Sediment Filtration Systems
Sediment Filtration Systems in Marin, Sonoma & Napa County
When it comes to water quality, most homeowners rarely give a second thought to what’s coming out of the tap. But sediment, such as sand, silt, dirt, and rust, can make its way into your water supply, leading to a variety of issues that affect your plumbing, appliances, and even your health.
Sediment buildup doesn’t just compromise the taste and clarity of your drinking water, it can also clog faucet aerators, reduce water pressure, and shorten the lifespan of your appliances and water heater. If you’re noticing tiny particles of sand, soil, or grit coming from your faucets, it’s time to consider installing a sediment filtration system. That’s where we come in.
At Ongaro & Sons, our seasoned professionals bring years of experience in the water treatment industry. We proudly serve Marin, Sonoma, and Napa counties, along with nearby the North Bay communities, offering expert solutions in sediment filtration, as well as other water treatment services including reverse osmosis, UV purification systems, and water softeners.
What Is Sediment Filtration?
Sediment filtration is the first line of defense in a whole-home water filtration system. These filters are specifically designed to trap and remove suspended solids and particulate matter from your water supply. Over time, sediment buildup can corrode pipes, wear down water-using appliances, reduce water pressure, and leave your water looking cloudy or discolored.
A properly installed sediment filter prevents these issues and helps extend the lifespan of your plumbing system.
Why Choose Sediment Filtration for Your Home?
Installing a sediment filtration system comes with several important benefits, including:
- Cleaner, Safer Water: By removing visible and invisible particles, a sediment filter gives your family cleaner water that’s safer to drink, cook with, and bathe in.
- Protects Your Plumbing: Sediment acts like sandpaper inside your pipes, wearing them down over time. Filtering it out helps prevent corrosion, leaks, and blockages.
- Extends Appliance Lifespan: Water heaters, washing machines, and dishwashers can all suffer from sediment buildup. A filtration system keeps these essential appliances running longer and more efficiently.
- Improves Taste and Appearance: Clear, sediment-free water doesn’t just look better, it tastes better, too. You’ll notice a difference right away in everything from drinking water to your morning coffee.
- Reduces Maintenance and Repairs: Less sediment means fewer service calls and a reduced risk of expensive emergency plumbing repairs caused by clogs or internal damage.
All work is performed under active California contractors license #215233.
Common Signs You Need Sediment Filtration
Not sure if you need a sediment filter? Here are a few signs to watch for:
- Cloudy or gritty tap water
- Visible particles in your glass
- Rust-colored stains in your sinks or tubs
- Reduced water pressure throughout the home
- Frequent clogs or maintenance issues with appliances
If you’ve noticed any of these issues in your home, it might be time to consider a professional sediment filtration solution.
Installing a Sediment Filtration System
Although sediment often is easy to detect in tap water, testing also will identify other contaminants in your water. Our qualified professionals will test your water and send samples to a third-party lab. The results will help us determine which water treatment system is best for your home.
Identifying Sediment Filtration Placement
Ongaro & Sons takes a whole-home approach to filtering sediment from your water supply. We install the appropriate sediment filters where your water enters your home, blocking particles before they reach your water heater or faucets.

Repairing and Maintaining Your Sediment Filtration System
If anything goes wrong with your sediment filtration system, or if it is not working as well as it should, call us at Ongaro & Sons for an assessment. You might benefit from installing a second sediment filter at your kitchen faucet or an additional water treatment system, such as a water softener or reverse osmosis device.
Regular maintenance is a must to keep the filter working properly. A clogged filter can affect water pressure and reduce its ability to remove sediment. Check your sediment filter for excessive accumulation of rock, silt, and other particles every couple of weeks. Filter capacity, the amount of water you use, and the amount of sediment in your system determine how long the filter lasts.
If you prefer, Ongaro & Sons can handle the maintenance of your water treatment system.

Can sediment filtration improve water taste and odor?
Sediment filters are primarily for removing visible particles. To improve taste and odor, they’re often paired with activated carbon filters or reverse osmosis systems, which target chlorine and other chemical contaminants.
Is sediment filtration necessary if I already have a water softener or RO system?
Yes. Sediment filters are essential even with a softener or reverse osmosis system. They act as a pre-filter, protecting more sensitive systems from clogging or premature wear caused by particulate matter.
