Sudden drops in water pressure often indicate hidden leaks, corroded pipes, or slab leaks—especially common in older McKinney homes with galvanized plumbing.
Strange noises from your water heater signal sediment buildup, failing heating elements, or imminent tank failure—McKinney's hard water accelerates this wear.
Multiple slow drains or gurgling sounds indicate a main sewer line clog or tree root intrusion—common in McKinney's tree-lined neighborhoods like Historic Downtown.
Hot spots on concrete floors or unexplained water bills point to slab leaks—critical to catch early before foundation damage occurs.
A rotten egg smell indicates a gas leak (call immediately) or sewer gas escaping through dried P-traps or damaged vent pipes. Never ignore this odor.
Toilets that run constantly or faucets that won't stop dripping waste hundreds of gallons monthly and signal failing flappers, fill valves, or worn cartridges.

Their plumber explained everything, gave us upfront pricing, and even helped file our insurance claim. Absolutely the best plumber in McKinney."
