Water Leak Repair (Part 1) – Install a Frost Proof Faucet

Happy New Year everyone! For our first post of 2018, we're getting down to some serious home repair issues starting with water leaks.

Some of you may remember the reveal of my craft studio in our newly finished basement. I was also supposed to reveal the mancave right on its heels, but there was a good reason why that didn’t happen for a long time. One morning I went into my craft studio and noticed a swooshing sound coming from the area carpet underfoot; not a good sign. I then found this on top of my dresser:
The cup was supposed to be empty and now it was full of water!

Then I looked around and saw that all of our perfectly fitted and caulked baseboards had warped and popped off the walls.
Patches of paint were cracked and peeling on hub’s once-flawless drywall.
Eeeeek – we had a water leak!! But what caused it?

I noticed that the path of the water was near the window, however the drywall damage was right up against the edge of a cabinet which suggested that the water might not have come in from the window itself.

It was right underneath the end cabinet where the water had gathered in the cup on top of my dresser. I opened the cabinet door and discovered that all my books were soaking wet. I removed them and when I looked up, I saw the access hole for the shut-off valve to our outdoor faucet and suspected a leak in the pipe could be the culprit.
Once I determined that the leak wasn’t currently active, there was nothing more that I could do to until hubs got home from work; I didn’t want to disturb the ‘scene of the crime’ until he was there to help determine where the water had come from. Finding the source was going to require some investigative work to rule out a myriad of possibilities.

Once hubs got home, we took down the cabinet to investigate further and get better access to the water shutoff.
Although there wasn’t an active leak, there was dampness. We had to act quickly to prevent mold damage, so we turned our attention to clearing out the room. In part 2 of this series, I’ll show you what we did to remediate mold.
The Culprit
So what actually caused our leak? Our frost proof faucet burst. Below you can clearly see the split in the pipe. Before we could proceed to put my craft studio back together, hubs had to remove the frost proof faucet and replace it with another one.
We were scratching our heads wondering what could have caused our frost proof faucet to fail when it’s guaranteed frost proof. Are you wondering too? Well, a frost proof faucet is only foolproof AS LONG AS YOU DON’T FORGET TO REMOVE THE HOSE. You can get away with not turning off the water, but you have to disconnect the hose before winter comes! We’re not 100% certain, but there’s a good chance that hubs forgot to detach our water hose last fall. When winter settled in, the water probably back up from the hose, froze in the pipe and caused the split. Then in the spring, when he went to turn on the tap to fill the  pond in our backyard, we got more than we bargained for. In retrospect, I now realize why it seemed to take longer than normal to fill the pond last spring: some water was going into the pond and some right into our basement!

What’s that – more questions? You might also be wondering “why didn’t you just call the insurance company to come take care of the repairs?” For one, we have a deductible. Since hubs initially did all the work to begin with, he was able to do the repairs himself for much less than the deductible would have been. But it wasn’t just a matter of the money; hubs was so proud of the work he did in the basement that he didn’t want any old contractor slapping it back together. It had to be just as perfect as it was before and the only way to do that is to do it yourself. Secondly, we didn’t want our insurance to go up either when we had the capability to make our own repairs; we’ve never made a claim, but who knows?

The only drawback to fixing this mess was that it took a long time and I was without a craft space in the interim. Actually, there was more than one drawback: lets not forget how exhausted poor hubs was after renovating the basement single handedly in the first place. All he wanted to do was finally sit and relax in his mancave but then the leak happened – poor guy! He barely had a chance to enjoy the fruit of his labour and now he had more labour again than he ever bargained for.

The picture below demonstrates the forces of nature: you can see how frozen water burst open the stem of the sillcock (as compared against the new replacement).
By installing a frost free outdoor faucet, you will decrease the chances of having a pipe burst in your home (just don’t forget to remove the hose in the fall!).

Below is our new replacement. By the way, the plastic wedge that we removed in the picture is provided to compensate for lap siding installations. It slips between the frost-proof flange and the siding to form an attractive finish and solid base for mounting. Since ours was a brick application, we didn’t use it.
A properly installed frost-free sillcock will have a slight downward pitch, as shown on my blog (see link at end of post), so that when the water is turned off, the water will all drain out of the stem. If you fail to do this, the water will sit inside the stem of the sillcock even when it’s turned of and you’ll end up with the same burst pipe as you saw above. This is something we double checked when we replaced our old one (and why we took the extra precaution of enlarging the bottom of the hole)!

The first order of business is to find the shutoff valve and turn off the water. In our house the shutoff is in the ceiling, but if you have a newer home, the valve is typically located right next to the main water valve.

