Test results suggest that your water may cause excessive scale formation in your plumbing and appliances.
Your water is considered very hard. Very hard water is high in calcium and magnesium, which people often associate with good tasting water. Excessive scale build up can occur on pipes. This can shorten the lifespan of pipes and appliances. Signs of hardness include white deposits on appliances and soap scum build up in sinks and showers.

Test results suggest the potential for excessive scale formation on plumbing and appliances. Scaling occurs when water has high levels of minerals like calcium carbonate that build-up on surfaces. While slight scaling is beneficial for protecting pipes from corrosion, excessive scaling can be harmful, causing: (1) reduced efficiency of your hot-water heater, (2) reduced or blocked flow to fixtures or appliances, and (3) soap scum.

These minerals and metals can be related to your plumbing. This means they could be coming from your pipes or they could be affecting your plumbing and appliances.

Depending on the ions present, high total dissolved solids (>500 mg/L) can lead to excessive scaling in water pipes, water heaters, boilers, and household appliances such as kettles and steam irons, which can lead to shorter service lives of these appliances.
Sulfate can form scale on plumbing fixtures and the walls of pipes. Indirectly, sulfate that fuels sulfur-reducing bacteria creates the conditions for producing hydrogen sulfide gas, which can be corrosive to pipes.

At relatively low concentrations, manganese can deposit on the coating inside pipes, which may subsequently slough off and release black solids into the water.
