Test results do not indicate definite issues with excessive scaling or corrosion of plumbing or appliances, though these outcomes are still possible.
Your water is considered soft, meaning it is low in calcium and magnesium. Naturally soft water may be corrosive if it also has low pH and/or alkalinity. However, softening your water is unlikely to change its corrosivity.



Test results suggest little or no risk of corrosion or excessive scaling of plumbing and appliances. If you’re still seeing significant white build up on appliances or fixtures, it might be silica.




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.

Lead is a naturally occuring heavy metal with harmful health impacts. Corrosion of plumbing is the largest source of lead in drinking water.

Copper is a naturally occuring metal that is widely used in plumbing. Corrosion of plumbing, faucets, and fixtures is the most common source of copper in drinking water.
