FAQs
What contaminants does a carbon filtration system remove from Harriman’s water supply?
High-quality activated carbon is extremely porous and adsorbs chlorine, chloramine, unpleasant tastes and odors, many volatile organic compounds (VOCs), pesticides, herbicides, some pharmaceuticals, and some PFAS compounds. While it is not designed to eliminate hardness minerals, dissolved salts, or biological pathogens, it is ideal for improving taste, smell, and the safety of municipal and well water in the Harriman area.
Why is carbon filtration recommended for homes and businesses in Harriman specifically?
Harriman’s municipal water is chlorinated to control bacteria, which can leave a strong taste and smell. In addition, runoff from the surrounding agricultural and industrial zones can introduce trace pesticides and VOCs. A carbon filtration system addresses these local water quality concerns by removing chlorine, reducing chemical by-products, and polishing the water, delivering crisp, clean-tasting water throughout the entire building.
How often do the carbon filter cartridges or media need to be replaced?
Replacement frequency depends on water usage and contaminant levels, but most whole-house carbon systems in Harriman need new cartridges every 6–12 months or a media bed replacement every 3–5 years. Our technicians check flow rate, chlorine breakthrough, and pressure drop during annual service visits and provide a clear schedule so your filter never loses effectiveness.
What is the difference between granular activated carbon (GAC) and carbon block filters?
Granular activated carbon (GAC) uses loose carbon granules that allow high flow rates and are common in whole-house systems. Carbon block filters compress finer carbon into a solid block, forcing water through small pores for longer contact time and superior removal of sediments and certain chemicals. For Harriman homes, we often pair a GAC pre-filter (high flow) with a carbon block post-filter (polishing) to maximize contaminant reduction without sacrificing pressure.
Can a carbon filtration system be installed on an existing plumbing setup, and how long does installation take?
Yes. Our licensed plumbers mount the filtration tank or cartridge housing on the main incoming water line—usually near the water heater or where the service line enters the building. A standard whole-house system takes 2–4 hours to install, requires only minor pipe modifications, and can usually be completed without shutting off water for more than 30 minutes.
What maintenance and warranty come with your carbon filtration systems?
Each system includes a 1-year workmanship warranty and a 5–10-year manufacturer’s warranty on tanks and housings. Routine maintenance consists of annual inspections, media or cartridge replacement as scheduled, and occasional sanitizing of the housing. We offer affordable service plans that handle all parts and labor, ensuring your Harriman water stays fresh and worry-free year after year.
