Why You Need a Water Softener

Hard water contains high levels of minerals such as calcium and magnesium. These minerals can wreak havoc on your home’s plumbing system and daily comfort. Over time, they build up inside pipes and appliances, reducing water flow and efficiency.



Here are some common signs of hard water:


  • White residue or scale on faucets and showerheads
  • Spots or film on dishes and glassware
  • Stiff, scratchy laundry and faded colors
  • Dry, irritated skin and dull hair
  • Reduced water pressure and appliance efficiency


A water softener system removes those excess minerals, providing clean, soft water that feels better, looks clearer, and performs more efficiently. With professional installation and regular maintenance from Castlewood Plumbing, you can protect your home from hard water damage and enjoy lasting comfort.

Even the best water softeners may need repairs from time to time. If you notice signs of hard water returning or your system is not regenerating properly, our expert plumbers are ready to help.


We provide fast, accurate water softener repair services for all brands and models. Our service vehicles are fully stocked, allowing us to complete most repairs the same day.


Common issues we fix include:

  • Salt bridges or blockages in the brine tank

Regular maintenance is essential to keeping your water softener running efficiently. Over time, mineral deposits and salt buildup can reduce your system’s performance. Routine service helps prevent unexpected breakdowns and extends the lifespan of your equipment.



Our maintenance services include:

  • Checking salt levels and refilling as needed
  • Inspecting resin tanks and valves
  • Cleaning and flushing the system

Water Softener Replacement

If your water softener is over ten years old or no longer keeping up with your household’s needs, it may be time for a replacement. Modern systems are more energy-efficient, require less salt, and use less water.



We make replacement simple. Our team will assess your old unit, remove it safely, and install a new, high-performance model that fits your home and budget. The result is better water quality, lower maintenance, and improved efficiency.

The Benefits of Soft Water

Soft water does more than prevent scale buildup. It also improves your home’s comfort, efficiency, and long-term value. Here are some of the most noticeable benefits you will experience after installing a water softener:

  • Cleaner Plumbing and Fixtures: No more limescale on faucets, sinks, and shower walls.
  • Softer Laundry: Clothes stay brighter, softer, and feel better on your skin.
  • Healthier Skin and Hair: Soft water helps prevent dryness and irritation.
  • Longer Appliance Life: Reduces mineral buildup in water heaters, dishwashers, and washing machines.
  • Lower Energy Bills: Soft water allows your systems to run more efficiently, saving you money each month.

Frequently Asked Questions

  • How long does it take to install a water softener?

    Most installations can be completed within a few hours, depending on your plumbing layout and the type of system you choose. Our plumbers work efficiently to minimize disruption to your day.

  • What is the best type of water softener for my home?

    The best system depends on your water hardness, home size, and budget. We perform an on-site water test and recommend a system that meets your specific needs for performance and efficiency.

  • How often should I check the salt level in my softener?

    Check your salt level at least once a month. Keeping the tank at least one-third full helps maintain proper regeneration and ensures consistent soft water.

  • Can my old water softener be repaired, or do I need a new one?

    In many cases, minor issues can be repaired. However, if your system is more than ten years old or requires frequent service, replacement may be a more cost-effective solution. Our plumbers will provide honest recommendations based on your situation.

  • Will a water softener affect my water pressure?

    A properly installed and maintained system should not reduce your water pressure. If you notice changes in pressure, it could indicate a clog or buildup that our team can easily resolve.
