Looking for a water softener or filtration system in Northern Virginia? Leonard Splaine tests your water and installs softeners, whole-home filters, reverse osmosis, and UV systems for cleaner, safer water.
Why us?
Serving Northern Virginia
Northern Virginia water is hard, and on well systems it can carry iron, sediment, and bacteria. That shows up as scale on your fixtures, spots on your dishes, dry skin, and a shorter life for every water-using appliance in the house. We test your water, explain what's actually in it, and install the right fix: a water softener for hard water, whole-home filtration for sediment and chlorine, reverse osmosis for clean drinking water, and UV purification to kill bacteria on well systems.
Water treatment is an easy thing to oversell, which is exactly why we test before we recommend anything. Leonard Splaine is run by the third generation of the same family, and a name built in this community over decades is worth more to us than one padded invoice. If the test says you only need a softener, that's all we'll suggest.
Questions about your water reach a person: we pick up around the clock. Describe what you're seeing, spots on glassware, odors, scale on fixtures, and we'll get a water test scheduled, often for the same day.
Our Services
Testing, softening, filtration, and purification for cleaner water across Northern Virginia.
We don't sell you a system before we know what's in your water. We test for hardness, chlorine, iron, sediment, pH, and on wells, bacteria, then walk you through the results in plain English and recommend only what your water actually needs.
Northern Virginia water is hard, and hard water scales up pipes and water heaters, spots your dishes, and dries out skin and hair. A water softener protects every water-using appliance in the house and makes soap and shampoo actually lather. We size and install it right.
A whole-home filter on your main line takes out sediment, rust, chlorine, and odor before the water ever reaches a faucet. Cleaner water at every tap and shower, less wear on your fixtures and appliances, and no more chlorine smell.
For clean drinking and cooking water, we install under-sink reverse osmosis systems that strip out dissolved solids, lead, and other contaminants down to the molecule. Bottled-water quality straight from a dedicated faucet, without the plastic.
On well water, bacteria and viruses are a real concern. A UV purification system disinfects your water with ultraviolet light as it flows through, no chemicals, no taste, killing the microorganisms a filter alone can't catch.

Lynn Gilbertson Google review Kyle provided emergency holiday weekend service when our a/c was completely out with 104F "feels like" temperatures. He quickly diagnosed and fixed our system, with solutions for avoiding similar problems in the future. We are grateful to Kyle and Leonard Splaine!
Katie Kada Facebook recommendation Couldn't have asked for better service! Leonard Splaine was timely, honest and did a wonderful job replacing our very outdated AC unit. We plan to use them again for any service or replacement in the future and we'll recommend them to our friends and family.
I will definitely use this company again! Our AC went out on one of the hottest days of the year. They answered and came to the rescue! Family owned and very kind. Technician was knowledgeable and quick.
Ankur Mundra Facebook recommendation I've used Leonard Splaine the last 5 years. They are professional, provide quality service, and answer my questions and concerns. Michael Ford came out this year to do my spring maintenance as well as eztrap installation and condenser coil cleaning. He did an excellent job.
Candace Bond Google review They were such gentlemen and seemed to be very knowledgeable and honest. They were also very patient and took the time to answer all of our questions. I would highly recommend these guys.
A/C stopped working on the hottest day of the year, so far. They came over the same day and had it up and running in no time. The price was reasonable and the tech was great.

Good questions
The questions Northern Virginia homeowners ask us most about water quality systems. Anything else, the phone's faster than the internet.
Yes, much of the area has moderately hard to hard water, and many homes on wells deal with iron and sediment too. A quick water test tells us exactly what you have so we can recommend the right fix.
If you see scale on faucets, spots on glassware, soap that won't lather, or you're replacing water heaters often, hard water is the likely culprit and a softener will help. We test first so you're solving a real problem, not a guessed one.
Whole-home filtration cleans all the water in the house of sediment, chlorine, and odor. Reverse osmosis is a finer, under-sink system for drinking and cooking water that removes dissolved solids and contaminants. Many homes use both.
Always. We won't sell you a system you don't need. We test your water, show you the results, and recommend only what it actually calls for.
Yes. Well water often needs iron and sediment filtration plus UV purification to handle bacteria. We test, explain what we find, and build a system that makes your well water safe and clean.
