Step 4 · Attempt to Clear with Water

The first method for clearing a deeper clog is to use water pressure. Have your spotter turn on the water to a garden hose that you've brought up to the roof. Use a high-pressure spray nozzle to direct a powerful jet of water down into the vent pipe. Apply the water in short bursts of 10-15 seconds. Have a helper inside the house listen for water flowing through the pipes and check if the gurgling sounds diminish or if drains begin to flow better. If the water starts to back up and overflow the vent pipe, stop immediately, as this indicates a severe blockage.
