New rules on appliances will affect your plumbing

The Environmental Protection Agency is requiring appliance repair shops to test for chemicals in their plumbing before letting customers use them, which could affect plumbing repairs and customers who are worried about pollution.

The rules, which take effect in April, are expected to require more than 1,000 shops to install test equipment and a new inspection tool.

The agency has not yet said how many of those stores will comply.

The new rules come after a number of incidents involving toxic chemicals, including the release of a toxic chemical in a gas tank in June that killed a woman and injured seven others.

The EPA said in a statement that the rules will make it easier for businesses to install safe and effective testing tools and equipment to detect chemicals in plumbing.

It also said it is taking steps to improve compliance with the rules.
