Custom Molded Products of Newnan, Ga., is recalling about 16,000 diverter valve caps sold with Master Spas (an Authorized Partner) hot tubs and swim spas.

The valve cap can become loose, pop off and strike a bystander, posing an impact hazard.

The firm has received 112 reports of the valve caps popping off including four reports of consumers being struck by the cap. No injuries have been reported.

The clear valve caps are included as a component part and are located under the diverter handle on the upper deck of the hot tub/spa above the water line.

The valve caps, manufactured in China, were sold at Master Spas (an Authorized Partner) hot tub/spa distributors from December 2017, through May 2019, for between about $5000 and $45,000 and about $2 for the valve caps.
