Dirty, Discolored Water

Brown, yellow, or cloudy water from your tap can have several possible causes — from sediment and changes in the water supply to corrosion in older household plumbing. A water test and inspection help identify the source so you can address it correctly.

Smelly, Bad-Tasting Water

A rotten-egg, chlorine, metallic, or musty taste or odor can make water unpleasant to drink and use. Unusual tastes and odors can result from several conditions, including naturally occurring compounds, plumbing components, or changes in the water supply. Testing helps identify the cause so you can address it.

Hard Water & Scale Buildup

Chalky white crust on faucets, showerheads, and appliances is limescale from hard water. Hard water contains dissolved calcium and magnesium that leave mineral deposits behind. Testing your water hardness is the first step to understanding your conditions and choosing the right solution.

Spotty Glasses & Dishes

Cloudy, spotted glasses and film on dishes after washing are a common sign of dissolved minerals in hard water. The minerals are left behind when water evaporates, leaving white spots and haze. Testing your water hardness helps you understand the cause and choose the right solution.

Dry Skin & Hair

Hard water can leave mineral residue on skin and hair after showering, which may make skin feel dry or hair feel rough, dull, or difficult to manage. Water hardness testing helps you understand your home's water conditions. Dry skin and hair can have many causes, so a test is the right first step rather than assuming water is the only factor.

Mineral buildup from hard water can make hair feel rough, dull, or difficult to manage and may contribute to scalp buildup. Water hardness testing helps you understand your home's water conditions.

Staining on Sinks & Fixtures

Orange, brown, or black stains on sinks, tubs, toilets, and faucets are often caused by iron, manganese, or other minerals in your water.
