How to Blow out a Clogged Drain Using a Garden Hose


Any type of clog is an annoyance and a potential health hazard, depending on how much standing water is caused by the clog. Repair tools for clogs include a plunger, chemical drain openers, and plumber's snakes. However, a garden hose can accomplish a solid repair by creating pressure behind the clog which forces into the larger main drain pipes. The process of using a hose to blow out the clog simply requires sealing the impacted drains.

Things You'll Need

  • Water hose
  • Plastic materials
  • Duct tape
  • Press the water hose into the impacted pipe and stuff plastic around the opening. Seal the opening carefully with duct tape.

  • Close any drains that are present between the clog and the main drain. Stuff plastic into the drains and tape the plastic down.

  • Turn the water hose on and apply manual pressure the plastic seal. Monitor the other drains as pressure builds to look for water escaping. Continue to allow pressure to build until you feel the water pressure drop beneath the plastic seal.

  • Leave the water on for an additional few minutes to allow the clog to work through the main drain lines. Remove the plastic and tape from any sealed drains. Turn the water hose off and remove it from the pipe.

Tips & Warnings

  • The size of the clog may be too large for a water hose to force the clog through the pipes. A plumber's snake is the ideal tool for removing stubborn clogs as the tool will shred the clog as opposed to attempting to push it through the pipe. Using the water hose with a plastic seal is the same method as using a water bladder but cheaper. The key is to maintain manual pressure on the plastic seal to prevent air and water from leaking through.
