Choosing the Right Water Heater for Your Home

When it comes to water heaters, homeowners typically have two main options: traditional tank water heaters and tankless water heaters. Understanding the differences between these two types can help you make an informed decision that best suits your home’s needs. At Riverway Plumbing & Mechanical, we're here to provide you with all the essential information.


How Does a Storage Tank Water Heater Work?


A traditional tank water heater stores hot water in an insulated tank, which can hold between 30 and 80 gallons. The heater continuously heats the water, keeping it ready for use. Here’s a breakdown of how it works:


  • Cold Water Supply: Cold water enters the tank from the bottom through a dip tube.
  • Heating Process: A gas burner or electric element heats the water.
  • Heat Rises: As the water heats, it rises to the top of the tank.
  • Hot Water Outlet: Hot water is drawn from the top of the tank when you turn on a hot water tap.


How Does a Tankless Water Heater Work?


Unlike traditional water heaters, tankless models do not store hot water. Instead, they heat water on demand using a powerful heat exchanger. Here’s how a tankless system operates:


  • Cold Water Entry: Cold water enters the unit when a hot water tap is turned on.
  • Heating Process: A gas burner or electric element quickly heats the water as it passes through the exchanger.
  • Hot Water Outlet: The heated water is then delivered directly to the tap, shower, or appliance.


Storage Tank Water Heaters: Pros and Cons


Advantages:

  • Lower Upfront Costs: Tank water heaters are generally less expensive to purchase and install.
  • High Capacity: Can supply hot water to multiple fixtures simultaneously.
  • Simplicity: Easier to install and repair compared to tankless models.


Disadvantages:

  • Energy Inefficiency: Continuously heating water can lead to higher energy bills.
  • Space Requirements: Requires significant space for installation.
  • Limited Lifespan: Typically lasts 10-15 years with maintenance.
  • Risk of Leaks: Tanks can develop leaks over time, potentially causing damage.


Tankless Water Heaters: Pros and Cons


Advantages:

  • Energy Efficiency: Heats water only when needed, reducing energy consumption.
  • Space-Saving: Compact design takes up less space.
  • Longer Lifespan: Can last up to 20 years with proper maintenance.
  • Less Risk of Leaks: No tank means less chance of leaks and water damage.


Disadvantages:

  • Higher Upfront Costs: More expensive to purchase and install.
  • Installation Complexity: May require modifications, such as new gas lines or venting.
  • Limited Availability: Not as widely available as traditional tank models.


Sizing and Cost Considerations


Storage Tank Water Heaters

  • Sizing: Determine the size needed based on your household’s peak hour demand. This can be calculated by adding up the flow rates of all hot water fixtures used during the busiest hour.
  • Cost: Installing a tank water heater can range from $2,000 to $5,500, depending on whether it’s electric or gas.


Tankless Water Heaters

  • Sizing: Based on your home’s water usage and the required temperature rise. Calculate the gallons per minute (GPM) needed during peak usage times.
  • Cost: Installation costs for tankless heaters can start at $8,000, reflecting their higher efficiency and longer lifespan.


Which is Right for You?


Choosing between a tank and tankless water heater depends on your home’s specific needs and your long-term goals. Here are some key points to consider:

  • Immediate Needs: If you need a quick and affordable solution, a tank water heater may be best.
  • Energy Savings: For long-term savings on energy bills, a tankless water heater is more efficient.
  • Space Constraints: If space is limited, a tankless unit’s compact size is advantageous.
  • Lifespan: Tankless heaters offer a longer lifespan, which might justify the higher initial cost.

Your water heater is one of the hardest-working systems in your home, providing hot water for showers, laundry, and cleaning every day. But without regular maintenance, it can lose efficiency, develop leaks, or even fail prematurely. To help you avoid costly repairs and extend the life of your water heater, the experts at Riverway Plumbing & Mechanical have put together these four essential water heater maintenance tips every homeowner should follow. 1. Inspect Your Water Heater Regularly Take a few minutes every few months to visually inspect your water heater for signs of rust, corrosion, or leaks. Even small drips or rust spots can indicate internal damage or pressure issues that should be addressed by a licensed plumber. Early detection can prevent serious water damage and extend your unit’s lifespan. 2. Test the Pressure Relief Valve (T&P Valve) Your temperature and pressure relief valve is a crucial safety feature that keeps your water heater from building up dangerous pressure. To test it: Lift the valve’s lever partway, then let it snap back. You should hear a quick burst of water into the drainpipe. If nothing happens or it leaks afterward, it’s time to replace the T&P valve. This simple test helps protect both your home and your water heater. 3. Check the Temperature Setting For safety and efficiency, make sure your water heater thermostat is set to 120°F (49°C). This temperature prevents bacteria growth, reduces the risk of scalding, and lowers energy costs. A professional plumber can help adjust or replace a faulty thermostat if your water doesn’t feel consistently warm. 4. Review Warranty & Service History Always keep track of your water heater’s installation date and any previous maintenance or repairs. Regular professional service helps keep your warranty valid and ensures your system is performing at its best. 💧 Schedule Professional Water Heater Maintenance Even with proper homeowner maintenance, a professional inspection can catch hidden problems such as sediment buildup, rusted components, or inefficient heating elements. At Riverway Plumbing & Mechanical , we provide thorough water heater maintenance, repair, and replacement services to keep your system safe, efficient, and reliable year-round. 👉 Schedule your professional water heater service today!

