Including filter system and high-performance Diquat filter.
Diquat is a herbicide used for vegetation control that can sometimes find its way into water through runoff or routine use. For Blocker homeowners, that can raise questions about bathing, cooking, and what’s used for pets and plants. Because diquat is usually present at low levels and has no distinctive taste or smell, testing is often required to know if it’s in your tap water. Installing treatment where water enters the house gives you ongoing protection and peace of mind for the whole family.
Contaminant levels can differ across neighborhoods, and Blocker is no exception — clear water isn’t always free of dissolved chemicals. Seasonal rains and local runoff can change what appears in source waters, so reviewing utility water quality reports and getting an independent test when you’re unsure are good first moves. From there, choosing a whole-house system lets you address concerns like diquat while keeping daily routines the same for showers, laundry, and cooking.
To reduce diquat in household water, a high-quality activated carbon filter is commonly the most effective single-filter option for broad chemical removal. Carbon adsorbs many organic compounds as water flows through and can also lessen other nuisance chemicals you might notice. In a whole-home installation for Blocker properties, it’s important to size the carbon media and flow rate so contact time remains sufficient during showers and when multiple taps run, instead of relying on small cartridges that can be overwhelmed.
Not all carbon filters perform the same, so design matters when targeting diquat. Using a catalytic or high-activity carbon media in a properly sized, backwashing carbon tank helps prevent channeling and clears trapped sediment that would otherwise reduce adsorption. This single-tank approach treats all the water entering a Blocker home, protecting fixtures and reducing what you might ingest, inhale as steam, or absorb through skin. Adding prefiltration where needed can help the carbon work more consistently and extend time between services.
