Sink or Tub Doesn’t Drain or Drains Slowly

A slow-draining tub or sink usually means the drain is clogged.

With a sink, first try using a plunger. If that doesn’t work, clean out the trap. While you’re at it, you may discover that it’s time to replace the trap. When reassembling the trap, be careful not to overtightened the slip-joint nuts.

A tub is often fouled with hair. Pull out the pop-up stopper (if the tub has one) by wiggling the lever and easing out the stopper. Remove the hair from the linkage. If this doesn’t entirely do the trick, use a blow bag or snake out the drain.

If you’ve taken the steps above and the drain is still slow, consider the vent line. Be sure it isn’t blocked with a bird’s nest or other debris. You can snake it from the roof, but be careful not to drop the snake into the pipe!
If you’re on a septic system, your tank and/or drain field may be overloaded. In this case, call a qualified plumber.
