Water is essential for everyday life in your Kent, WA home, but if your water quality isn’t ideal, it can quietly damage the appliances you rely on most. From dishwashers to water heaters, washing machines to refrigerators, the effects of poor water quality can result in shortened lifespans, costly repairs, and lower performance.
At CPR Rooter, we’ve seen the impact firsthand. This guide explains how different water quality issues affect appliances and what Kent homeowners can do to prevent long-term damage and protect their investment.
Common Water Quality Problems in Kent
While Kent’s municipal water is treated and monitored for safety, that doesn’t mean it’s perfect for your appliances. Common water quality issues include:
- Hard Water: Contains high levels of calcium and magnesium, which lead to mineral buildup.
- Sediment: Rust, sand, and other particulates that can clog filters and valves.
- Chlorine/Chloramine: Chemical disinfectants that degrade rubber seals and gaskets.
- Low pH or acidic water: Can corrode metal parts and internal components.
These invisible issues lead to very real problems over time.
Water Heaters
Effect: Hard water causes mineral scale to collect at the bottom of tank water heaters or around the heating elements in electric units. This forces the unit to work harder, raising energy bills and increasing the risk of breakdown.
Signs of damage:
- Rumbling or popping noises
- Reduced hot water supply
- Rising energy costs
- Shortened unit lifespan
Solution: Install a water softener and flush the tank annually. CPR Rooter can provide both services.
Dishwashers
Effect: Mineral deposits clog spray arms, filters, and valves. Hard water can leave white spots on glassware and reduce detergent effectiveness.
Signs of damage:
- Film on dishes
- Poor cleaning results
- Sluggish performance
Solution: Use a dishwasher-safe water softening agent or install a whole-home water filtration system.
Washing Machines
Effect: Scale buildup in hoses, valves, and drums reduces efficiency and increases wear. Detergents don’t lather well in hard water, leading to soap scum on clothes and poor cleaning.
Signs of damage:
- Clothes feel stiff or look dull
- Foul smells from buildup
- Premature mechanical issues
Solution: Use detergent boosters or install a water softener. Replace inlet filters regularly.
Refrigerators with Water Dispensers/Ice Makers
Effect: Sediment and hard minerals clog small water lines and filters, reducing water flow and ice quality. Chlorine may also affect taste.
Signs of damage:
- Poor water pressure
- Cloudy ice cubes
- Odd taste or smell
Solution: Replace fridge filters on schedule and consider a point-of-entry filtration system.
Coffee Makers and Kettles
Effect: These small appliances are especially vulnerable to scale buildup from hard water, which reduces heating efficiency and changes the taste of your beverages.
Signs of damage:
- White mineral deposits inside
- Slower heating
- Bitter taste in coffee or tea
Solution: Clean regularly with vinegar or descaling solutions, and use filtered or softened water.
