Hi Lynn J and lynne s

The danger of lead could still be there.The EPA said:

“even newer plumbing advertised as “lead-free” can still contain as much as 8 percent lead.”

I don’t know if this applies to water coolers and instant hot units. They both use copper pipe that runs through a heating coil similar to a radiator in a car. The water runs through the copper pipe and that is where the lead could get into the water.

The insta hot and the water cooler both use a holding tank (albeit small) to hold the heated water. This is where any minerals, metals or other impurities would build up and be re-absorbed back into the heated water.

So anytime you have a holding tank that is where impurities will build up. I would read up on how to clean and flush these tanks to remove any residue. Citric acid and vinegar are often used in coffee makers and water distillers to remove buildup.

It aint easy trying to do the best for our pups, but it sure is worth it!!!
