WATTS 709/909 2 1/2-3" CHECK COVER KIT

2 1/2-3 Backflow Cover Repair Kit, Series 709

Model Overview

This is a double check assembly. The 3/4"-2" were produced from 1979-1993. The 2 1/2"-10" sizes began production in 1979. The 3/4"-3" size body is constructed of bronze. In the 3/4"-2" sizes, the internal hardware parts are made of plastic and bronze. Watts also has a hot water version available on the 3/4"-2" sizes. This was designated by an HW after the model number e.g.: 709HW. The 21/2"-10" size bodies are cast iron with a fused epoxy coating. The 2 1/2"-3" size are available in either bronze or fused epoxy coated cast iron. Internal hardware parts are made of bronze and stainless steel. Check seats are replaceable on all sizes and springs are contained on all sizes when covers are removed. In 2010 a LF model was introduced in sizes 2 1/2"-10" which replaced the leaded bronze parts with stainless steel to make a lead free assembly. Rubber repair kits are the same for the LF and non LF assemblies.