Trenchless Pipe LIning

Sewer repairs and replacements have traditionally been a daunting task, often involving extensive excavation, disruption to landscapes, and significant costs. However, the advent of advanced UV cast-in-place pipe technology has transformed this process, making trenchless pipelining a viable and efficient solution for sewer repairs and replacements. What is UV Cast-In-Place Pipe Technology? UV cast-in-place pipe technology is a cutting-edge method that utilizes ultraviolet light to cure resin-saturated liners within damaged pipes. This innovative approach allows for the creation of a new, seamless pipe within the existing one, without the need for digging up the property or performing street cuts. How Does It Work? The process begins with a thorough inspection of the damaged sewer pipe using a small camera. This inspection helps identify the extent of the damage and the best approach for repair1. Once the pipe is cleaned and prepped, a flexible liner coated with UV-sensitive resin is inserted into the pipe. The liner is then inflated and cured using UV light, which hardens the resin and forms a durable new pipe within the old one. Benefits of Trenchless Pipe Lining 1. Minimal Disruption : One of the most significant advantages of trenchless pipe lining is that it eliminates the need for excavation. This means no digging up lawns, driveways, or streets, preserving the property's aesthetics and reducing the inconvenience to homeowners and businesses. 2. Cost-Effective : Traditional sewer repairs can be costly due to the labor and machinery required for excavation. Trenchless pipe lining reduces these costs by minimizing the need for extensive digging and reducing the time required for repairs. 3. Quick and Efficient : UV cast-in-place pipe technology allows for rapid curing times, often within minutes. This speed not only reduces the overall repair time but also minimizes the downtime for the sewer system. 4. Durability : The cured-in-place pipe created using UV technology is highly durable and resistant to corrosion, ensuring a long-lasting solution to sewer problems. Applications and Future Potential UV cast-in-place pipe technology is suitable for various applications, including residential, commercial, and municipal sewer systems. Its ability to navigate bends and transitions within pipes makes it a versatile solution for complex sewer networks. As technology continues to advance, the potential for UV cast-in-place pipe technology to revolutionize sewer repairs and replacements is immense. With ongoing improvements in materials and methods, this trenchless approach promises to become even more efficient and cost-effective, paving the way for a future where sewer repairs are quick, seamless, and minimally disruptive. Conclusion Advanced UV cast-in-place pipe technology is a game-changer in the field of sewer repairs and replacements. By offering a trenchless solution that eliminates the need for excavation, it provides a cost-effective, efficient, and durable method for addressing sewer issues. As this technology continues to evolve, it holds the promise of transforming the way we approach sewer repairs, making them less intrusive and more sustainable for the future.

Have you ever noticed strange sounds coming from your plumbing? Groaning, moaning, whining—these noises may seem harmless at first, but they often signal underlying plumbing issues that need attention. Ignoring them can lead to bigger, more expensive problems down the road. At Riverway Plumbing, we’ve heard it all, and we know exactly what these sounds mean. Here’s a breakdown of common plumbing noises and what they’re trying to tell you. Common Plumbing Noises and Their Causes 1. Groaning or Moaning Pipes – High Water Pressure  If your pipes are producing a deep, groaning sound, your water pressure might be too high. While strong water pressure may seem beneficial, excessive pressure puts stress on your pipes and can lead to leaks, pipe damage, and wasted water. What to do: Check your water pressure with a pressure gauge, which you can find at most hardware stores. The recommended range is between 40 and 60 psi. If your pressure is over 80 psi, you may need a pressure regulator installed to prevent long-term damage.

