I have an overflow box with two u tubes. When I 1st set it up over a month ago it was making all kinds of gurgling noises.
However I had the foresight to install valves on both of the drain lines right under the overflow so a simple turn of one of the valves and the problem was solved.
Now,after a month of quite,it's started making the noise again about every 30 seconds or so.
What could have changed to make it do this again out of the blue?
The water levels have all stayed the same.
I have an auto topoff in the fuge so it stays at a constant level.
I don't get it.
Any ideas?
