Clogged Drain Emergency: 5 Things NOT to Do (and What Works)
When a drain clogs at the worst moment, the instinct is to grab whatever is under the sink. Some of those choices make it worse.
Don't pour chemical drain cleaner
It corrodes pipes and seals, and if it does not work, the plumber has to deal with a sink full of caustic liquid.
Don't keep flushing an overflowing toilet
Turn the supply valve behind the toilet clockwise, then plunge.
Don't run the dishwasher or washing machine
They share drain lines and will push water back up into the sink or tub.
Don't use a coat hanger on the toilet
Porcelain scratches and the clog gets pushed deeper.
Don't ignore multiple clogs
That is a main line problem that can become a sewer backup.
What works
A flange plunger for toilets, a cup plunger for sinks, and a call to a clogged drain plumber. For recurring clogs we recommend professional drain cleaning or hydro jetting.
