We have moved into an old 1945 home. Our main water room is on a septic tank, which we just had cleaned. Our problem is our toilet does not flush. Water just seems to drain slowly. I have pulled the toilet and checked the main pipe - all is clear. Why does the toilet not flush.

There are many reasons a toilet does not flush right. Here are some ideas to try. First pour 2 and one half gallons of water into the toilet bowl and see if the toilet flushes properly. If it does, then there is nothing wrong with the trap of the toilet or the vent. This means its a problem with the tank to bowl. In the tank the water level has to be just right for a toilet to flush. It should sit one inch below the top of the overflow tube inside the tank. The ball **** (fill valve) should be depositing water into the overflow tube through a small brass or plastic tube from the top of the ball **** . If it is not, then the bowl is not refilling after the flush, and there will not be enough water in the bowl to flush. In addition, check to see if the flapper is closing too fast after you pull the handle. The flapper should remain afloat until almost all the water empties from the tank. If it shuts too soon, the toilet will not flush. One more thing, watch how fast the water leaves the tank. It should take no more than a few seconds to empty. Many times the jets under the rim of the toilet seat get clogged and the water will not enter the bowl fast enough to cause a flush. The jets can be cleaned with a coat hanger. But if you clean them with a coat hanger and they still flow slowly, it could be there is something blocking the water from entering the rim. Alot of times tank cleaning bricks and blue water parts get flushed into the rim of the toilet and do not allow the water to flow into the rim at the proper speed.
Now for the bowl. If the toilet does not flush when you pour your water into the bowl, there is probably a problem with the trap or the vent of the toilet. Since you must first displace the air inside the sewer line when you pour a gallon of water into it, if the vent is clogged, the toilet will have a problem flushing. If the trap is clogged the toilet will not flush properly.
If the toilet is the problem, replace it with a Kohler Wellworth.
