There have been 112 reports of these caps popping off, including four instances where consumers were struck by the cap. Consumers should stop using their spa immediately and contact the manufacturer for a free replacement cap.
The valve cap can fail and pop off with significant force, posing an impact hazard that could strike and injure bystanders.
Consumers should immediately stop using the hot tubs and swim spas with the recalled valve cap and contact Custom Molded Products to arrange for a free replacement cap from their hot tub/swim spa manufacturer.
