Both of my toilets bubble when one is flushed! So,I just had the septic system cleaned out & a new pump put in. The house was built so that there are is an air trap/vent under the kitchen sink & in one bathroom. No vent for plumbing on the roof. I replaced the little screw on vents. Both of the toilets still bubble violently when either one is flushed! There is no septic smell to the air that comes out. I'm at wits end, perhaps one of those augers? Any ideas?

This is a venting problem
Remove the screw- on- vents to see if that fixes the bubbling... most likely it will ,as your vent is made to ''suck'' and not ''blow'' air---you will need to route the pipe to outside atmosphere for a permanent fix
Or unscrew the main cleanout plug that's outside(if there is one)and flush... see if that changes anything
An auger is the right approach,as there could be a block before the septic tank filling with water,not air and backing up into your toilet

I disagree! Sounds more like a blockage to me. Bubbles= a blockage while gurgles = a blocked vent.
The bubbles are caused by the discharge or flush hitting a partial clog and bouncing back sending a bubble of air ahead of it. The solution would be to snake the toilet drain lines. Good luck, Tom
