Well, I figured it would happen sooner or later. I have two Clayton Mark 5451 Yard Hydrants in my garage. One is over a single laundry tub. I put a valve on the end so that I could regulate the flow when I wash my hands etc. Well, I forgot to open the valve & close the hydrant & the head of the hydrant froze & split. I bought the hydrants about 6 yrs. ago at Farm & Fleet. I have spent the last hour searching for a replacement head. Haven't had any luck. The paper that has the parts & instructions for the hydrant says Clayton Mark Inc. Rogers, AR 72757. Anyone out there better than I am at locating the part for this hydrant?
