How To Replace a Hose Bibb

After watching your hose bibb leak all summer long, it may be the right time to replace it right before old man winter comes in to rob us of our joy. Most times, homeowners call up their local plumbing contractor to replace their frost proof hose bib because it looks too damn difficult. If you’re one of those homeowners, please read on. Hose Bibb replacement is not near as difficult as you think. Clearly, since you’re here, you know the definition of a hose bibb. However, to recap, it’s simply your outside spigot. As a result, we completed out first step together which is knowing what this hose is!

Plumbing Pro Tip: As fall fades and the freezing temperatures return to the Midwest and Northern states, please remove your garden hose from your hose bib. It’s a quick and easy way to ensure that your water lines serving the hose bibb or sillcock won’t freeze and eventually leak.

Split Pipe

This is exactly what you’ll find!

Here is the reason; too often, water sits inside the piping leading to the hose bib. If water is present and it does freeze, the water will free itself by expanding and bursting the piping. This is why so many hose bibbs are replaced during the first thaw, not because there’s a kink, loose bolt or screw. The homeowner doesn’t know their water line has split because it’s been frozen for 3 months. Without knowing what causes the problem, they won’t understand how to winterize pipes. As the water warms, the leak becomes visible.

Step #1: Find the Connection Point

Step #1: Find the Connection Point

You have to find the connection point between the water supply and the sillcock. If you have an unfinished basement, this is usually pretty easy. You can look where the hose bibb is on the outside of the house and then go into the basement and approximate where it ties in inside the house.

There is enough room to shorten the hose bibb and include a shut off valve

To make it easier on yourself, you can use windows or landmarks or bring a tape measure to hit it right on the nose. If your basement is finished with a drop ceiling, you’ll have to pop a few ceiling tiles to find the connection. It’s when you have a drywall ceiling that things can get interesting. Obviously in this case you want to use a tape measure and be as exact as possible to minimize the ceiling opening.

Plumbing Pro Tip: I have run across several exterior hose bibbs that were placed in a location with little or no forethought went into how it would be repaired if it should ever fail. Remember it’s much easier to buy a longer garden hose than it is to uncover a hose bibb buried inside a garage wall, wedged next to the foundation. In this case, call your local licensed plumbing contractor to come and fix it right.

Step #2: What Kind of Connection Do You Have?

A frost-proof hose bib comes in several different connection types. By connection types I mean the hose bib has to connect to the water supply in some way. Those connection types are as follows:

  • MIP (Male Iron Pipe) Connection – The threads on the end of sillcock are exposed, and they would thread into a FIP (Female Iron Pipe) adaptor at the connection point.

Sweat MIP Adapter

Sweat MIP Adapter

  • FIP (Female Iron Pipe) Connection – The threads at the end of the sillcock are on the inside so there would be a MIP adapter soldered at the connection point and the sillcock would screw onto the adapter.

FIP Adaptor

Sweat FIP Adapter

  • Sweat Solder Connection – This is hard connection. The end of the sillcock will have a solder fitting cup at the connection point which would slide over the water piping, and a solder connection would have to be made.Nonetheless, figuring out how to solder copper pipe can be easy with the right directions.

Plumbing Pro Tip: The soldered connection is the most difficult connection to make. Unless you love to solder things or are in the trades and soldering is a familiar skill, steer clear of a soldered connection. Also, it makes it more difficult to replace should the hose bibb malfunction in the future.

Step #3: Find Length of the Hose Bibb

Figure out the length of the hose bibb. Frost proof hose bibbs come in different lengths meaning their connection points to the interior water supply can be made closer to the interior wall or further inside the building. Hose bibs come in lengths starting at 4” and increasing incrementally by 2” all the way to 24”, the most common being 6”, 8”, 10” and 12”. There are directions you’ll find on the major manufacturers’ websites that talk about measuring the wall thickness. However, please disregard them. Common sense tells you to replace your hose bib with one that is the same length as the one being replaced.

