Fixing a toilet often starts with identifying the issue. Common problems include a running toilet, weak flush, clog, or leaks. If the toilet is running continuously, the flapper valve inside the tank may be worn out or not sealing properly. Replacing the flapper is a simple fix—turn off the water supply, drain the tank, disconnect the old flapper, and attach a new one. If the flush is weak, check the water level in the tank and adjust the fill valve to ensure it’s at the proper height, usually marked on the overflow tube.
For a clogged toilet, a plunger is the first tool to try. Use a flange plunger for the best seal, and push firmly but steadily to dislodge the blockage. If plunging doesn’t work, a toilet auger (or closet auger) can reach deeper into the drain to break up or retrieve the clog. Avoid using chemical drain cleaners, as they can damage pipes. If leaks are present, check the connections at the base of the toilet and around the tank. Tightening bolts or replacing the wax ring under the toilet may be necessary for floor leaks. If the toilet tank isn’t filling properly, inspect the fill valve and float mechanism. Older toilets may have a ballcock-style fill valve, while newer ones have a vertical fill valve. Adjusting the float arm or cleaning mineral deposits from the valve can often restore proper function. If the fill valve is faulty, replacing it is straightforward—shut off the water, drain the tank, disconnect the supply line, and install the new valve according to the manufacturer’s instructions. For persistent issues like cracks in the tank or bowl, replacement may be the only solution. Always turn off the water supply before attempting repairs and have towels or a bucket handy for spills. If you’re unsure about any step, consulting a professional plumber is a good idea. Regular maintenance, such as checking for leaks and cleaning components, can prevent many common toilet problems and extend its lifespan. With the right tools and patience, most toilet repairs can be done without costly service calls.
