Slow flushing toilet is a normal issue even you maintain it carefully. There are some reasons cause slow flushing toilet problem and they are always vary. From kids through paper towel into the bowls to some parts decay, all of them are the slow flushing toilet causes. However, according our yearly experience, four major causes to an improper flush. Knowing these causes can help us to avoid it happen and understand how to how to repair a slow flushing toilet.
1. The water level in the tank or bowl is not adequate:
It is commonly assumed that lowering the water level in the tank will save water consumption. This is a misconception. Increased water level increases the “Head Pressure” or flushing force required for the content of the bowl to empty. Decreasing the water level decreases the flushing power. Hence a second flush is needed. To ensure the highest amount of “Head Pressure” is achieved, the water level should be set one half inch below the top of the overflow pipe. This is achieved by adjusting the Fluidmaster 400 model fill valve to the proper height. Raising the height of the valve so that the C.L. (Critical Level) mark is one inch higher than the overflow pipe will allow for the tank to fill to the manufactures prescribed water line.
In addition to the water level in the tank, the water level in the bowl must also be at its maximum capacity. To determine the maximum capacity of the bowl, slowly pour one gallon of water into the bowl. Let the water in the bowl settle for 30 seconds. Note: Pouring the water too rapidly will cause the bowl to flush. Mark the water level in the bowl. A dry erase marker works well and wipes off easily. Flush the toilet. If the water level in the bowl does not refill to the mark you made, verify the refill hose is directing the flow of water into the overflow pipe and not back into the tank.
2. Incorrect flapper used or improper flapper setting:
Flapper selection and flapper timing is very important. Toilets made before 1994 must use a flapper that allows most of the water in the tank to flush out. These are typically called 3.5 or 5 gallon per flush (GPF) toilets. In the U.S.A., toilets made during or after 1994 require flappers that only let a limited portion of the water flush out of the tank. These are 1.6 and 1.28 gallon per flush toilets and referred to as High Efficiency Toilets (HET).
Using a flapper that is intended for 1.6 or 1.28 GPF toilets in a 3.5 or 5 GPF toilet will not allow enough water to exitfall out of the tank andto create a powerful flush. Flappers intended for 1.28 and 1.6 GPF toilets are usually equipped with a timing adjustment that allows the consumer to adjust how long the flapper stays open. If the timing adjustmentflapper is improperly set, the flapper may close too soon and not allow enough water to exitfall out of the tank or not give the bowl enough time to refill to the proper level due to the tank refilling quickly.
3. The flow path from the tank to bowl is clogged:
If the rim feed holes become clogged with mineral deposits or the jet hole becomes clogged with minerals and/or waste the flush will become week. Use a wire hanger to clear the rim feed holes located under the rim of the toilet bowl. A wire hanger can also be used to removefish large waste from the jet hole usually found at the bottom of the toilet bowl.
4. The Drain or Trap way is clogged:
To determine if the trap or drain is clogged, rapidly pour one gallon of water into the toilet bowl. If the water level in the bowl rises quickly and slowly drops or does not drop at all, there is a clog. Try plunging the toilet. If plunging does not help, use a toilet auger to clear the trap and drain.
how to fix a slow flushing toilet is not as difficult as you think. If that does not correct the problem, contact a plumber.
