There is a very specific kind of excitement that comes with packing for a trip. Whether you\u2019re heading off to visit the grandkids, going on a quiet retreat, or just escaping for a few days to a cozy bed and breakfast, the anticipation is wonderful. But right before you walk out the door, you pull out your phone and see it: a viral video telling you to cover your sink drains with a plastic bag and an upside-down glass, or to stuff a shower cap down the drain.<\/span><\/div>\n
\n
<\/div>\n
The video claims this “hack” will stop sewer gas from entering your home and keep creepy crawlies out while you\u2019re gone.<\/span><\/div>\n
<\/div>\n
Well, I immediately felt my heart rate tick up a little bit. At 73, living alone, I am incredibly proactive about my health. I\u2019m always keeping a close eye on my circulation, trying to understand those sudden purple blotches on my arms, and doing everything I can to prevent spikes in my blood pressure that could lead to a stroke or an aneurysm. And let me tell you, the anxiety of wondering,\u00a0<\/span>\u201cDid I do the sink hack right? Is my house going to fill with sewer gas?!\u201d<\/em>\u00a0is enough to raise anyone\u2019s blood pressure!<\/span><\/div>\n
\n
So, I did what I always do: I put the kettle on, grabbed my favorite mug of ginger tea, and looked into the actual plumbing science.<\/span><\/div>\n
<\/div>\n
Grab your favorite beverage, and let\u2019s separate the internet fiction from the old-fashioned, reliable facts, so you can lock your door and leave for your trip with total peace of mind.<\/span><\/div>\n
<\/div>\n

The Truth About the “Upside-Down Glass” Hack<\/span><\/h2>\n
Let\u2019s get right to the bottom of this. The short answer?\u00a0<\/span>You do not need to cover your drains with a glass, a bag, or a shower cap.<\/span><\/div>\n
<\/div>\n
Here is the fascinating kitchen-and-plumbing science behind why:<\/span><\/div>\n
<\/div>\n

The Magic of the “P-Trap”<\/span><\/h3>\n
If you look under your sink, you\u2019ll see a pipe that bends down and then curves back up in a “U” shape before going into the wall. That is called a P-trap. Its entire job is to hold a small pool of water.<\/span><\/div>\n
<\/div>\n
That little pool of water acts as a physical, liquid seal. It is what blocks heavy, smelly sewer gases from floating up the pipe and into your bathroom or kitchen. It also blocks drain flies and bugs.<\/span><\/div>\n
<\/div>\n

Why the Glass Hack Fails<\/span><\/h3>\n
Placing an upside-down glass or a plastic bag over the drain does absolutely nothing to stop sewer gas, because it doesn’t create an airtight seal. Gases will simply find a way around the edges. Furthermore, if you use a plastic bag and a rubber band, you\u2019re just creating a messy, sticky trap for hair and gunk that you\u2019ll have to clean when you get home.<\/span><\/div>\n
<\/div>\n
The only time sewer gas escapes is if the water in that P-trap evaporates. But unless you are leaving your house for six months with the heat blasting, the water in your P-trap will not evaporate during a standard vacation!<\/span><\/div>\n

The “Real Deal” Checklist to Actually Protect Your Home<\/span><\/h2>\n

Continued on next page<\/p>\n

Instead of worrying about upside-down glasses, let\u2019s use a few minutes to do the things that\u00a0<\/span>actually<\/em>\u00a0protect your home and your peace of mind. Lowering your travel anxiety is the best thing you can do for your heart and your circulation!<\/span><\/div>\n
\n
<\/div>\n

1. The 30-Second Water Run<\/span><\/h3>\n
Right before you walk out the door, turn on every sink, shower, and bathtub in the house for about 30 seconds. This guarantees that every single P-trap in your house is filled to the brim with fresh water, creating a perfect, impenetrable seal against sewer gases and bugs.<\/span><\/div>\n
<\/div>\n

2. Turn Off the Main Water Valve<\/span><\/h3>\n
This is the ultimate old-fashioned wisdom! If a hose bursts or a toilet runs while you\u2019re gone, it can cause thousands of dollars in damage. Find your main water shut-off valve (usually in the basement, garage, or near the water heater) and turn it off. It takes ten seconds and saves you from a massive headache.<\/span><\/div>\n
<\/div>\n

3. Unplug the “Vampire” Appliances<\/span><\/h3>\n
Unplug your toaster, coffee maker, and microwave. Not only does this save a little electricity, but it also protects these appliances from unexpected power surges while you\u2019re away.<\/span><\/div>\n
<\/div>\n

4. Adjust the Thermostat<\/span><\/h3>\n
Don\u2019t turn the heat or AC completely off, or you risk frozen pipes in the winter or mold in the summer. Just adjust it to an “eco” setting\u2014about 60\u00b0F in the winter and 80\u00b0F in the summer.<\/span><\/div>\n

