14 Things Bay Area Folks Can (and Should) Do Right Now to Prepare for an Earthquake

Those of us who live in the Bay Area understand that a major earthquake could happen at any time. If we want to live here—with the mountains, beaches and great weather—we have to make an uneasy truce with the massive fault lines running beneath our homes. Luckily, while we don’t have to like our rowdy underground neighbors, we can preemptively call the cops on the party. Do these 14 things now and be prepared for a major quake.

    1. Anchor tall bookshelves and other heavy or high furniture to the walls. Be sure to attach the items to the wall studs rather then the drywall.
    2. Do not hang pictures or mirrors over beds or the couch.
    3. Keep heavy objects on lower shelves.

A Crucial Component of Earthquake Safety

A Crucial Component of Earthquake Safety

OAKLAND — Due to concerns about earthquake safety, many Bay Area homeowners are taking preemptive action by having their homes retrofitted via measures like foundation bolting and bracing. While retrofitting is a great idea, there’s one caveat: if your home’s foundation is poor or weak, bracing and bolting won’t do much good. For example, when an earthquake strikes, a bolt that’s anchored in weak concrete could easily snap out of the side of the stem wall, which eliminates any of its intended benefits.

The best way to avoid wasting your money on pointless retrofitting measures is to hire a quality retrofitting company—preferably one that also handles foundation work. A company that doesn’t do foundation work may not be able to provide all the services you need or even inform you about them, but a well-regarded retrofitting company will give you the straight scoop and provide everything you’re looking for.

Assessing Your Home’s Foundation

Assessing Your Home’s Foundation

BRISBANE — Earthquakes are an ongoing concern for anyone who lives in the Bay Area. One way you can be proactive about protecting your home and family is to know the condition of your home’s foundation. If you understand the signs to look for, you can determine if measures are needed to bolster your home against earthquake damage.

Depending on when your home was built, the character (as well as the quality) of its foundation can vary. For example, many houses built in the 1920s and ’30s have foundations that were engineered using local materials, which isn’t good. Local sand contains impurities, which leads to degradation of the concrete. Also, builders in those days likely didn’t use enough Portland cement, as it was very expensive.

To assess the condition of your home’s foundation, perform this simple test: go down to your basement with a hammer or screwdriver and attempt to scrape off a piece of your foundation. If you’re successful, it’s a sign that the foundation’s integrity is compromised, in which case you should call a structural engineer.

Another thing to look for when assessing your home’s earthquake readiness is signs of foundation settlement, which can be caused by anything from poor soil compaction to drainage issues. In most cases, signs of foundation settlement can be found inside the home in the form of wall cracks, whether in corners or diagonally above doors and windows. Another common sign is a door or window that suddenly becomes difficult to open or close. If you start to notice these signs in your home, it might be time to get a professional assessment from a structural engineer.

Inspecting Your Water Heater

Inspecting Your Water Heater

CONCORD — For most homeowners, water heaters tend to be out of sight and out of mind. In reality, periodic water heater inspection is an important aspect of home maintenance, mainly because it allows you to preventatively identify problems like leaks and safety risks.

When inspecting your water heater, the first thing you should look for is proper safety. Due to earthquake concerns, any standard water heater installed in the Bay Area is required to have two support straps—one on the lower third of the tank and one on the upper third. These straps should be anchored to the wall by a sturdy support like a wall stud or post. Since most water heater tanks weigh more than 500 pounds, if yours shakes loose during an earthquake, the water and gas lines could be ripped loose.

Once you’ve verified the safety of your water heater, it’s time to check for water leaks. Start at the top of the tank and check connections like the water lines and shut-off valve for signs of moisture or corrosion. The next place to inspect is the drip pan beneath the tank. Everything should look dry—if you see water in the pan, you may have a leaky drain valve or flex line.

To preventatively identify leaks and safety risks, make it a point to inspect your water heater every six months.

How to Clear a Congested Drainpipe

How to Clear a Congested Drainpipe

CONCORD — Clogged drainpipes are common in many residential households, and one of the main culprits is grease from cooking. Over time, grease can settle on the bottom of a drainpipe and eventually create a stoppage. That’s why you should never pour grease down your sink drain when you’re cooking. Instead, let the grease sit until it congeals, then use a paper towel to wipe off the grease and throw it in the garbage.

When grease buildup is allowed to sit in a drain for an extended period of time, it can result in a congested pipe. In this situation, a drain snake (aka auger) won’t fix the problem—it’ll go through the stoppage and come back out without actually removing it. The only way to effectively clear a congested drainpipe is with hydro flushing. A plumbing technician will run a hydro line inside your drainpipe and apply water at a pressure of up to 2,000 PSI. This pressurized water will blow all the grease buildup out of the pipe and down the drain. Once cleared, your drain will function properly again.

How to Stop a Water Heater Leak

How to Stop a Water Heater Leak

CONCORD — If you discover a leak in your water heater, the first thing you should do is turn it off to prevent further leakage. However, in order to do so, you’ll need to know the correct procedure. Here’s how it’s done:

1. Turn off the water heater’s shut-off valve. Typically, this is found on the right-hand side of the tank. Grab the valve handle and rotate it a quarter-turn; this should stop water from entering the tank.

If the shut-off valve isn’t working, you may need to shut off water to your entire home (depending on how bad the leak is). Every homeowner should know the location of their home’s main water shut-off valve—it’s either just outside the home or at the sidewalk. This shut-off valve can also be used to prevent water damage in the event of a broken pipe or other major leak.

2. Turn off the gas. There are two ways to turn off gas to a water heater, the primary being the gas shut-off valve on the tank itself. Just like the water shut-off, give this valve a quarter-turn. If the valve isn’t working, you can shut off the gas via the water heater’s thermostat. Simply rotate the dial until it reaches the “Off” setting, which will extinguish the pilot light.

3. Call a plumber. Before calling, locate and write down your water heater’s model number and serial number. This information will let your plumber know what to expect before arriving.
