Water Softener Installation — Prince Frederick, MD

A Prince Frederick homeowner was going through soap and detergent at twice the normal rate and had scale buildup on every faucet. We tested the water at 18 GPG hardness and installed a properly-sized water softener — immediate improvement in lather and scale.

The Problem

A homeowner in Prince Frederick called us after noticing white scale deposits building up on their faucets, showerheads, and glass shower doors. They were also going through dish soap, laundry detergent, and shampoo much faster than expected. Their water heater had been making a popping noise — a sign of scale buildup on the heating elements.

Our Diagnosis

We tested the water hardness on-site: 18 GPG (grains per gallon) — classified as very hard. The national average is 10 GPG; anything above 7 GPG causes visible scale. At 18 GPG, scale was building up rapidly on all fixtures and inside the water heater. We also confirmed the water heater's lower heating element had significant scale coating — reducing efficiency and shortening the element's life. A properly-sized water softener was the correct solution.

The Repair Process

  1. 1Tested water hardness: 18 GPG confirmed — very hard water
  2. 2Calculated household water usage to size the softener correctly
  3. 3Recommended and installed a 48,000-grain Fleck 5600SXT water softener
  4. 4Installed bypass valve for outdoor hose bibs (softened water not needed for irrigation)
  5. 5Set regeneration cycle based on household water usage — optimized salt efficiency
  6. 6Connected brine tank and filled with solar salt
  7. 7Ran system through initial regeneration cycle — confirmed proper operation
  8. 8Tested water hardness at kitchen faucet after regeneration: 0 GPG

The Outcome

The homeowner noticed softer water immediately — better lather in the shower, dishes coming out of the dishwasher without spots, and laundry feeling softer. The scale on faucets and showerheads began dissolving within two weeks. The water heater's popping noise stopped after the first month as the existing scale softened and flushed out.

Key Takeaway

Hard water above 10 GPG causes significant damage to water heaters, appliances, and plumbing over time. A properly-sized water softener pays for itself in reduced appliance wear, lower soap usage, and extended water heater life.

"We recently had Deep Dive Plumbing Maryland out to our home in Annapolis after we suddenly started noticing sewer flies throughout the house. They truly lived up to their name and performed a full "deep dive" diagnostic inspection instead of just treating the symptom. During their inspection they discovered our sewer pipe connected to the toilet had been leaking into the basement for quite some time. The team explained everything clearly, provided upfront pricing before starting any work, and even gave us a military discount which was greatly appreciated. They were professional, respectful, extremely knowledgeable, and took the time to make sure the repair was done correctly."

"Great service with knowledgeable and neat professionals. Highly recommend! Deep Dive Plumbing helped with my bathroom project, including reinstalling a pedestal sink after new flooring was installed and addressing a toilet issue that had been causing constant clogs. The team was professional, courteous, and took the time to make sure everything was completed correctly. Their attention to detail and cleanliness really stood out. I am very happy with the results and would not hesitate to call them again."