The “Welcome Home” 3-Ingredient Avocado & Chickpea Smash<\/span><\/h2>\n

Continued on next page<\/p>\n

There is nothing quite like the feeling of walking back into your own home after a trip. The house is safe, the air is fresh, and the plumbing is working perfectly! But traveling can be exhausting, and the last thing you want to do is cook a massive meal.<\/span><\/div>\n
<\/div>\n
Since I am always looking for ways to support my circulation and keep my blood vessels relaxed after the stress of travel, I always have the ingredients ready for my\u00a0<\/span>3-Ingredient Welcome Home Avocado & Chickpea Smash<\/span>.<\/span><\/div>\n
\n
It takes exactly five minutes, requires zero cooking, and is packed with the heart-healthy fats and fiber my body craves after a trip. And because my children absolutely do not share my love for avocados, I get to enjoy the whole bowl myself!<\/span><\/div>\n
<\/div>\n

Ingredients You\u2019ll Need<\/span><\/h3>\n
    \n
  • 1 can (15 oz) chickpeas:<\/span>\u00a0Rinsed and drained very well.\u00a0<\/span>Substitute: Cannellini beans work beautifully for a creamier texture.<\/em><\/li>\n
  • 1 large, ripe avocado:<\/span>\u00a0The star of the show! The monounsaturated fats are fantastic for relaxing blood vessels and supporting healthy circulation.<\/span><\/li>\n
  • 1 tablespoon fresh lemon juice & a pinch of sea salt:<\/span>\u00a0The acid brightens the flavor and keeps the avocado beautifully green.<\/span><\/li>\n<\/ul>\n
    <\/div>\n

    Step-by-Step Instructions<\/span><\/h3>\n
    1. The “Rough” Mash:<\/span>\u00a0Pour the rinsed chickpeas and the scooped avocado flesh into a medium bowl. Using a fork or a potato masher, gently mash them together.\u00a0<\/span>Crucial tip: Leave it chunky!<\/em>\u00a0You want the texture of the beans to contrast with the creamy avocado.<\/span><\/div>\n
    <\/div>\n
    2. Season and Rest:<\/span>\u00a0Drizzle the fresh lemon juice over the top and sprinkle with sea salt (and a little black pepper if you like). Fold it gently. Let it sit for 2 minutes so the flavors meld.<\/span><\/div>\n

    \n
    3. Serve with “Vessels”:<\/span>\u00a0Since I love setting up interactive food bars, I turn this into a “Welcome Home Topping Station.” I set the bowl on the counter and surround it with crisp cucumber rounds, toasted baguette slices, and sturdy crackers. I keep a jar of toothpicks nearby so I can easily spear a cucumber round and scoop up a perfect bite of the mash.<\/span><\/div>\n
    <\/div>\n
    Because this dish is so rich, creamy, and bright, it pairs absolutely beautifully with a crisp, chilled glass of Sauvignon Blanc. The acidity of the wine cuts right through the richness of the avocado, making it feel like a celebratory “I’m home!” dinner.<\/span><\/div>\n
    <\/div>\n

    Frequently Asked Questions<\/span><\/h2>\n
    Q: What if I already have drain flies in my bathroom?<\/span>\u00a0A: If you see tiny fuzzy flies hovering around your sink, it means there is organic buildup in the pipe\u00a0<\/span>above<\/em>\u00a0the water line in the P-trap. The glass hack won’t fix this. Instead, pour a pot of boiling water down the drain to flush it, or use a natural enzymatic drain cleaner.<\/span><\/div>\n
    <\/div>\n
    Q: Should I cover my drain if I have a mouse problem?<\/span>\u00a0A: If you are worried about pests, covering the drain isn’t the answer, as mice can chew through plastic and squeeze through tiny gaps. Instead, focus on sealing the gaps around your plumbing pipes under the sink with steel wool and caulk. And remember my favorite trick: soak cotton balls in peppermint essential oil and tuck them under the sink! Mice despise the smell.<\/span><\/div>\n
    <\/div>\n
    Q: Is it safe to leave the water in the P-trap for a month?<\/span>\u00a0A: Yes! As long as your home is climate-controlled (not freezing cold or sweltering hot), the water in the P-trap will easily last for a month or more without evaporating. If you are leaving for six months, just pour a tablespoon of mineral oil down the drain before you leave; it floats on top of the water and prevents evaporation.<\/span><\/div>\n
    <\/div>\n

    Let\u2019s Travel with Peace of Mind!<\/span><\/h2>\n
    I truly hope this takes the worry out of your next vacation. It is so empowering to know that we don\u2019t need to fall for stressful internet hacks when good, old-fashioned plumbing science has already solved the problem for us. By taking ten minutes to run the water, turn off the main valve, and unplug the toaster, you are protecting your home and, more importantly, protecting your own heart health by letting go of travel anxiety.<\/span><\/div>\n
