Water Filtration Installation in the DC Metro Area
The water coming into a home carries more than water. Around the DC metro area, mineral-heavy hard water, chlorine, and sediment ride along in the supply — and they don’t just change how the water tastes. They build up inside your pipes, your water heater, and your fixtures, a little at a time, for years.
Custom Flow Plumbers installs whole-house water filtration for homeowners across the DC metro area — systems plumbed in where the water enters the home, so every faucet, shower, and appliance downstream gets treated water.
What untreated water does to a home
- Scale buildup in the water heater — mineral crust insulates the heating surfaces, so the heater works harder and wears out sooner
- Crusty, stiff fixtures — faucets, showerheads, and valves that clog, drip, and get hard to turn
- Sediment through the system — grit that clogs aerators and collects in appliances and toilet tanks
- Stains and spots — mineral marks on fixtures, sinks, and tubs that keep coming back no matter how often they’re cleaned
- Chlorine taste and smell in the water you drink and cook with
None of that shows up all at once. It’s slow damage — the kind that’s cheaper to stop than to repair.
What we install
Whole-house filtration installed at the main line, sized to your home — filter housings and treatment equipment plumbed in where the water comes in, before it reaches anything else in the house. One system, treating the water for the whole home instead of one faucet at a time.
For drinking water specifically, we also install reverse osmosis systems — under-sink units that give you a dedicated tap of highly filtered water for drinking and cooking, on top of what the whole-house system does.
And filtration doesn’t have to be whole-house to be worthwhile. Shower heads with built-in filtration take the chlorine and mineral edge off the water you bathe in — a smaller step that makes a daily difference, and one we can add to any home.
If you’re not sure what your home needs, that’s the normal starting point. We can test your water, look at your plumbing, and recommend the setup that fits — no more system than the house calls for.
How we handle it
- Look first — and test the water. We check the home’s plumbing, test what’s actually in your water, and talk through what’s bothering you — taste, stains, scale, all of it. The recommendation is based on your water, not a guess.
- Recommend and explain. The system we’d install, where it goes, and what it does — in plain language, before any work starts.
- Install it right. Plumbed into the main line with shutoffs, so the system can be serviced without shutting the whole house down blind.
- Walk you through it. How the filters change, how often yours need it, and what to watch for — you leave knowing your own system.
FAQ
Q: Is whole-house filtration different from a faucet or pitcher filter?
A: Yes. A faucet filter treats one tap. A whole-house system treats the water where it enters the home, so it also protects the plumbing itself — the water heater, the pipes, and every fixture — not just the taste of a glass of water.
Q: Will filtration actually help my water heater?
A: Mineral scale is hard on water heaters — it builds up on heating surfaces and inside the tank, and the heater pays for it in efficiency and lifespan. Cutting the mineral load in the water is one of the simplest ways to be kinder to the equipment you already own.
Q: How do I know what my water actually needs?
A: We test it. A water test shows what’s in your supply — minerals, chlorine, sediment — so the system we recommend is matched to your water instead of sold off a shelf. If your water turns out to need very little, we’ll tell you that too.
Filter changes, well water, and taste
Q: How often do the filters need changing?
A: It depends on the system and how much water your household uses. When we install yours, we’ll tell you the change schedule for that system and show you how it’s done — it’s straightforward. And if you’d rather not think about it, call us and we’ll take care of the filter changes for you.
Q: My home is on well water. Is this still for me?
A: Well water has its own set of issues — sediment especially — and filtration is commonly part of keeping a well system healthy. Tell us what you’re seeing and we’ll look at what your water needs.
Q: I only notice the taste. Is a whole system worth it?
A: If taste were the only issue, a point-of-use filter might be enough — we’ll say so if it is. But most homes that notice the taste also have the scale and sediment that come with the same water, and that’s where whole-house treatment earns its keep.
