I'd like to hear about this as well. We have a frost free that leaks like crazy. Wondering what's going on in there. Since it's winter, have left it alone and just let it leak for now. I don't want a full blown broken water line this time of year
If it's a Woodford you can, but you still might have to screw the head off. Any part is availble. I'm not sure about the others.
Never use anything but the proper sized wrench on the packing nut. It's soft brass as is the rod. Absolutely never use a pair of pliers or adjustable wrench. The nut is easily distorted, and then you can never get it to make a proper seal that will last any length of time. Even with a proper sized wrench, you don't want to put much torque on it. If it takes more than a little pressure on the wrench, put in more packing.
Sadly, my hydrant is not a Woodford. It's a Clayton Mark. I bought the repair kit and it comes with no repair instructions, only instructions on how to adjust the flow and install a new hydrant. I was hoping that the head would not need to come off as I am not sure that I am strong enough to take it off by myself.
It takes two large pipe wrenches to screw the head off of any hydrant. I wouldn't even try it without a couple of 3 foot (at least) pipe wrenches. I guess you could put pipe on two smaller ones, but I don't like to do that sort of thing.
Whoo hoo! It's done. I got my neighbour to come and help me. He provided the muscle power and an extra long pipe wrench. I provided the diagrams of the hydrant and the information/instructions that I got from the internet. I am so relieved to have a hydrant that is not streaming water out of the top. Thank you everyone for your help. I am so happy!
