We start every toilet installation by shutting off the water supply and removing the old fixture. We inspect the closet flange and wax ring seat for damage caused by repeated freeze-thaw cycles common in the humid subtropical climate with four distinct seasons. In neighborhoods such as Kentlands and Lakelands we check for cast-iron or PVC drain lines that may need adapters to satisfy current Montgomery County requirements before setting the new bowl.
Next we set a new wax ring and bolt the toilet to the flange with brass hardware. We use a level on the tank and bowl to prevent rocking that leads to leaks over time. Homes in Downtown Gaithersburg and Quince Orchard often have older slab foundations; we verify the subfloor is solid and add shims only when needed rather than forcing the fixture level.
After the bowl is secure we connect the supply line and install a new shutoff valve if the existing one shows corrosion. We run the fill valve and flapper through several cycles to confirm no seepage occurs at the tank bolts or base. Final cleanup includes removal of all debris and a check of nearby fixtures in Washingtonian Center and Montgomery Village homes to ensure water pressure remains balanced.
