Can I Replace The Head Of A Yard Hydrant? Yes You Can!

What happens here

With the new head installed, the final step is to adjust it. First, tighten the packing nut to create a seal around the plunger rod, preventing water from leaking out the top when the hydrant is on. Next, adjust the set screw to set the handle's range of motion. Lift the handle, tighten the set screw so the handle stays up, then lower it to find the closed position. Loosen the set screw, reposition the handle to the fully closed position, and re-tighten the set screw. Turn the water supply back on and test the hydrant for proper flow and for any leaks. Make fine adjustments as needed.

Goal: Adjust for proper operation and test for leaks

Tools and materials

  • Adjustable Wrench DeWalt — Tightening the packing nut and adjusting the set screw
  • Bucket — Catching water during testing to check flow and prevent making a mess

I think we're going to opt instead of the thumb screw setup. We're going to opt for this square. And I think it is a better setup. These O-rings right here is essentially the packing nut, right? Just don't want that to leak and we'll adjust this a little bit more in a minute. We'll just get it a little bit tight for right now. All right, dude, go ahead. Just slowly. Yeah, cool. A little more. Oh, is it? That's all the way on? Okay, all right. Well, let's shut that down. It came out more when it was off. Yeah, let's go ahead and rod. Yeah, just the rod. We'll go this right here. Okay, tighten it up there. Yeah, let's tighten it up. We'll drop it and then we'll do it again. Okay, and we'll pop that up. Give that a little little more here. Probably, yeah. Yeah, I think that's it. Open this up and now we'll drop this packing nut down just a little bit more. Nothing crazy. See how that rolls? Third tip with this little sat screw is to have it up, tighten it down, bring it down, get it to where it's seated in place, loosen this up, put it in place and then tighten it down where you want it and that's going to guarantee you've got a good seal right there. Okay, and we're back in business. Yeah, cool. Worked out pretty well, man.
