Hello, for a VERY long time, all 3 of my toilets are clogging in concession. Once one clogs, I know that the other 2 are not far behind. This happens several times a month (sometimes all 3 clog a week). One toilet was replaced during a renovation, 3 flushes in and it too clogged. We have checked our vents & there are no obstructions & can hear the toilets when they flush.
Now I am being told to hire a company for $300.00 per toilet to run a camera down each to check for an obstruction.
Any other ideas? To me, this sounds like more than an obstruction.
Going off to plunge a toilet, yet again.
