Water Filtration & Softeners
If you’ve ever noticed white crust on your faucets, spots on your glassware, or a faint chlorine smell coming from the tap, you’re not alone. A lot of Longmont homeowners deal with the same thing. That’s where professional water filtration comes in, and it’s exactly what our team at EP Plumbing helps folks with every week.
Longmont’s municipal water meets federal safety standards, but “safe” doesn’t always mean it tastes great or treats your plumbing kindly. Colorado’s mineral-rich groundwater and Front Range supply can leave behind hard water, scale, and disinfectant byproducts that many families choose to treat further.
Whether you live near Downtown Longmont, out by Union Reservoir, or in the surrounding Boulder County communities, EP Plumbing designs water treatment solutions around your home’s actual water quality, not a one-size-fits-all sales pitch.
Water Filtration Services Offered in Longmont

As a family-owned, locally based team, EP Plumbing handles the full range of water treatment needs, from a simple filter swap to a complete whole-home water treatment system. Below are the core services we provide throughout Longmont and the surrounding area.
Whole-House Water Filtration System Installation
A whole-house water filter treats water at the point where it enters your home, so every faucet, shower, and appliance gets cleaner water. That means better taste and odor at the kitchen sink, less sediment in your bathwater, and real protection for your plumbing.
Here’s how a whole-house system generally works:
Whole-house water filtration system installation in Longmont CO makes the most sense when you’re bothered by taste and smell throughout the home, dealing with visible sediment, or simply want to extend the life of your water heater, dishwasher, and washing machine. A whole house water filter is one of the best long-term investments in your plumbing.


Reverse Osmosis Drinking Water Systems

Reverse osmosis (RO) is a multi-stage filtration method that pushes water through a fine membrane to remove a wide range of dissolved impurities, giving you crisp, clean drinking water right at the tap.
A typical RO setup includes pre-filters, the RO membrane, a storage tank, and a dedicated drinking water faucet at your kitchen sink. Reverse osmosis system installation is popular for households that want better-tasting drinking water and coffee without buying bottled water.
RO systems do need routine care, filter and membrane replacement on a schedule, and we’ll walk you through exactly what yours needs.
Water Softener Installation and Repair
If hard water is your main headache, a water softener is usually the answer. We handle new water softener installation, replacement of aging units, and repairs when a system stops keeping up.
A water softener uses an ion exchange process to swap out the hardness minerals that cause scale. The result? Less buildup in pipes, a longer-lasting water heater, softer laundry, and fewer spots on your dishes and fixtures.


Choosing the Right Water Treatment System

So what’s the best water filter for Longmont hard water? Honestly, it depends. The ideal solution comes down to your home’s water quality, hardness level, household size, and what you’re trying to fix.
We always recommend professional water testing before buying equipment. Measuring hardness, chlorine, sediment, and TDS takes the guesswork out of it.
