Hard Water Guide · 2026
Why Scale Resistance Matters for Commercial Faucets
Hard water affects commercial facilities across the US. Mineral buildup can clog aerators, damage sensors, and reduce flow rates—leading to costly maintenance and replacement. BathSelect's commercial touchless faucets are engineered with ceramic cartridges, PVD finishes, and scale-resistant aerators to ensure reliable operation in hard water conditions.
How often should I clean the aerator in hard water areas?
In hard water areas (7-10 gpg), clean monthly with vinegar solution. In very hard water (10+ gpg), clean every 2 weeks. BathSelect faucets feature easy-clean aerators that can be removed without tools.
Do sensor lenses get affected by hard water scale?
Yes, mineral film can form on sensor lenses over time. Premium models like BS1110 feature hydrophobic coatings that resist mineral buildup. For standard models, wipe lenses weekly with a dry microfiber cloth.
What is the best finish for hard water areas?
PVD (Physical Vapor Deposition) finishes like chrome, brushed nickel, and stainless steel offer the best resistance to hard water spotting and etching. Our PVD finishes carry a 5-year warranty against mineral damage.
How long do ceramic cartridges last in hard water?
Ceramic disc cartridges typically last 5-7 years in hard water conditions with proper maintenance, compared to 10+ years in soft water. Regular cleaning of aerators helps extend cartridge life.
Can I retrofit my existing faucet for hard water resistance?
Yes, you can install scale-resistant aerators and replace rubber washers with ceramic cartridges where compatible. BathSelect offers retrofit kits for most commercial faucet models.
What warranty does BathSelect offer against hard water damage?
Most BathSelect commercial faucets include a 5-year limited warranty covering defects caused by hard water, including scale buildup affecting function. Proof of regular maintenance may be required.
What water hardness level requires special faucet considerations?
Water hardness above 7 gpg (grains per gallon) requires quarterly cleaning. Above 10 gpg, we recommend monthly maintenance and considering whole-building water softening for optimal faucet performance.
Are BathSelect faucets ADA compliant for hard water areas?
Yes, our ADA compliant models (BS1106 series) feature easy-grip handles that remain operable even with minor mineral buildup, and meet all ADA reach and force requirements.