You can lengthen or shorten if you have to, but if it isn’t necessary, leave it alone. Measure the length of the unit from the back of the wall plate to the end of the sillcock and that will get you your length. You may have to remove the defective unit to measure. If this is the case, please remember to turn shut off the water supply to the hose bib. If no isolation valve is present, you may have to shut down the water to the entire house. Once the water is shut off, turn on the faucet to drain any water left in the line.

Step #4: Choose Connection Type Of New Frost-Proof Faucet

Decide what connection you are going to use with the new frost proof faucet. I spoke above about the type of connections you may see fit. However, in the last 10 years or so, many different connection styles have become available. If you have a threaded connection whether it be MIP or FIP, it’s pretty easy to use the same connection to replace.

Step #5: Shut Water off before Making Repair

Please remember to shut off the water and to drain remaining water from the water line servicing the hose bibb. If you have a MIP or FIP connection, just unthread existing one. You can use a pipe wrench and channel locks or two pipe wrenches. The second can be used as a hold back or for leverage.

Once the old faucet is removed, place the new one through the existing opening. Come back inside and prepare the male threads with Teflon tape or pipe dope to ensure a positive seal. Screw in the new hose bibb into place until threads are fully engaged.

Step #6: Turn Water Back on

If you had to shut off the main water supply, turn on the faucets in the house including the new hose bib. Turn on the main water supply and let the water run until the water runs freely from all faucets, Make sure there is no air exiting the faucets. When the water is back on and running, you’re back in business.

Plumbing Pro Tip: I mentioned above about there being different types of connections being developed over the last decade or so. I think they are worth mentioning especially one in particular.

Connection Types to Consider When Replacing a Frost Proof Hose Bib

PEX Tubing – PEX has been used globally for quite some type and it’s finally seeing widespread use here in the U.S. There are several ways to join PEX pipe and fittings together. One of the more popular joining method involves a spline fitting and a clamp that is crimped sealing the fitting. Wirsbo also makes a very popular PEX joining system as well.

Compression – This is by no means a new way to make water connections but I’ve never seen or used a compression connection to install an exterior hose bibb. This involves a straight piece of copper pipe, reamed of course, a compression ferrule just like you’d see on supplies to a kitchen or bathroom sink faucet and a compression nut to tighten the joint and ensure a watertight seal.

Types of Hose Bibbs

There are many different types of hose bibs you could be dealing with. Here are some of the most common.

Since there are so many different brands to choose from obviously the material of the hose bibb will vary. Here are the different types of materials you could be dealing with. Chrome Hose Bibbs

Here is a picture of a​ typical hose bibb that shows everything from a packing nut to a bibb washer.

Side note: If homeowners want to connect a line with constant pressure to a greenhouse, garden spot, or lawn area, they might revert to a plastic pvc pipe. You can even make a decorative spout for your home garden if you wish. You can think outside the box and create an outdoor washer with using the correct pipes. Another idea is to add a lock to your hose bibb when you know it won’t be in use. The lockout of the water blocks unauthorized use of water, stops vandalism, inhibits leaks, and water waste. It comes with a key to unlock the hose bibb when it’s ready for use again.

***Greatest Plumbing Pro Tip: I’m apologizing in advance to all of my plumbing pro friends but I have to give out this tip. There are a ton of push fittings on the market right now, Shark Bite by Cash Acme is the most popular but there are others like Blue Hawk.

These are almost ridiculously simple to install. If you can’t figure out how to install using the instructions above, do the following. Shut water off, cut piping right in back of the hose bibb connection point, clean and ream piping to prepare. Buy a ½” FIP x Press adapter and thread it on the end of the new hose bib. Afterward, press it on to the bald end of piping making sure it’s on till it hits home. That’s it! It will literally take you under an hour. If you have no ball valve to isolate the faucet and you have room, you can add a press ball valve in the same fashion.

I hope that the above removes a little bit of fear if you have to tackle removing and replacing a frost proof hose bibb.

As always, thanks for reading.

    1. There is a little half circle tool that comes in each Sharkbite fitting bag that will help you remove the valve.
