How to Repair a Broken or Leaky Melnor Hose Nozzle
It’s summertime and it’s time to water the lawn and the flowerpots. So today I’m going to show
you how to fix a hose nozzle. Over time the springs inside that run along the plunger tend to rust out and break, so you find yourself pushing back here to
shut the hose off . I find that to be a real pain. I’m going to show you how to do this repair. It’s simple! The tools you’ll need are a flathead screwdriver, a Philips head screwdriver (preferably magnetic), and if you go to Home Depot or any
hardware store, you can get a set of springs. This is a steel and stainless steel spring assortment. Say that a couple times fast. They cost about $4.37 for a quick and easy repair. So I’m going to show you how to do it now. The first thing you’ll want to do is unscrew this cap on the back. Make sure that’s completely off of the plunger. Then you’ll want to use your Phillips head screwdriver to remove the screw in the front and this is usually a big screw. And I usually end up doing this repair because, while this Melnor hose nozzle comes with a warranty, which is usually three years (I’ve seen one year and three years), I
always seem to lose the receipt. Melnor is usually good about sending a new one the first time it breaks, but not so much the second time. So you remove this cap and underneath you’ll see this little spring-loaded button and
that’s what creates the clicking noise when you turn the knob. I’ll see if I can do
that for you. When you select your spray pattern that’s
what makes the clicking noise. You don’t want to lose that. Then there’s this little rubber gasket here you don’t want to lose that. If it falls out, just push it back in. Now take your Phillips head screwdriver and remove these two screws. These are short screws. You can see there’s some rust on them and since they’re not very strong metal, be gentle. Then take a flathead screwdriver and pry this piece off. One thing I typically do is mark the top and the bottom so I remember what direction it goes on. The water comes out of here so if you put it on the bottom, the water will come out of the bottom. Pull this out. You can see inside here. There’s some rust from the spring rusting out. The usual failure with these are that the springs they use rust out and break. What you see here are there were two rubber gaskets and then this metal washer that fits into the spring to prevent the spring from going against the gasket. Now you pull out the plunger and I’ll pull out the spring to get a look at that. You can see how it’s rusty. It’s
ready to go. Usually when I open these up the spring is in pieces. Pull out the plunger… that was just my screws from the front falling out. Put those aside. And here’s a look at the plunger. You want to check your gaskets while you’re in here. Make sure the gasket looks healthy or else when it plugs the hole, water will continue to leak out. Now I go into my spring assortment purchased at the local hardware store
and I find springs that are relatively the same length. If I can’t find a
comparable spring, I’ll find two screws that are
roughly about the same length. These are going to have a little more tension than this one, but that’s okay. It’ll work great. So I will put the small
spring on the plunger first. Move it all the way to the top. Take the next size spring and put that on. This will give it some super tension. You can always cut the springs back if you think they’re a little too taut. I’ll take my metal washer put that on. Followed by my two rubber gaskets. Then I’ll put the plunger back into
the shaft here. Actually, no sorry I don’t want to do that. I want to put it in the
other shaft. I want to put it down in here. And I’ll need to use some push
power to push in the plunger so it comes out the back. See that over here?
Push that back and then attach the cap. I want to make sure I get that cap nice and tight. Let me show you the cap before I do that. The cap comes out. There’s a big section here and a small section here and you just slide the cap in the bottom and push it up. Then you push the plunger all the way back and screw the cap onto the plunger. You want to make sure it’s nice and tight because if you don’t get it tight you can strip the plastic knob. You don’t want to strip the plastic knob. There we go. We have some nice spring action there. Now we’ll take this piece. Make sure that
the gasket’s in there and put that little clicker back in in a moment.
Push this this in. This takes a little bit of pressure. I may need to get off camera and get out my trusty sledgehammer — for “when things want to be broken.” You want to make sure this is seated in real well or else water will leak out the sides. There we go! And because these screws are super short — that go in here — We’ve got to make sure it’s nice and snug in there. And the screws will do the remaining 5% of the job, but because the screws are so short,
you don’t want them to strip. Now here’s where the magnetic
screwdriver comes in handy. You can put these two screws back in. And again, you want to make sure that’s nice and snug although you want to go gentle on those screws
because they’re not well-made. That’s good! Nice and tight. Good. Now we’ll put our little
spring-loaded clicker back in. Put the top back on… and it doesn’t matter what position this goes in. Re-attach our front screw. Then we should be good to go. Like I said, it’s pretty simple. Anyone
can do it! And if you get everything nice and tight
you won’t have any leaks. If you do, go back and tighten all your screws. We’ve got some nice action here now and I don’t have to use my finger to push that plunger back in. If you got everything put back together
nice and tight? Back in business! One more thing. You may need to loosen this just a little because if this yellow knob here is too tight … see the water come out the front?… the plunger is not closing.
That means you’ve got to loosen this yellow knob. I’m trying to do it with one finger. And that will close it. Notice I’ve got no leaks. Back in business! If you have a little leak down at the bottom here like I do, that means I need to replace the washer in the bottom. I’ll show you what that looks like because I’ve got another one right here. You see that black rubber ring right there? You can get those real cheap at
your local hardware store. You just pull the ring out and put in the new one. I hope this review has been helpful. If it has, please do me a favor and like it, and thank you so much for watching. Happy watering!
