This post will help you identify some possible reasons for your toilet’s poor performance.
If the slow flushing toilet is on the ground floor, run water from a fixture higher than the toilet. Perhaps a tub on the second floor or a sink in the same restroom. Watch the toilet bowl. If you notice turbulence, if the water line appears to be getting higher or if you notice air bubbling, your sewer may be the culprit.
When the main sewer line to the building is becoming clogged or slow to drain, it will reveal itself in the way the toilet flushes. If you notice any of the fore – mentioned signs, don’t wait for the toilet to begin flushing normally. Slow running sewer lines normally get worse with use. Waiting could mean while you are using water in a different part of the house, your sewer is backing up in the basement or wherever the lowest point of drainage in your house is.
If you don’t notice any of the above mentioned signs, your situation is not as bad as you may think.
You may be able to resolve a slow flushing toilet yourself.
Remove the tank lid and look for a stain created by normal water level on the side wall of the inside of the toilet tank. If the water level is lower than the staining, the flapper on the flush valve may not be creating a perfect seal. Energy and resource conservation studies have revealed a need for at least 1.6 gallons per flush for a toilet to effectively flush waste out of a toilet and provide enough flow in the sewer to disperse solids. This has become the standard for water consumption for water closets since September 14, 1998. Beware the plumber who advises use of bricks or filled jugs in the toilet tank. Water conservation is already at its lowest point. Using less water to flush the toilet only creates the potential for main sewer line backups.
If water is at the water line in the toilet tank, there may be a restriction in the main jet at the bottom of the toilet bowl. Or, calcium and mineral buildup in the jets at the rim of the bowl may be inhibiting the delivery of water to the bowl once the main jet has begun pushing water through the trap. The main jet begins the vortex action which creates a siphoning effect. The jets at the rim allow for the bowl to wash out as well as to supply the bowl with water until the siphoning has finished flushing waste from the toilet to the sewer.
Cleaning the jets can be accomplished by using a calcium and lime removing solution like CLR or a home made solution of baking soda and vinegar. Here is what you can do…
- Mix the baking soda and vinegar.
- Then empty the water from the toilet bowl.
- Put a large sponge into a plastic bag that will not pleat itself too much by stuffing the bag and sponge into the trap mouth of the toilet. Take action to ensure the sponge and bag will not move through the trap of the toilet into the sewer. You are only using the bag and sponge as a plug that will need to be removed in a few hours.
- Fill the bowl to the rim with the solution of vinegar and baking soda and allow the jets to soak for a few hours. Over night if possible.
- Next, use a funnel to poor vinegar (only) into the overflow tube from inside the toilet tank. The vinegar will sit in the rim and soften calcium or mineral buildup at the rim jets from inside the rim.
- When you have allowed it to sit for at least a few hours, pull the plug and allow the toilet to drain. Use a blunt object and an inspection mirror to dislodge the softened mineral buildup at the rim jets and the main jet.
- Fill the tank with water and flush the toilet a few times.
(If you use CLR, be sure to place plastic wrap over the bowl and the overflow tube. Tape the plastic wrap to ensure fumes do not escape. Also, CLR and Vinegar is very bad for septic system households. If this is the case. You may decide to take your chances with chemicals. However, you may also try to clear the jets beneath the toilet rim with a piece of mechanical wire. You will need a small mirror in order to see where the jets are.)
