Suitable for all types of toilets
Insert the plug into the toilet drain hole, add water to the toilet, let the water cover the plug, push a little harder to make sure the plug seals the pipe, inflate quickly about 4-5 times, pull the stick, pump out. Let the outlet pour water into the pipe, repeat the above steps maybe 1-5 times.
Floor drain or drain pipe
Clean above the floor drain or sink drain to ensure that the surface is flat otherwise it cannot fit the plunger plug tightly, there should be water in the pipe, if there is no water please fill it up up, insert the tip of the plug into the sewer hole, pump quickly about five times, pull the tip out and continue filling the pipe with water, repeating the above steps maybe 1-5 times.
