaks going down the drain in the boiler room, no showers or baths are leaking either.
Any thoughts of what else it could be?
Thanks in advance.
