Do I Need Soft Water Tank Storage Tank

Have you noticed a sudden drop in your water pressure after installing a water softener? Or perhaps your soft water seems to run out quickly, leaving you with hard water during peak usage times? These issues can be frustrating, and the question often arises: Do I need a soft water storage tank? This article will guide you through diagnosing the situation and determining if a storage tank is the right solution for your home.

Understanding the Problem: Soft Water Supply Inadequacy

The most common complaint we hear is inconsistent soft water availability. Here's the scenario: you invest in a water softener to enjoy all the benefits – less scaling, better soap lather, and softer skin. But, during high-demand periods like morning showers or doing laundry while the dishwasher runs, the soft water seems to disappear, and you're back to dealing with hard water problems.

This often manifests in a few ways:

Noticeable drop in water pressure during peak usage.
Sudden increase in soap scum after periods of heavy water use.
Clothes feel stiff and less clean when washing multiple loads in a row.
Water tastes different or has a metallic tang intermittently.

These symptoms suggest that your water softener isn't providing enough soft water to meet your household's demand. Before jumping to the conclusion that a storage tank is necessary, let's explore some possible causes and troubleshooting steps.

Step-by-Step Diagnosis: Is a Storage Tank the Answer?

Before considering a storage tank, it's crucial to rule out other potential problems. Follow these steps to diagnose the issue:

Step 1: Assess Your Water Softener's Capacity

The first step is determining if your current water softener is adequately sized for your household's needs. Water softener capacity is measured in grains, and it must be matched to your water hardness (measured in grains per gallon - GPG) and your household's water usage.

Here's how to check:

Determine your water hardness: Get your water tested. You can usually get a free test from your local water company, or purchase a DIY test kit from a hardware store. The results will tell you the GPG of hardness minerals (calcium and magnesium) in your water.
Estimate your daily water usage: A general guideline is 75 gallons per person per day. Multiply this by the number of people in your household. For example, a family of four would use approximately 300 gallons per day.
Calculate your softener's required capacity: Multiply your daily water usage (in gallons) by your water hardness (in GPG). This gives you the total grains of hardness your softener needs to remove daily. For example, 300 gallons x 10 GPG = 3000 grains.
Check your softener's specifications: Look at your water softener's manual or the manufacturer's website to find its grain capacity.
Compare: If your softener's capacity is significantly lower than the grains of hardness you need to remove daily, your softener is undersized.

DIY Fix: If your softener is undersized, replacing it with a larger unit is the best long-term solution. A storage tank won't solve the underlying problem of an insufficient softener.

Step 2: Check the Regeneration Settings

Water softeners need to regenerate – that is, clean the resin beads that trap hardness minerals – periodically. If the regeneration frequency is set incorrectly, the softener may not be regenerating often enough, leading to hard water breakthrough.

Here's what to do:

Locate your water softener's control panel: This is usually on top of the softener unit.
Access the regeneration settings: Consult your softener's manual for instructions on how to access the regeneration settings. These settings may be labeled as "regeneration frequency," "days between regeneration," or similar terms.
Verify the settings: Most softeners allow you to set regeneration based on time (e.g., every two days) or water usage (e.g., every 500 gallons). If your softener is set to regenerate too infrequently, adjust the settings to regenerate more often. A good starting point is every other day or based on your water usage calculations from Step 1.
Monitor water quality: After adjusting the settings, monitor your water quality for a few days. If the problem persists, you may need to adjust the settings again or consider other causes.

DIY Fix: Adjust the regeneration settings according to your water hardness and usage. Give the softener a few regeneration cycles to see if the problem improves. Be patient! It can take a few cycles to fully restore the resin bed's capacity.

Step 3: Inspect the Brine Tank and Salt Level

The brine tank is where the salt solution is stored that is used during regeneration. If the brine tank is empty or the salt level is too low, the softener won't be able to regenerate properly.

Steps to take:

Locate the brine tank: This is typically a separate tank connected to the water softener.
Check the salt level: The salt level should be above the water level in the tank. If the salt level is low, add more salt. Use the type of salt recommended by your softener manufacturer (usually rock salt, solar salt, or evaporated salt).
Inspect for salt bridging or mushing: Salt can sometimes form a hard crust (bridging) or a mushy layer at the bottom of the tank. This can prevent the salt from dissolving properly and interfere with regeneration.
Break up salt bridges: If you find a salt bridge, carefully break it up with a broom handle or similar tool. Be careful not to damage the tank.
Clean out salt mush: If you find salt mush, scoop it out of the tank. You may need to drain the tank and rinse it out thoroughly to remove all the mush.

DIY Fix: Maintain the correct salt level in the brine tank and break up any salt bridges or remove salt mush. This ensures the softener can regenerate effectively.

Step 4: Check for Water Leaks

Leaks in the water softener system can lead to wasted water and inefficient softening. Even small leaks can impact the amount of soft water available.

Look for these telltale signs:

Water pooling around the softener or brine tank.
Dripping from fittings or connections.
Unexplained water stains on the floor.