Water leaks are more than just an inconvenience—they can lead to serious damage to your home and belongings if left unchecked. While visible leaks like dripping faucets are easy to spot, hidden plumbing leaks can be much trickier to detect. Fortunately, there are several ways to uncover these sneaky leaks before they turn into a major problem. Here’s how you can identify a hidden plumbing leak in your home. 1. Conduct a Water Meter Test One of the most reliable ways to detect a hidden leak is by checking your water meter. Start by turning off all faucets and water-using appliances in your home. Then, check your water meter reading. If the meter continues to move, even when no water is running, you likely have a hidden leak. For slow leaks, take another reading after a few hours and compare the results. 2. Test Your Water Pressure A sudden drop in water pressure can indicate a plumbing leak. If you’ve noticed weaker water flow from faucets or showerheads without an obvious cause, you may have a hidden leak somewhere in your plumbing system. A professional plumber can help pinpoint the issue if the pressure continues to drop. 3. Listen for Unusual Sounds Even if you can’t see water, you may be able to hear it. If you notice a faint sound of running or dripping water behind walls, under floors, or in ceilings, it’s a strong sign of a hidden leak. These sounds are often more noticeable at night when the house is quiet. 4. Inspect Your Appliances Household appliances like dishwashers, refrigerators, and washing machines are common culprits for leaks. Check underneath and behind these appliances for any signs of moisture or puddles. If you find a leak, it’s important to address it quickly before it leads to bigger water damage. 5. Test Your Toilets Toilets are another common source of hidden leaks. An easy test is to drop a few drops of food coloring into the toilet tank before going to bed. If you find the color in the toilet bowl by morning without flushing, you have a leak that needs repair. 6. Monitor Your Water Bill A sudden spike in your water bill without a change in usage can indicate an undetected leak. If your bill is consistently higher than normal, it’s worth investigating further by performing some of the above tests. 7. Look for Dampness and Water Stains If you start noticing wet spots, water stains, or discoloration on your walls, ceilings, or floors, these could be warning signs of a leak. Over time, hidden leaks can also lead to mold and mildew growth, causing musty odors and potential health hazards.

As the summer winds down and the back-to-school rush begins, it’s easy to overlook small issues around the house—especially when they don’t seem like emergencies. That slow drip under the sink, the faucet that never quite shuts off, or that toilet that runs a little too long might not feel urgent… but ignoring them could cost you. August is actually the perfect time to tackle those plumbing issues before they turn into major repairs or costly water bills. Here's why. 1. That Drip Adds Up—Fast A leaky faucet can waste hundreds of gallons of water over just a few weeks. If you're seeing a steady drip, you could be literally pouring money down the drain—especially during peak summer water usage. Fixing a faucet or worn washer now is quick, affordable, and saves you in the long run.

As temperatures rise during the summer, homeowners tend to focus on their cooling systems. However, your plumbing system is also more prone to certain issues during this season. Increased water usage, outdoor activities, and summer storms can lead to unexpected plumbing problems. At Riverway Plumbing, we want to help you stay ahead of these potential issues. Here are the most common plumbing problems to watch for during the summer months—and how to prevent them. 1. Clogged Shower and Tub Drains Spending time outdoors often means bringing dirt, sand, and other debris back inside. When you wash off in the shower or tub, these particles can accumulate in your pipes, leading to slow drainage or even blockages. To prevent clogs, use a drain cover and rinse off outside when possible before heading into the shower. 2. A/C Not Cooling Properly Few things are worse than a malfunctioning air conditioner during a heatwave. If your system isn’t cooling efficiently, it could be due to: Dirty air filters Low refrigerant (especially if your system is still using R-22) Frozen coils Thermostat issues Replace filters monthly, keep the outdoor unit clear of debris, and schedule a professional tune-up in late spring or early summer. 3. Garbage Disposal Problems Summer cookouts and holiday gatherings often result in more food scraps being tossed into the garbage disposal. Items like corn husks, fruit pits, and grease can clog the disposal and damage the blades. Avoid disposing of fibrous or hard items, and run cold water when using your garbage disposal. 4. Poor Indoor Air Quality With windows closed and A/C running constantly, indoor air can get stuffy—especially with pollen, dust, and humidity in the mix. Solutions: Install high-efficiency air filters (MERV 8–13) Consider a whole-house dehumidifier Keep your HVAC ducts clean and sealed

As summer approaches, ensuring your HVAC system is in top shape can make a big difference in comfort, efficiency, and energy costs. With a few simple maintenance steps, you can keep your air conditioning running smoothly during the hottest months. Here are our top 5 tips for preparing your HVAC system for summer. 1. Replace Your Air Filters Your HVAC system relies on clean air filters to maintain proper airflow and indoor air quality. Dirty or clogged filters can reduce efficiency, forcing your system to work harder and consume more energy. Aim to replace your filters every 1-3 months, or more frequently if you have pets or allergies.
