The 421 Series Internal Vacuum Breaker Hydrant was added to PRIER's offering in March of 2009.

The 421 Series Hydrant is the result of spending a significant amount of time with our plumbing contractor customers and continuing to respond to their needs in the field. A common complaint among contractors with any freezeless wall hydrant with an external vacuum breaker was the operation of the vacuum breaker, often leaking due to debris in the potable water system or customer neglect, resulting in a callback for the contractor. With the 421 Series Internal Vacuum Breaker Hydrant, PRIER has made the vacuum breaker integral to the operating stem, eliminating any leakage through the vacuum breaker on the top of the valve. As with most wall hydrants, any hoses should be removed in freezing temperatures. The valve is approved to ASSE, IAPMO and CSA standards.

The 421 Series is a "smart-turn" design, 180 degree opening and closing for easy operation and flow control.

The 421 Series is made in lengths at PRIER from 4" to 14", in 2" increments, with six different inlet options.
