100DVF-DMF4 1″ Dura Manifold 4 Valve Set-Up with Rainbird 100DVF Valves

I was most concerned that these valve stations would survive a winter freeze. I have two and both did. The normal operation of these valves by automatic controller and manually is great. I would only suggest that the end cap have some better means of tightening and untightening by hand. It is difficult to grip it tight enough while it is located in a valve box.
