Is Tap Water Safe to Drink? Debunking Common Myths

April 10, 2023 · 4 min read

Clean and safe drinking water is essential for our health and well-being. It’s a basic necessity that we rely on every day for cooking, drinking, and other household activities. However, there is often confusion and misinformation about the safety of tap water. In this blog, we will debunk common myths and provide a comprehensive understanding of tap water safety, so you can make informed decisions about your drinking water.

Myth #1: Tap water is not safe to drink.

Let’s clear the big one out of the way right away. Generally, tap water in the United States is safe to drink. The United States Environmental Protection Agency (EPA) sets strict regulations for drinking water quality under the Safe Drinking Water Act (SDWA). Municipalities are required to test and treat tap water to meet these standards, which include limits on harmful contaminants such as bacteria, viruses, chemicals, and heavy metals. Most public water supplies undergo regular testing and treatment to ensure that the water is safe to drink.

Myth #2: Bottled water is safer than tap water.

Bottled water is not necessarily safer than tap water. In fact, about half of all bottled water comes from the same source as tap water – municipal water supplies. Bottled water is regulated by the FDA, which has different standards than the EPA for tap water. While both tap water and bottled water must meet safety standards, tap water is subject to more frequent and rigorous testing. Additionally, plastic bottles used for bottled water can pose environmental concerns due to their production, use, and disposal.

Myth #3: Tap water contains harmful chemicals and contaminants.

Fact: Tap water may contain trace amounts of certain chemicals and contaminants, but most of these are regulated and kept within safe limits by the EPA. Water treatment plants use various methods such as filtration, disinfection, and chlorination to remove or reduce contaminants. However, it’s important to note that water quality can vary depending on the location and condition of the water supply system. Older plumbing infrastructure, private wells, and other factors can potentially impact water quality. If you have concerns about your tap water, you can contact your local water supplier to request information on water quality testing results.

Myth #4: Tap water is not suitable for certain groups of people, such as pregnant women, infants, and elderly.

Fact: Tap water is generally safe for all groups of people, including pregnant women, infants, and the elderly. In fact, tap water is often the best choice for infants, as it contains important minerals like fluoride that are beneficial for dental health. However, certain populations, such as those with weakened immune systems, may be more vulnerable to waterborne contaminants. If you have specific health concerns or conditions, it’s best to consult with your healthcare provider for personalized advice.

Myth #5: Using a home water filtration system is necessary to make tap water safe.

Fact: While using a home water filtration system can provide an additional layer of protection, it may not be necessary for most households. As mentioned earlier, tap water in the United States is subject to strict regulations and testing to ensure its safety. However, if you have concerns about the taste, odor, or specific contaminants in your tap water, a home water filtration system can be an option. There are various types of filtration systems available, such as activated carbon filters, reverse osmosis systems, and UV disinfection units. It’s important to choose a filtration system that is certified by a reputable organization, such as NSF International, to ensure its effectiveness.

All that to say, unless you’re in a very specific locale and there’s been a disaster of some sort, tap water in the United States is generally safe to drink. It is subject to strict regulations and testing to ensure its quality. While tap water may contain trace amounts of certain chemicals, most of them are regulated and kept within safe limits. However, it’s always a good idea to stay informed about the quality of tap water in your area, follow any advisories or notices from your local water supplier, and take necessary precautions to ensure the safety of your drinking water.

If you have specific concerns about the quality of your tap water, you can consider using a certified home water filtration system or getting a water quality test from a certified laboratory. Remember to properly maintain your plumbing fixtures, avoid disposing of hazardous substances down the drain, and use certified water treatment products if needed. With these measures, you can enjoy clean and safe tap water for you and your family’s health and well-being.

How to Respond Quickly When a Major Pipe Burst Occurs

A major pipe burst can flood your Tucson, AZ home in minutes. Stay calm, act fast, and call an emergency plumber once you've stopped the flow. How to Deal With a Major Pipe Burst, Fast Protect Your Family If you've got small children or pets nearby, get them out of the affected area right away. Either the water itself or an electrical issue could endanger them, and they won't know how to stay out of your way or keep themselves safe. Shut Off the Water Head straight to your home's main shutoff valve: don't worry about assessing the damage or grabbing any belongings yet. Turn the valve clockwise until it stops. In most homes this valve is in the basement near the water heater, by the front foundation wall, or where the main line enters from the street. Turn Off the Electricity If the burst is near any outlets, lights, or appliances, turn off power to those areas at your breaker box. Only do this if you can reach the panel safely without stepping in deep water. If it feels risky, leave it alone and wait for help. Drain Remaining Water from the Pipes With the main water supply off, open all the cold-water faucets in the house and flush the toilets once. This relieves pressure and empties the lines so there's less water to keep spraying from the burst spot. Leave the faucets open until the flow slows to a drip. Document Everything Before Cleanup Get photos and videos of the damage right after you've stopped the water. You'll want evidence of the burst pipe, your wet floors, any affected walls and furniture, and damage to any belongings. You will need this for your insurance claim later, and the insurance companies will need proof that the damage came from this burst pipe rather than something else. Move Belongings and Contain the Water Lift rugs and move electronics, furniture, and important papers out of the wet zone. If the water is spreading, roll up towels or use plastic sheeting to block doorways and keep it from reaching other rooms. Work fast but safely. Don't carry heavy, soaked items if they're too heavy for you, and focus on irreplaceable items first, like photos, electronics, and documents. Call a Tucson, AZ Emergency Plumber Don't wait if water is involved, because every minute you lose is another minute for mold to grow or a new problem to develop. A good emergency plumber can isolate the problem, make a temporary repair if it's after hours, and plan for a permanent fix as soon as possible while coordinating with a restoration team. Start Removing Standing Water While you wait for the plumber, use mops, towels, a wet/dry vacuum, or buckets to get water off the floor. The faster you remove it, the less it soaks into subfloors or walls. Open the windows and run fans to improve airflow if the weather allows. Your aim is getting the area as dry as possible. You've got this. Act fast, and call us at Economy Plumbing Service, LLC at 520-885-3510 for the best emergency plumbing service in Tucson.

