When something goes wrong with your plumbing, you want someone local who picks up the phone and actually shows up. That's been Simpson Plumbing & Filtration's job: your plumber in Vancouver, WA since 1981. We're family-owned, we've fixed just about everything a house can throw at us, and we treat your home the way we'd want ours treated.
These days, we're known for two things: dependable plumbing repair and being Vancouver's go-to for whole-house water filtration. Here's how we help with both.

Here's something a lot of people don't know until they ask: Simpson Plumbing & Filtration has become one of the area's leading names in whole house water filtration installation.
City water in Vancouver is safe, but "safe" and "great-tasting" aren't the same thing. Chlorine and chloramine, used to disinfect municipal water, are often what's behind that faint chemical smell or flat taste from your tap. A whole house water filtration system treats water as it enters your home, so every faucet, shower, and appliance benefits, not just the one sink where you might have tried a pitcher filter before.
A typical water filtration system includes:
We also offer salt free treatment options for homes dealing with hard water, so you get better water quality without adding sodium to the mix. Whether you're looking at a water filtration system installation for the first time or upgrading an older setup, we walk you through what your specific home actually needs, not just what's most expensive.

Most calls we get are simple, if frustrating: a leaking pipe, a water heater on its last leg, low pressure that's been bugging you for months. Whatever it is, we show up with a clear, upfront price before we start, not a surprise at the end.

“10 out of 10. Amazing work done by Alex. He was on time, very knowledgeable, friendly, funny and went above and beyond to make sure we were happy every step of the way! Excellent communication with what he was doing and making sure we understood what was happening! Simpson Plumbing replaced our water heater 2 years ago and a broken/leaking pipe today in the basement. They will always be our go to people!!!” - Steve Heckman

Do you offer same-day plumbing service in Vancouver, WA?
Yes, we offer same-day service when available for urgent plumbing needs. Call us, and we'll let you know as soon as we can get to you.
How do I know if I need a water filtration system or a water softener?
It depends on your water. Filtration addresses taste, odor, and chlorine. Softening addresses hardness from minerals like calcium and magnesium. Many Vancouver homes benefit from both, and we're happy to talk through what your home actually needs.
Is whole-house water filtration a big installation project?
Not usually. Most systems connect to your home's main water line and are installed in a matter of hours, without major plumbing rework.
Are your plumbers licensed and insured?
Yes. Every plumber on our team is fully licensed and insured, and we've held that standard since 1981. You can count on the work being done right the first time.
