GPM is gallons per minute, the peak amount of water your system can supply at once without a drop in pressure. For softeners it also sets the grain capacity between regenerations. Sizing it to your home keeps full pressure at every tap and the right capacity for your water.

Match it to your number of bathrooms and the fixtures likely to run at the same time. As a rule of thumb: 10 GPM suits 1 to 2 bathrooms, 15 GPM suits 3 to 4, and 20 GPM suits 4 or more. A shower uses about 2.5 GPM. Every flow-rate product page has a "Which flow rate is right for you?" section with the details.

Pressure drops when several fixtures run together, a softener regenerates too often and wears its resin faster, and a filter's media exhausts sooner. When you're between sizes, it's better to size up.

It's how much hardness a softener removes before it needs to regenerate, measured in grains. Larger systems hold more resin and more capacity, so they regenerate less often. For example, a 10 GPM softener is about 35,000 grains, 15 GPM about 53,000, and 20 GPM about 70,000.

Because no two wells are alike and what's in the ground is what comes out of your tap, with no city treatment in between. Iron, manganese, sulfur, hardness, sediment, tannins, nitrates, and bacteria can all appear in different combinations. A water test is the only way to know what to treat.

The iron filter goes first. Removing iron and sulfur before the softener protects the softening resin from fouling and keeps both systems working longer. Order matters on well water, which is why we design the sequence around your test.

It's hydrogen sulfide, a dissolved gas. Air-injection and advanced-oxidation systems oxidize the gas and filter it out, with no chemicals to buy or refill.

Acidic well water keeps iron dissolved, so it slips through the filter. A backwashing pH neutralizer raises the pH first, so the greensand media can capture and remove the iron at full efficiency. See iron & manganese systems →

Yes. Well water varies from property to property, and iron type, sulfur level, hardness, pH, and contaminants all change the design and sizing. Testing means you treat what you actually have.

It removes chlorine, chloramine, taste, and odor across the whole home, so every shower, tap, and appliance gets cleaner water. Our backwashing filters clean themselves, so there are no cartridges to change.

Yes. Chloramine is harder to remove than plain chlorine, and catalytic carbon is the media designed for it. If your city uses chloramine, choose a catalytic carbon filter rather than standard carbon.

Whole-house backwashing carbon media typically lasts 5 to 10 years depending on your water and use. Because the filter backwashes itself, there are no cartridges to swap in between.

It catches sand, silt, and rust before they reach your fixtures and the systems downstream. It's the foundation of most setups, protecting softeners, filters, and RO from grit and extending their life.

Check three things first: that the brine tank has salt, that the bypass valve is in the "service" (not bypass) position, and that the system is regenerating on schedule. If all three are fine, the softener may be undersized for your hardness, contact us and we'll check the numbers.

The most common causes are a clogged sediment prefilter, a bypass or valve set incorrectly, or a system sized below your peak demand. Replacing or cleaning the prefilter and confirming the valve position resolves most cases.

Salt use is tied to your hardness setting and household size. If the settings don't match your actual water and usage, the system regenerates too often or not enough. We can help you dial in the program.

On air-injection systems, the air pocket that oxidizes the sulfur can need a refresh, and the media and pH should be checked. If the smell returns quickly, the system may need servicing or a pH neutralizer ahead of it.

Both are usually a sign the filters or membrane are due for replacement, or that feed pressure is low. Replace the filters on schedule and check your incoming pressure. Still stuck? Reach out and we'll walk through it.
