Designed to give the appearance of a smooth ceiling, Viking’s VK488 concealed sprinkler is suited for homes where water supply is limited, according to the company. With an 8 GPM flow rate, the product allows for reduced pipe sizes, smaller water meters, and elimination of a tank and pump. Sprinkler coverage extends up to a 16-foot-by-16-foot area. Three cover plate sizes—including a square option—are available in several standard finishes and custom colors.  The sprinklers feature a temperature rating of 165 F.  Viking Corp.
