Check for leaks at the toilet’s hydrostatic connections by pressurizing the tank and inspecting every connection point closely.

Start by shutting off the water supply and removing the tank lid so you can see inside. Turn the supply back on slowly to fill the tank and watch the water level; a rapid rise combined with dripping at tank bolts or the fill valve indicates a leak. Gently apply a dry paper towel or cloth around each connection including the fill valve base, flush valve flange, and tank-to-bowl gasket while the tank is full; any wetting shows the leak location. For threaded shanks, hand tighten then add a quarter turn with a wrench while holding the mating piece to avoid twisting the tank or cracking porcelain. If you see seepage around bolt heads or base gaskets, drain the tank, remove the bolt and washer assembly, replace the rubber washers with new ones sized for the model, and hand tighten evenly to avoid deforming the gasket. After reassembly, refill the tank and perform three consecutive full flushes while observing connections to confirm the repair under dynamic pressure.

Common mistakes include assuming a slow drip is just condensation and not a leak, which you can avoid by using a dry cloth test to localize moisture. People often overtighten bolts which cracks porcelain or compresses gaskets so always tighten evenly and stop when the washer seals snugly. Another frequent issue is not testing after the first flushes; some leaks only show under the transient pressure of an initial flush so run multiple full flushes and recheck all seals; if persistent seepage remains, replace the entire tank-to-bowl gasket assembly rather than repeatedly tightening fasteners.
