Hello,
Just recently, when I get out of the shower, the water level in my toilet is right down & is making a 'glupping' sound. Probably air passing through the pipe down at the water level.
Then when I flush, it fills up to a high level! Before returning down to it's "too low" level so it can start it's glup'n again:p while I head off to bed:rolleyes:
In the morning I guess it's back up at the normal level..
Does it sound like I'm getting a blockage,
.. or has my shower & toilet started a relationship?:eek:

"has my shower & toilet started a relationship?"
They've always had one. Sounds lioke you have a blocked vent that need to be snaked and cleared. This can be done from the lavatory roof vemt. Put out enough cable to reach the base and 20 feet more. Good luck, Tom

Thank you. I want to say it becomes normal for the rest of the day.
I will see what cable we have. If it's too curly, I will get someone in to do it.
I will rate your answer well:)