Tankless or Traditional: What’s the Best Water Heater Option for Your Home?

The decision between tankless and traditional models for replacement water heaters in Tucson can make a real difference in your daily comfort and long-term costs. Let's take a closer look at how each type works, which will help you pick the right fit for your household. Traditional Heaters Traditional tank-style water heaters store a set amount of water, usually 40 to 80 gallons, in an insulated tank and keep it hot constantly using either gas or electricity. When you turn on the faucet, hot water flows from the tank while cold water refills it at the bottom. Tankless Heaters These heaters only give you hot water when you need it. Cold water passes through a heat exchanger inside the compact unit, and out comes hot water, nearly instantly. Pros of Both Let's consider the pros of the traditional heaters first: They're cheaper up front Installation is simpler because most homes already have the connections in place When it needs replacing, it's simple and often same-day They can handle a high flow rate (lots of usage simultaneously) The pros list for the tankless heater is also enticing: Less wasted energy from water being heated when it's not needed No running out of water, no matter how many people take showers Longer tank lifespan Takes up less space Cons of Both Here's the downsides to be aware of with traditional heaters: They use more energy (much more, in some cases) They run out of hot water, and you have to wait while they refill They're bulky and need more room for placement They need to be replaced sooner than tankless As for tankless heaters, be aware that: Installation costs are usually higher Initial purchase price is higher Flow rate is lower unless you invest in a bigger (or multiple) units Scale can form inside the heat exchanger faster than in a tank model Best Water Heaters in Tucson: Local Factors There are a few local factors that might also influence your decision. We have hard water, so that means scaling is more of an issue. Both types of heaters need to be flushed to prevent buildup, but the tankless might need it more often. We've also already got high energy bills with the hot summers we have here, so trimming that with a tankless model can make a big difference over time. Tankless water heaters pay for themselves in energy savings in about seven years, and if you take care of your model, it can last up to 20.If you're still weighing the options for your specific setup, give us a call at Economy Plumbing Service LLC here in Tucson at 520-885-3510.

Are Your Gas Lines in Safe? Warning Signs You Can’t Ignore

We rely on our gas lines in Tucson to heat our homes, give us instant hot water, power our stoves, and more. Keeping your gas line safe is a serious responsibility, because the dangers of a problem in the gas line can be deadly. Here's some warning signs to look out for. Warning Signs That Gas Lines in Tucson Are in Trouble Emergency Signs Some warning signs are emergencies, and you cannot ignore them. Call your gas provider or emergency services and leave the area immediately if: You smell a sulfurous odor in or immediately around your house People in the house are suddenly and inexplicably experiencing headaches, dizziness, nausea, or shortness of breath If gas is escaping into the house, it can cause you and your family serious physical harm. The gas, as you breathe it, begins to displace the oxygen in your blood. You gradually asphyxiate or suffocate if you are exposed to too much for too long. Non-Emergency There are other warning signs that are less immediately serious, but you need to pay attention to them, regardless, as they could quickly turn serious: Corrosion Always inspect your pipes regularly, and if you see rust or other corrosion on them, be sure to call a qualified contractor right away. There may also be an issue if you notice flaking or bubbling of paint near your gas lines or a lot of dampness and residue around the fittings. A professional can seal joints and even replace a bad section of pipe if needed. Hissing If you hear hissing near a gas appliance or a meter, it likely means that gas is escaping. Even a little bit of a leak can increase your bills, of course, and indoors, it can create a very dangerous condition. Contact a professional contractor right away to take a look. If it's a single appliance, turn off the gas to that appliance. Bigger Bills If your habits haven't really changed, but the cost of your gas bill keeps going up, try turning off all your gas appliances and writing down the meter reading. Then, wait for an hour or two and check the meter again. If it has gone up, you have a leak. Low Pressure If the flame on your stove or in your furnace doesn't have the power it should have, then you could have a leak somewhere in the line leading to that appliance, or there could be a blockage. There also could be a faulty regulator in the appliance itself or corrosion in the piping. If several appliances seem to be affected, then the issue could be farther down the line and could be either your responsibility or something that your utility company needs to deal with. A contractor can investigate the situation and help you figure out what's going on. If you're noticing any issues with your gas line, schedule an appointment with us at Economy Plumbing Service LLC in Tucson or call us 24/7 at 520-885-3510.
