Water Filtration

Cleaner, better-tasting water, matched to what’s actually in it.

Whole-house water filtration system with a UV unit installed in a garage

A water filtration system reduces chlorine, sediment and common contaminants, either for the whole house or at a single tap. AccuFlow installs whole-house carbon and sediment filtration and under-sink reverse osmosis systems in Lodi, Acampo and nearby towns. We start with your water: a water test tells us what’s in it, so the system fits the problem instead of a sales pitch. A whole-house system goes on the main water line and should be installed by a licensed plumber, since a poor install can affect pressure throughout the house.

Whole-House Filtration

Sediment and carbon filtration on the main line for every tap and shower.

Reverse Osmosis

Under-sink RO for drinking and cooking water, with a dedicated faucet.

Testing First

Systems chosen from your water test results.

Service & Repair

Filter changes, leaks, low output and failed membranes on existing systems.

Filter, softener, or both?

These solve different problems and get confused constantly. A filter removes chlorine taste and odor, sediment and certain contaminants. A water softener removes hardness minerals (calcium and magnesium) that cause scale. Some homes need both: a softener to protect fixtures and the water heater, and a filter or RO system for taste and drinking water. We explain what your test shows and which one, or both, actually helps.

Signs you may want water filtration

  • A chlorine taste or smell from the tap
  • A metallic taste or discolored water
  • Sediment in aerators or the toilet tank
  • You buy bottled water for drinking
  • Your home is on a private well
  • White buildup on fixtures (a softener sign)

Reverse osmosis for drinking water

An under-sink reverse osmosis system pushes water through a fine membrane and several filter stages, reducing a wide range of dissolved contaminants. It feeds a dedicated drinking-water faucet and often the refrigerator ice maker. We install it, show you how to change filters, and service the membrane and filters as they wear.

Water purification and RO system repair

Filtration and purification systems leak, lose output and stop working when filters clog or membranes fail. Water purification system repair starts with finding which part is actually the problem. We service whole-house filters, under-sink systems, UV units and reverse osmosis on most major brands, and if a system isn’t worth fixing, we recommend a lower-maintenance replacement.

On a reverse osmosis system, a slow drinking-water faucet usually comes down to a few causes: clogged pre-filters, a membrane past its life, a storage tank that has lost its air charge or has a ruptured bladder, or household water pressure too low for the membrane to work well (most RO systems want roughly 40 psi or more coming in). Sediment and carbon pre-filters are typically changed every 6 to 12 months and the membrane every 2 to 3 years, depending on your water and how much you use. Leaks usually trace to a cracked filter housing, a worn O-ring or a loose push-fit fitting, and a system that drains nonstop often has a failed automatic shutoff or check valve. Hard water already damaging fixtures? See water softeners.

What affects the cost of a filtration system

  • Whole-house or point-of-use: main-line filtration versus an under-sink system.
  • What’s in your water: the contaminants the system needs to handle.
  • Plumbing access: where the main line enters and space for the system.
  • Ongoing filters: replacement filter and membrane costs over time.

You get the price before we install, including what filters will cost to maintain.

A filter improves taste and removes contaminants; a softener removes hardness minerals. Some homes benefit from both, depending on their water. A water test tells you which.
An under-sink filter can be. A whole-house system goes on the main water line and should be installed by a licensed plumber.
White crust on faucets and shower heads, spotty dishes and soap that doesn’t lather well. A hardness test confirms it.
It depends on the system and your water. Sediment and carbon filters are often changed every few months to a year; RO membranes last longer.
It reduces a wide range of dissolved contaminants but isn’t a cure-all. Matching the system to your water test is what matters.
Yes. We repair leaks, low output, clogged filters and failed membranes on most major brands.
Usually clogged pre-filters, a worn-out membrane, low air pressure in the storage tank, or low incoming water pressure. Pre-filters are typically changed every 6 to 12 months and membranes every 2 to 3 years. We test each part and replace only what has failed.
