Len The Plumber, LLC. is a leading plumbing and drain company serving Central Maryland. Our certified professional plumbers are available same day to assist residential customers in Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Cecil County, Harford County, and Howard County. Our knowledgeable plumbers have years of experience dealing with a wide variety of plumbing issues including plumbing repairs, drain cleaning, water heaters, well systems, heating systems, sewer, water, and gas lines. We’re open 7 days a week with no extra charge on evenings or weekends!

"Our first encounter with Len the Plumber for gas boiler repairs went well and lead us to purchase a service contract with them for the 15% discount. However once we needed actual plumbing services and after they provided their "free" HVAC annual inspection it all went downhill rapidly. As others have noted the %15 discount is a concept they don't really honor. We were charged $1100 for less than 30 minutes of work for a repair that only required one cut and a simple joint (We had already removed the drywall and trim for access) and about $30 in parts (which by the way good luck getting an itemized bill from these people). On the HVAC side they broke what was a perfectly functioning 4 yr old AC HVAC and then wanted to charge $1200 to figure out how they broke it plus whatever parts they dreamed up needed replacing. They tried to claim the capacitor was bad. BTW - they brute force discharge the capacitors on units as part of their "maintenance check", something they should never do. We had BGE come out since their info was on the installation tag on the air handler and they diagnosed the issue in less than 30 minutes finding the thermostat had been burned up by mis-handling by the Len tech. They also said they never brutalize the capacitors the ways these guys do unless there is already a suspected issue with it. That's because the capacitor could be damaged by the way they handle it at Len the Plumber. So the "free" annual HVAC check cost me 3 days of discomfort and $250. Len refuses to admit wrong doing and will not reimburse us. They got $5000 in fees from us in less than a year so they don't care if we leave because they know another sucker is just around the corner waiting to be taken. These guys should lose their license given their business practices. Stay away from them at all costs."

FAQs for water treatment & purification system installation and replacement projects in Severn, MD

Water softeners consist of three main components: a mineral tank, a brine tank, and a control valve. In some smaller units, the mineral tank and brine tank are combined into one cabinet.

Professionals install whole-home systems at the point of entry of the main water line. Smaller units are installed under sinks or near a washer—these units only soften the water for that fixture, not the entire home.

  • Mineral Tank: Hard water passes into the mineral tank through resin beads, and an ion exchange occurs. Magnesium and calcium ions are exchanged for sodium or potassium ions from the brine tank.

  • Brine Tank: The brine tank contains sodium or potassium to recharge the resin.

  • Control Valve: The control valve determines when to clean the resin beads.

Choosing between a salt-based or potassium-based water softener depends on your priorities. Salt-based systems effectively remove hard-water minerals, regenerate efficiently, and are cost-effective. However, they may not be ideal for individuals on low-sodium diets. Potassium-based systems neutralize minerals without removing them and regenerate more frequently. They are more expensive but offer a healthier and more environmentally friendly option. If sodium levels are a concern and cost isn't a major factor, a potassium system may be the better choice.

To calculate your water softener's capacity, determine your grains per gallon (GPG) number by:

  • Multiplying the number of people in your home by 90. The average number of gallons used per person for washing, drinking, and cooking ranges from 80 to 100 gallons per day.

  • Multiplying that result by the hardness of your water. The average grains per gallon in the United States is 10 but can range from 0 to 17. You can find your GPG number by purchasing an at-home water testing kit.

Installing a water softener takes between two to four hours on average. The exact duration depends on the complexity of the unit and whether additional plumbing or electrical work is required. If modifications to existing pipes are necessary, installation may take longer. Preparing the installation area by clearing any obstructions can help streamline the process.

Water softeners can last up to 25 years with proper maintenance and care. The lifespan depends on the type and quality of the unit you choose. Single-tank electric water softeners may last around 12 years, while higher-quality models tend to last longer. Regular maintenance, such as routine inspections and timely replacement of salts or potassium, helps extend the life of your system. Most water softeners require minimal repairs over their lifespan.
