Unaware of the term “hose bib” you came across online while researching a plumbing issue?
Well, most homeowners are unfamiliar with such technical terms associated with plumbing systems, so know that you’re not alone. But learning about it beforehand will ensure you’re able to understand a related plumbing issue that might crop up in the future.
That’s why I’ve tried to help you with this guide on what is a hose bib setscrew.
What Are Hose Bibs?
If you aren’t aware of hose bibs, we’d suggest taking a look around the exterior of your home.
You’ll surely find an outdoor tap or hose spigot on the rear portion, if not at the front. In effect, “hose bib” is another term used for these outdoor taps. They come with threaded spouts that let you connect the garden hose for using water outdoors.
And once you’re done with the daily chores, you’ll just need to turn off the valve since the design of the hose bib helps drain out water from its exterior part. Note that this mechanism prevents the freezing of the water in the spigot and the consequent damage.
The Role Of Setscrews in Hose Bibs
The setscrew in a hose bib refers to the screw fixed at its center that attaches the handle to the spigot body. It helps keep the handle tight to the spigot.
People tend to mistake the setscrew as a portion of the spigot stem and assume that it’s causing internal leakage. But here’s the real picture — you’ll only need to adjust the setscrew if the handle of the outdoor faucet loosens and causes leakage.
Adjusting A Hose Bib Setscrew
If you find the handle to be loose and notice water leaking from it, you’ll need to proceed in the following way to adjust the setscrew:
Step 1
Begin by attaching a hose to the outdoor spigot to divert the water flow during the adjustment.
Step 2
Next, rotate the handle of the spigot counterclockwise to resume the water supply. Then fix the setscrew using a Phillips-head screwdriver and turn the handle clockwise to stop the water flow. Finally, examine the handle to make sure it’s tight.
In case it doesn’t tighten properly, you’ll have to try the next few steps.
Step 3
You’ll have to stop the water supply to the outdoor spigot first. Note that the shutoff valve for the purpose is either located under the house or in the basement.
Step 4
Now, open the handle so that the remaining water drains entirely and detach the set screw using a Phillips-head screwdriver.
Step 5
To complete the procedure, apply Plumber’s Tape or some sealant to the threads of the setscrew, and install it back into the handle. Make sure to tighten the setscrew with the screwdriver.
With that, your outdoor tap will stop leaking, so you can resume outdoor water use immediately.
Preventing Leakages In Hose Bibs
Remember when I talked about how operating the shutoff valve of a hose bib effectively can help drain out water from its exterior part? Well, you can’t completely rule out the possibility of forgetting to turn off the shutoff valve or disconnecting the hose attached to the spout.
In such cases, water won’t drain out from the hose bib entirely, and when winter arrives, it might freeze and cause the hose bib to crack. And this, in turn, leads to continuous water leakage till the unit is replaced.
To prevent such possibilities, here are some simple steps you can take before the winter season:
- Make it a habit to turn off the shutoff valve the moment you’re done with your outdoor watering chores
- If you’ve already left the valve on for a few days, detach the hose bib and drain the water from the hose to store it in a secured area
- Each time you disconnect the hose, resume the water flow from the hose bib to let the excess water run out
- If you find the shutoff valve leaking, leave the outdoor tap on through the winter so that the leaked water can escape instead of freezing within
- In case of shutoff valve leakages, you can also place a bowl below the bleeder valve that’s fixed underneath.
Final Words
Now that you have a clear idea about the functioning of hose bibs and set screws, I’m sure you’ll be able to handle these fixtures tactfully. Here’s a pro-tip before I sign off — if you live in a region with an extreme climate, consider installing a frost-free hose bib designed to prevent freezing during winter.
See you next time!
