Answer:
No, it isn't normal to have to flush the toilet more than once to clear the bowl every time the toilet is used.
Please review the information below to ensure the toilet tank is emptying enough water to sufficiently clear the bowl with each flush.
- First, start by ensuring the supply valve is opened fully.
- Then, from inside the tank, make sure the refill tube is connected from the water control and inserted into the overflow tube without being kinked or damaged.
- Adjust the water level. It should be no lower than 1/2" below the top of the overflow tube. If it is lower than 1/2", raise the water level by turning the top screw on the water control counterclockwise. (You may need to flush after adjusting the screw to get the water level to rise.)
- Make sure the chain has only 1/4 inch of slack. (When you hit the trip lever, the arm should only move 1/4 inch before activation.)
- Use a mirror and a coat hanger or a 6/8 penny nail to clean out the holes under the rim (inside the bowl). Mineral deposits from water may cause the rim holes and jet hole to "shrink," which limits the flow of water.
- If there is a jet hole, use a screwdriver to clean it out. Important: Do not stick your finger in the jet hole.
- Reset the toilet with a new wax ring. You may need to consult a plumber to do so.
