For those with older homes which may still have copper piping, please note that in a lot of cases plumbers used lead-based solder to connect the older copper pipes. Over time the lead from that solder typically found its way into the water carried by those pipes. If you suspect that you may have these older pipes and solder-based connections in your home, we suggest that you use one of the following lead in water drinking water test kits on a periodic basis:
Should any of the results turn up positive for lead, meaning your drinking water contains 15ppb or greater concentration of dissolved lead, we highly recommend you have your water evaluated by a certified water professional.
Although we keep repeating ourselves, do-it-yourself drinking water test kits serve as great screening tools for the average consumers but no one should ever rely upon them as their sole testing method. Remember: It’s your water, your health, your life.