If for some reason you don’t have a shutoff, you’ll need to turn off the water main until the new installation is done. If you have a plumber doing this work for you, you might want to ask him to install a shutoff for future convenience.
Once the water is turned off inside the house, open the outside faucet to allow any water to drain. You need to drain whatever water might still be in the pipe so you can de-solder the pipe connections to remove the old one.

To de-solder the connections, you’ll need some gloves, a wrench and a propane torch. To prep the area, put a piece of tin foil against the joists so you don’t catch the wood on fire – you don’t want to burn your house down in the process of preventing further water damage, do you? As you can see by the scorch mark above, the contractor that built our house didn’t bother with this step!

Put on your gloves, hold the pipe with a wrench and apply heat to the joints to ease them apart. Remove the old sillcock from the outside.

To ensure a better downward pitch, hubs increased the length of the hole.
It gave him more leeway to adjust the pitch. He did a dry fit with a level to ensure that the sillcock would indeed have a downward pitch.
Note that if you were working with siding instead of brick, you would use the supplied plastic wedge behind the flange before inserting the sillcock into the hole. You would then secure it to the siding with wood screws before soldering the connections on the inside to keep it perfectly level (you can see a picture of that on my blog).

Back on the inside, hubs cleaned the copper pipe with some fine sandpaper to make a solid new connection to the silcock. You need to ensure the pipe is clean of any debris or the solder will not seat properly.

Before soldering, make sure the new sillcock valve is in the open position to let hot gases escape and avoid burning the rubber seat washer (you could burst the pipe again). Hubs then added some flux and soldered it all together to make the new connection.
While hubs was soldering, I was holding the pipe on the outside with heavy duty heat proof gloves to keep it level. It would have been best to secure it to the brick with tapping screws but we didn’t want to take a chance they wouldn’t hold – or make our hole even bigger. (If you don’t find a way to keep it level, it will likely twist while it is being soldered. It’s important to keep it level (but still on a downward slope) or it may not drain properly – and the last thing you want is to potentially cause the leak cycle all over again!).
To test whether the soldering job was successful or not, on the inside you can add some liquid soap around the joint, then turn the water back on. If there are any bubbles, you have a leak and must start again.

To finish off, we used a quick set concrete.
We first moistened inside the hole around the brick with water to prepare for the concrete application. I'm afraid I'm nearing my picture limit, so to see more detailed pictures you'll have to visit my blog at the link below.

We mixed up the concrete in an old container with some water. To fill the gaping hole and keep it neat, we scooped the concrete into a ziplock back, then cut a hole in the bag and squeezed it into the hole.

Don't be tempted to merely use caulk on the outside instead of cement; the hole is too big and will be an invitation to critters, like mice, to find their way into your cosy home if it's not sealed properly with cement. You can however use some caulk on the inside to seal the pipe to the rim plate before you re-insulate (as you can see in the before picture - 6th from the top).

By the way, if you have an older home, have never turned off the water before winter and have never experienced a pipe burst, that's probably because all your heat is escaping through the rim plate and keeping your pipes warm (instead of you!). You're probably bleeding money on your heating expenses! Proper insulation combined with a frost free faucet can save a lot on heating bills! I learned that the hard way too - with my very first house.

The concrete repair of the hole turned out beautifully and we could water our garden once again!

Back on the inside of the house, we re-insulated the rim space before we close up the ceiling again.

We can’t laugh about this episode quite yet, but mistakes do happen and things are only fail-proof to a point, so it’s a hard lesson learned. Anyway, our pain is your gain, because if you live in a colder climate and don’t already have a frost proof faucet, you should install one!

Remember, if you have a standard sillcock, you MUST turn off your water AND disconnect your garden hose in the fall. With a frost-proof sillcock you don’t have to turn off the water, but you DO have to disconnect the hose. Don’t make the same mistake that we did; learn from our mistakes 🙂

Next time in this 3-part series, I’ll be explaining how we did mold remediation after the leak and how to get a ‘level 5 finish’ on your drywall repairs so you can achieve a flawless finish too.

    The exact same thing happened to me. I was lucky, I caught it right away before there was any damage. Great instructions on the repair.

      Thank you Ginger! You're so lucky you caught it; I wish we had before it flooded my new craft studio :)

    Another thing you can do for the indoor shutoff is to install a ball valve, which is easier to turn off and makes it obvious that the water is off. Then disconnect the hose outside, and open the outside faucet to drain it completely. Make sure the caulking or foam around the sillcock where it enters your house is firmly in place, with no gaps for cold air. Lastly, we use one of those Styrofoam insulating covers over the faucet, to keep it free of ice and snow, and keep the heat of the house close to the faucet. The covers are available at Home Depot and Lowes, etc., and are only a couple of dollars.
