Step 6 · Reinstall Toilet and Final Test
Once the clog has been cleared from either the drain or the vent, you must reinstall the toilet. Begin by using a putty knife to scrape all the old wax off the flange on the floor and the bottom of the toilet. Place a new wax ring directly on the flange, centered over the drain opening. Carefully lift the toilet and align the holes in its base with the closet bolts sticking up from the floor. Lower the toilet straight down onto the ring and press down firmly to create a seal. Reinstall the washers and nuts on the closet bolts and tighten them alternately, being careful not to overtighten and crack the porcelain base. Reconnect the water supply line to the tank. Turn the water supply valve back on and allow the tank to fill. Flush the toilet and run water in the other fixtures to confirm that the gurgling noise is completely gone.
