ALWAYS put Teflon thread sealant back on anything that’s threaded when you put it back together: http://www.permatex.com/products-2/product-categories/thread-compounds/thread-sealants/permatex-thread-sealant-with-ptfe-detail
It not only improves the seal, but makes it easy to get back apart next time.
I didn’t realize that Woodford had their own repair video. It really is a simple operation. Larger pipe wrenches will get the top off of even an old one without heat. Several things I don’t like in this video are the use of an adjustable wrench, clamping vise-grips onto the replacement seal rod, and not using any anti-sieze on reassembly.
You do need to use vise-grips on that rod, but make sure you don’t clamp them on where the rod slides through the seal.
An adjustable wrench won’t hurt anything if the nut will come out easily, and you adjust the wrench correctly. I don’t like those “ifs”. Use the properly sized open end wrench.

I’ve never had to use heat on one, but all ours are Woodfords, and have some sort of sealer/anti-sieze on the threads to start with. Any time I put a head back on, I put some anti-sieze on the threads after the Teflon tape is started. Even if you have to buy two pipe wrenches, it’s probably still cheaper than hiring a plumber.[/QUOTE]
Tom,
My hydrants are all Campbells, but Campbell seems to have been acquired by some other company and it is getting harder to get the replacement parts.
Do you know if the threading on the hydrant head is a standard, so if one goes, I could replace it with a Woodford?
gumtree-I did have to go buy the wrenches, but with almost 3’ bury, I am much happier doing maintenance from above, and not digging because the size of a hole to get down there to replace is a LOT of digging.
I wouldn’t take any kind of odds on a bet that they would be interchangeable-not so much about the pipe threads, but the seat down at the bottom.
That would be an easy upgrade though, if it did work.
I just checked with Google, and repair parts are still very much available for Campbells: http://www.amazon.com/Campbell-Yard-Hydrant-Repair-Kit/dp/B000H5WHOK
If you put the sealant on the threads for the head, you should be able to stop at exactly the same place it was before you took it off, and it not leak. Don’t keep cranking on it to get it tighter. Without sealant/anti-seize, you might have to turn it past where it was when it came off.
