WSP Whole House Backwashing Filter, C-Series

When a plumber inspects your water line, one of the first things they might notice is sediment buildup that restricts flow and clouds your water. This kind of particulate contamination often causes taste and odor issues that simple filters can’t handle effectively over time.

What sediment and taste issues look like in your plumbing

When your water carries particles like rust, dirt, or organic matter, it can leave a visible film or sediment in pipes and fixtures. You might see an orange or brown tint in toilet tanks or notice a gritty residue on faucets and showerheads. These particles can cause your water to taste off, sometimes metallic or earthy. Over time, the filter media in basic systems may clog or compact, reducing flow and requiring frequent cleaning or replacement.

How the control head keeps your filter reliable and low-maintenance

The system uses a C-Series automatic control valve that manages cleaning cycles without your intervention. It periodically backwashes the media bed—that is, it sends water backward through the filter to lift and rinse away trapped particles. This process keeps the media from packing down or blinding off, which preserves flow and filtering capacity. The valve also has an air-draw feature that pulls in a pocket of air during backwash to help oxidize contaminants like iron and hydrogen sulfide without chemicals. Its 1.5-inch porting supports a higher service flow than smaller valves, helping maintain water pressure during peak use.

Why catalytic manganese-dioxide media suits your water problem

Inside the tank, catalytic manganese-dioxide media targets iron, manganese, and hydrogen sulfide. These are common sources of unpleasant taste, odor, and staining. This media works by encouraging a chemical reaction that changes these dissolved minerals into solid particles that the filter can trap. Because it’s specially designed for these contaminants, it’s more effective and longer-lasting than generic media types you might see in off-the-shelf filters.

The tank and capacity designed for a typical family home

The system comes with a sturdy pressure vessel designed to hold the media securely and withstand household water pressure. While specific tank dimensions depend on your individual setup and water conditions, it is sized to handle flow rates of about 10 gallons per minute. This makes it suitable for average family homes with three to four people and two to three bathrooms, supporting everyday water needs without bottlenecks.

Who this filter fits and when you might need a different size

This backwashing filter is well matched to moderate usage homes experiencing particulate-related taste or staining problems. If you have a larger household, more bathrooms, or higher water demand, you may want to consider a system sized to handle greater flow rates to avoid reduced pressure during peak times. Conversely, for smaller households or lighter water issues, a smaller system might be more economical and easier to maintain.

What you receive with your system and how to move forward

This package includes the pressure vessel covered by a lifetime warranty, giving you long-term assurance on the tank itself. The control valve and electronics carry the manufacturer’s standard warranty terms. A bypass valve is included, letting you isolate the filter for service without shutting off water to your home—something many competitors sell separately. You’ll also get 10 feet of discharge hose, ready to connect for drain line backwash water. Because every setup is unique, we confirm the exact tank size and configuration when we size your system.

We'll need your water problem details and ZIP code to make sure the system fits your home precisely and provide you with pricing.

Who this size is right for

This is rated for roughly 10 gallons per minute of service flow, which suits an average family home - around 3-4 people with 2-3 bathrooms.

Check this against your peak demand rather than your daily total. A unit that is marginal on flow will drop pressure at exactly the times you notice it most.
