How do I choose the best water filtration system for arsenic?
The best water filtration system for arsenic is the one selected after a certified lab water test confirms your arsenic level and type, then matched to those results. Most decisions hinge on whether you want only drinking water treated at one tap or every fixture in the home, plus how much maintenance you’re willing to do. Reverse osmosis is a common point-of-use option for drinking water, while whole-home solutions…
What Is The Average Maintenance Cost For A Water Purifier?
The average maintenance cost for a water purifier is not a single set price; it depends on the system type and the service work needed. The most common driver is routine filter media or cartridge replacement, which varies by design and water quality.
Which way should a water filter be installed?
A water filter should be installed with the flow arrow on the housing pointing in the same direction as your home’s water flow. Most problems happen when the inlet and outlet get reversed, which can restrict pressure and reduce filtration performance. Use the cold-water line for drinking-water filters, and tighten fittings evenly to avoid leaks. Our licensed plumbers install and maintain whole-home filters,…
What should I do if my water filtration system stops working?
If your water filtration system stops working, put it in bypass to restore basic water flow, then check power (or GFCI), system shutoff valves, and any error lights before using filtered water again. The most common cause is a clogged prefilter or an RO postfilter that needs replacement; softeners often stop treating when salt is low or a regeneration is overdue. Our licensed plumbers support systems in and around…
What water filtration system filters can remove Cryptosporidium?
Water filtration systems that remove Cryptosporidium include reverse osmosis (RO) drinking-water units, UV disinfection systems, and filters specifically certified for cyst reduction. Cryptosporidium is a chlorine-resistant parasite, so effective control relies on very fine membranes, targeted disinfection, or both rather than standard taste-and-odor filters.
Do Water Filtration Systems Remove Giardia From Drinking Water?
Water filtration systems can remove or reduce Giardia when the system is rated for microbiological (cyst/parasite) reduction, such as reverse osmosis paired with a disinfection step or a fine-micron filter designed for cysts. Most problems occur when a basic taste-and-odor carbon filter is mistaken for a health-grade filter that targets organisms. We install whole-home and point-of-use solutions and often help…
How Often Should You Replace A Water Filter Cartridge?
You should replace a water filter cartridge according to the manufacturer's schedule, which varies by filter type, your water quality, and how much water you use. Most replacements are driven by the filter reaching capacity or clogging with sediment, which causes flow loss and poorer taste. Follow the system's manual for timing; RO prefilters and carbon cartridges differ from whole-home sediment or specialty…
Why Is My Water Filter Leaking From The Top?
A water filter leaking from the top usually means the seal between the head and the housing isn’t tight or system pressure is forcing water past it. The most common trigger is a disturbed or worn upper seal after a cartridge change. Less often, misalignment or a cracked cap lets water track along threads and appear at the top. Our plumbers routinely resolve these issues for homes around Tuscola. A telltale…
Can I install a water filter myself safely at home?
Yes, many faucet-mounted and pitcher water filters are safe DIY projects, but under-sink reverse osmosis and whole-home filtration are best handled by a licensed plumber. The most common DIY issue is a slow leak from a loose fitting or misaligned seal that quietly damages cabinets or walls. Our team regularly installs whole-home filtration, reverse osmosis, and softeners across the Champaign area with the right…
What Are The Common Problems With A Whole House Water Filter?
Common problems with a whole-house water filter are flow restriction, declining water quality, leak points at the housing, and media wearing out faster than expected. Most issues come from a clogged or overdue cartridge that chokes water flow. Other causes include exhausted filtration media, undersized equipment, or installation mistakes; a brief inspection usually pinpoints the source. Across the Savoy area, we…
Do Water Filtration Systems Require Regular Maintenance At Home?
Yes, home water filtration systems do require regular maintenance to keep water quality high and equipment working efficiently. Most often, salt‑based water softeners need annual service to stay efficient, while whole‑home filters and drinking‑water systems benefit from periodic checkups to protect plumbing and appliances. Our team also installs high‑efficiency options like the Novosoft 485HE; its precision brining…
How much does a whole house water filter installation cost?
Whole-house water filter installation cost is not one-size-fits-all; Lanz provides a firm price only after an in-home evaluation. The biggest swing usually comes from how much filtration your home needs to keep strong water pressure and flow. Our technicians size equipment using on-site water tests so the filter cleans well without choking fixtures. We regularly design and install whole-home filtration for families…
