How A Plumbing
Vent Could Be Behind Your Clogged Toilet
While many quickly blame their toilet or the plumbing system for a clogged toilet, the culprit may be less obvious – the plumbing vent.
A plumbing vent allows air to enter the plumbing system and equalize pressure in the pipes. Without this air, water would not flow quickly, leading to slow or clogged drains.
A vent can be obstructed by an accumulation of leaves, debris, or a buildup of frost or snow, which disrupts the plumbing system's air pressure and creates a vacuum in the pipes.
So, when you flush the toilet, the water doesn't have enough force to move with the waste through the pipes, and it struggles against the vacuum effect, resulting in poor flushing.
