The federal government warns Americans not to buy cheap counterfeit faucets online that can immerse harmful chemicals and heavy metals in drinking water.

The Consumer Product Safety Commission said Wednesday it recalled four Chinese-made faucets sold on Amazon at unsafe lead exposure levels. It says lead can be particularly harmful to babies, toddlers and pregnant women.

The recall was a cheap foreign-made faucet sold on Amazon, the company told NBC News. Moen paid the International Association of Plumbing and Machinery Officials accredited pipeline certification body to test 19 best-selling cheap foreign-made products.

The IAPMO laboratory found that 17 of the 19 faucets failed to meet the national drinking water standard - lead 11, with 15 organic compounds including carcinogens and chemicals used to treat lice and scabies.

“Consumers who use these products and drink these water with these higher levels of contaminants will be at higher risk of things like cancer,” said Tom Palkon, chief technical services officer of IAPMO.

The government's recall was applauded on Capitol Hill.

D-Ill. “U.S. consumers will know they need to stop using all taps that may be purchased on these sites,” Senator Tammy Duckworth, the Senator told NBC News on Wednesday. “You need to ban people who cannot meet our safety standards.”

In March, Duckworth and RN.C. Senator Ted Budd wrote a joint letter to CPSC asking it to investigate imported pipe products, citing IAPMO's faucet test results.

Moen said the U.S. has sold 35 million cheap faucets from foreign brands over the past five years, citing industry e-commerce tools.

Faucets seem to be a bargain, around $30, and look very similar to the top American brands of faucets that can cost hundreds of dollars. This makes it difficult for consumers to name a high-quality fixture, Moen said.

“We’ve seen examples of how they copy all aspects of the product in it, from markings to trademark names and logos on our products,” said Aaron Bores, Executive Vice President of Product Development at Moen.

During a subcommittee on Wednesday’s U.S. Senate Intellectual Property Hearing Subcommittee, Powers asked the administration to close intellectual property loopholes that allowed the sale of fake faucets.

"When searching for this Moen valve on e-commerce, we found a real Moen sku. The same search resulted in 41 fake skus. Consumers had no chance to identify the real product from the fakes, nor did they have the most experienced plumbers."

Amazon has not responded to NBC's request for comment. Companies selling recalled faucets were unable to comment immediately.

In the recall, the CPSC said consumers should stop using the faucet immediately - adding that they can't drink alcohol from it until they poured in 15 seconds.

Palkon from IAPMO said consumers can look for certification marks on taps and verify them through online certification agencies or by calling the agency. He said consumers can also use water filters to remove some heavy metals and chemicals.
