Older home, single-level built in the 70's.
Had plumbing updates such as a shower added to a half-bath back in the summer, with no problems until now.
Recently, loud bubbling noises began in the 2 toilets, with no clothes or dish-washing activity.
One night, clear clean water puddled around the base of one of the toilets, rather than overflowing the bowl. Cleaned it up, no further incidents for a few days.
Then, while doing laundry, an increased amount of bubbling noises and clear, clean water reappeared at the base of the same toilet, plus more clear, clean water backed up into the bathtub and shower stall at the same time, but drained away on their own.
We stopped doing laundry for 4 to 5 days and both toilets flushed normally with no leakage. We decided to risk a load of laundry.
This time clean soapy water leaked under the washing machine and brown sludgy water backed up into the shower stall and bathtub, and brown water leaked from the base of the same toilet. Both toilets seem to flush normally after a few hours of solitude unless water has been flowing recently in a kitchen or lavatory sink.
Then they can be difficult if not impossible to totally flush the residue. What is the most cost-effective & logical method to troubleshoot this situation prior to calling in a pro?
