I have had mine in my kennels for 7 years and have never had a problem. Bryant I put a shut off at the end off mine. And when I want to drain it before a freeze I shut the water off and open shut off valve then open my closet facet and it all runs out the hose .
x2 on the block and bleeds...have had mine for many years without problems...even the pups learn pretty quick on how to use them...
