The median Lone Tree home was built in 2004, from Carriage Club to RidgeGate and Lyric. Most of the plumbing here is newer, which means the problems are newer too.
Newer homes have their own issues
Builder-grade water heaters and fixtures from the 2000s are wearing out now. PEX systems are reliable, but the crimp fittings, expansion tanks, and pressure-reducing valves around them fail on their own timeline. A failed pressure-reducing valve is one of the most common causes of noisy pipes, dripping relief valves, and leaking toilets in newer houses.
Two water providers
West of I-25, Southgate delivers Denver Water's water, and Denver Water's drought rules apply. East of I-25, Parker Water & Sanitation District serves the area, with its own watering schedule. Hardness is similar on average, around 105 to 108 mg/L, but Parker Water's ranged from 34 to 206 mg/L in 2025.

- Water heater replacement and expansion tanks