What to do:

Visually inspect all connections and fittings: Look for any signs of leaks.
Tighten loose fittings: Use a wrench to gently tighten any loose fittings. Be careful not to overtighten, as this can damage the fittings.
Replace damaged fittings or tubing: If you find any damaged fittings or tubing, replace them with new ones. Make sure to use the correct type and size of fittings.

DIY Fix: Repair or replace any leaking fittings or tubing to prevent water waste and ensure proper softener operation.

Step 5: Evaluate Your Well System (If Applicable)

If you have a well, the problem might not be the softener itself, but the well's ability to supply enough water. Well systems have a recovery rate – the rate at which the well refills after water is drawn out. If your household's water usage exceeds the well's recovery rate, you may experience pressure drops and insufficient water supply, especially during peak times.

Investigate the following:

Well pump capacity: Check the specifications of your well pump to determine its flow rate (gallons per minute - GPM).
Well recovery rate: This is more difficult to determine yourself. You might be able to find information on your well's report, if you have it. Otherwise, a well technician can test the recovery rate.
Compare: Compare your household's peak water demand (estimated in Step 1) to the well pump's flow rate and the well's recovery rate. If the peak demand exceeds the supply, your well system is the bottleneck.

DIY Fix (Limited): If the well pump is undersized, replacing it with a larger pump *might* improve the situation, but only if the well's recovery rate can support the increased pump output. This is a complex issue that usually requires professional assessment. Reducing water consumption during peak hours can also provide some relief.

When to Call a Professional

While many of these issues can be addressed with DIY solutions, there are situations where professional help is necessary:

Your water softener is undersized and you are unsure how to choose the right replacement. Professionals can assess your water hardness, water usage, and plumbing system to recommend the appropriate size and type of softener.
You suspect a problem with the water softener's internal components, such as the control valve or resin bed. These repairs require specialized knowledge and tools.
You have a well system and suspect the well pump or well itself is the problem. Well system diagnosis and repair should be left to qualified professionals.
You've tried all the DIY fixes and the problem persists. This indicates a more complex issue that requires expert troubleshooting.

Is a Soft Water Storage Tank the Right Solution?

After completing the diagnostic steps above, you should have a better understanding of the underlying cause of your soft water problems. If you've determined that your water softener is adequately sized, the regeneration settings are correct, and your well system (if applicable) is functioning properly, but you *still* experience soft water shortages during peak usage, then a storage tank *might* be the answer.

Here's how a storage tank can help:

Provides a buffer: A storage tank acts as a reservoir of soft water, providing a buffer during peak usage times. The softener can slowly replenish the tank between uses, ensuring a constant supply of soft water.
Evens out water pressure: A storage tank can help to even out water pressure fluctuations, providing a more consistent water flow.
Reduces strain on the softener: By providing a buffer, a storage tank reduces the strain on the water softener, potentially extending its lifespan.

However, consider these points:

Space requirements: Storage tanks can be large and require significant space.
Potential for contamination: Water stored in a tank can become contaminated if not properly maintained. Regular cleaning and disinfection are essential.
Cost: Storage tanks can be expensive to purchase and install.

Choosing the Right Storage Tank

If you decide that a storage tank is the right solution, consider these factors when choosing a tank:

Size: Choose a tank that is large enough to meet your peak water demand. A general guideline is to choose a tank that holds at least one day's worth of water usage.
Material: Choose a tank made of food-grade plastic or stainless steel. These materials are durable and won't leach harmful chemicals into the water.
Features: Look for tanks with features like a drain valve for easy cleaning, a level indicator to monitor the water level, and a vent to prevent pressure buildup.

Installation Considerations

Installing a soft water storage tank involves plumbing modifications and should ideally be performed by a qualified plumber. The tank needs to be properly connected to the water softener and your home's plumbing system. A backflow preventer is also essential to prevent water from flowing back into the water softener. Incorrect installation can lead to leaks, contamination, and damage to your plumbing system.

Maintenance

Regular maintenance is essential to keep your storage tank clean and prevent contamination. Here are some tips:

Clean the tank regularly: Drain and clean the tank at least once a year. Use a mild detergent and a brush to scrub the interior of the tank. Rinse the tank thoroughly with clean water.
Disinfect the tank: After cleaning, disinfect the tank with a solution of bleach and water. Follow the manufacturer's instructions for the correct concentration and contact time. Rinse the tank thoroughly with clean water.
Monitor the water quality: Regularly test the water in the tank for bacteria and other contaminants.

Conclusion

Deciding whether or not you need a soft water storage tank requires careful consideration of your household's water usage, the capacity of your water softener, and the performance of your well system (if applicable). By following the diagnostic steps outlined in this article, you can identify the underlying cause of your soft water problems and determine if a storage tank is the right solution. Remember to prioritize safety and consult with a qualified professional when needed. With the right approach, you can enjoy a consistent supply of soft water for years to come.
