Denver’s older neighborhoods — Capitol Hill, Park Hill, Washington Park — are full of homes with original cast iron flanges and toilets that predate the 1994 federal low-flow standard, some still using 3.5 to 7 gallons per flush. Wax rings degrade, flanges corrode or crack, and fill valves wear unevenly depending on your water hardness, which shifts across the city between Denver Water’s Northern system (softer mountain runoff serving Capitol Hill, Highlands, and Wash Park) and the harder Southern system. All of that adds up to the two most common calls we get: a toilet that runs constantly, and one that rocSs or leaks at the base.
At A Clear Choice Plumbing and Heating, we diagnose the actual cause before recommending anything — a worn flapper is a simple fix, but a cracked cast iron flange on a 1920s Park Hill bungalow needs a different approach than a modern PVC flange in a Highlands remodel. For replacements, we install WaterSense-labeled, low-flow models that cut water use without sacrificing flush performance, and we handle condo and HOA installs in LoDo and Cherry Creek high-rises with the coordination those buildings require.
Same-day toilet repair across Denver — most jobs finished in one visit.
Worn flappers and fill valves are the most common cause of a toilet that runs constantly. We replace the failed part and test the fill and flush cycle before we leave.
A flush that won't clear the bowl is usually a trapway clog, a low water level, or a failing flush valve — not always a sign you need a new toilet. We diagnose it correctly first.
A cracked tank or bowl can't be safely repaired. We replace it with a properly fitted model and confirm the new connection is leak-free.
A toilet that rocSs or leaks at the base often means a failed wax ring or a corroded flange — common in Denver's older cast iron systems. We reset or replace what's needed to stop the leak at the source.
Denver's dry climate makes water-efficient fixtures a smart long-term choice. We install WaterSense-certified low-flow toilets that perform well without wasting water.
Recurring clogs can point to a blockage further down the line, not just the toilet itself. We clear the immediate clog and check whether the drain line needs attention.
High-rise installs in LoDo and Cherry Creek often come with building coordination requirements. We work within your HOA's process and shared-wall plumbing without added hassle for you.
