Toilet repair starts with isolating the water supply and removing the tank lid. I check the flapper seal, fill valve, and flush handle for wear. In homes built in Downtown Gaithersburg and Kentlands, older cast-iron flanges often show corrosion from four distinct seasons. I use a basin wrench and adjustable spanner to reach tight supply nuts without damaging tile. After part replacement I restore flow and verify no drips at the shutoff.
Montgomery County requires that any leak at the closet flange be corrected before finish work. In Lakelands and Washingtonian Center slab homes I often find wax rings compressed by seasonal humidity shifts. I scrape the old ring, clean the flange with a putty knife, and seat a new wax or rubber seal. The supply line gets replaced if the existing braided line shows kinks from repeated freeze-thaw cycles.
Quince Orchard and Montgomery Village split-level houses frequently have low-tank pressure from long horizontal runs. I measure static pressure at the shutoff and adjust the fill valve screw until the tank reaches the marked water line. Final checks include a ten-minute dye test and inspection of the base for moisture. All debris leaves the site before I close the door.
