Water Softener Installation — Edgewater, MD
An Edgewater homeowner had hard water causing scale buildup on fixtures, reduced water heater efficiency, and soap that would not lather. Water test showed hardness at 18 gpg — very hard. We installed a 48,000-grain water softener sized for their household demand.
The Problem
An Edgewater homeowner contacted us about hard water problems. They had significant scale buildup on all fixtures and shower doors, their water heater was only 4 years old but already showing reduced efficiency, and soap and shampoo would not lather properly. A water test confirmed hardness at 18 gpg — classified as very hard. At that hardness level, scale buildup is aggressive and water heater efficiency loss is measurable.
Our Diagnosis
Hardness at 18 gpg required a properly sized water softener. We calculated the household demand: 4 people × 75 gallons/day × 18 gpg = 5,400 grains/day. A 48,000-grain softener regenerating every 9 days was the appropriate size. We also noted iron at 0.8 ppm — within the range that a softener with an iron-capable resin could handle without a separate iron filter.
The Repair Process
- 1Comprehensive water quality test — hardness 18 gpg, iron 0.8 ppm, pH 7.2
- 2Sized 48,000-grain softener for 4-person household at 18 gpg
- 3Selected iron-capable resin to handle 0.8 ppm iron without separate filter
- 4Installed softener at point of entry, bypassing outdoor hose bibs
- 5Set regeneration cycle for every 9 days based on calculated demand
- 6Programmed salt dose for efficient regeneration
- 7Post-installation test confirmed hardness below 1 gpg from all indoor fixtures
The Outcome
Hardness reduced from 18 gpg to below 1 gpg. Scale buildup stopped immediately. Homeowner reported that existing scale on fixtures dissolved within 2–3 weeks. Soap lathers normally. Water heater efficiency expected to recover as scale in the tank dissolves.
Key Takeaway
Water softener sizing matters. An undersized softener regenerates too frequently and wastes salt; an oversized softener regenerates too infrequently and allows hardness breakthrough. Proper sizing is based on household size and water hardness — not just a generic "whole-house" label.

"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."
