The Watersafe WS-425W Replacement for Watersafe WS-425B Test Kit is the newest product from one of the most trusted names in the water testing industry - Watersafe. Testing your water yourself can save you money and give you results on the spot! No more waiting for days or even weeks for test results that have to be mailed in. The WaterSafe Water Test Kit shows you EPA standards and gives you accurate results within minutes. Also known as part number WS-425W or WS425W. It should also be noted that the EPA recommends regular testing (yearly or more) of your home's water if it is drawn from a private well. Regular testing will protect you and your family and ensure that you know exactly what is in your water.

Note: The manufacturer recommends the WS-425W as a replacement for the WS-425B. This item is labeled for well water applications, but it is also compatible with city water. The replacement kit even tests for more contaminants!
