Toilets How-To Guides
View All →How to Fix a Running Toilet
Diagnose and fix a running toilet -- flapper replacement, fill valve swap, float adjustment, and overflow tube check -- with the dye test that tells you exactly what is wrong.
How to Unclog a Toilet
Clear a clogged toilet with a flange plunger, hot water and soap, or a toilet auger -- without cracking the porcelain or wrecking the wax ring.
How to Replace a Toilet
Remove an old toilet and install a new one -- drain, pull, set the wax ring, position the bowl, attach the tank, and test for leaks without cracking the porcelain.
Common Toilets Problems
View All →Toilet Keeps Running
One of the biggest water wasters in a home. Water flows continuously into the bowl or overflows inside the tank. Worn flapper, faulty fill valve, or float set too high. 200+ gallons per day wasted.
Toilet Won't Flush Properly
Weak flush, incomplete, or multiple flushes to clear? Tank water level too low, clogged rim holes, flapper closing too fast, or partial clog in the trap or drain.
Toilet Leaking at Base
Water pooling at the base usually means a failed wax ring. Left unaddressed: sewer gas in the home, subfloor rot, mold, and structural damage beneath the floor.
