Should I Repipe with Copper or PEX in Federal Way?

It often begins with little annoyances. A small leak under the sink. A pipe in the basement patched more than once. Rust-colored water filling your glass. Showers that don’t feel as strong as they used to. After a while, the thought creeps in: maybe it’s not just the pipes—it’s the whole system. That’s when many Federal Way homeowners find themselves asking the same question: if I repipe, should I choose copper or PEX?

It can feel like a big decision, but you don’t have to figure it out on your own. At 2 Sons Plumbing Federal Way, we’ve guided countless families through this exact choice, and we’re here to make the process simple and stress-free.

Copper vs. PEX: What’s the Difference?

Both materials are excellent, but they offer different strengths:

PEX piping – Flexible, affordable, and easy to install. It resists freezing, bends around corners, and doesn’t corrode. For many homes, it’s the practical and budget-friendly option.
Copper piping – Rigid, durable, and heat-resistant. Copper has been trusted for decades and can last a long time, though it’s more expensive and can be affected by water chemistry.

In short: PEX saves money and works well for most homes. Copper offers long-term strength but comes with a higher cost.

Why Repiping Isn’t DIY

Changing a faucet washer or swapping a short section of pipe is one thing. Replacing every pipe in your home is something else entirely. Repiping involves running lines behind walls, through ceilings, and under floors. One mistake could lead to leaks, damage, and costly repairs.

That’s why repiping is never a DIY job. It’s a major investment in your home’s safety, and having it done by licensed professionals ensures your new system is reliable for years to come.

Signs You May Need to Repipe

Not sure if it’s time? Here are the most common signs:

Leaks that keep coming back
Rusty or discolored water
Weak water pressure throughout your home
Old galvanized steel pipes still in place

If you’ve noticed any of these, it’s worth getting your plumbing inspected.

What It Might Cost

The cost depends on your home’s size and which material you choose. On average, Federal Way homeowners can expect:

PEX repiping: $6–$12 per square foot
Copper repiping: $10–$18 per square foot

PEX usually saves money upfront, while copper may provide added value in longevity. Either way, we’ll give you clear, upfront pricing before any work begins.

Our house decided to replace our own toilet, but we got stuck halfway through because we didn’t have the right tools and accidentally broke an anchor bolt. I called 2 Sons Plumbing, and they showed up within an hour to help us out. Derek, our plumber, was super friendly, explained everything clearly, and got the job done quickly and professionally. Excellent service all around—highly recommend!

Dave and David came and cleared out a huge clog in my kitchen sink (both sides) that has been plaguing us for a while as well a ton of glass shards that got into the drain when our glass fridge shelf broke. Dave walked us through each step of the process and explained everything which was excellent. He also gave us advice about galvanized piping replacement. They even gave us a few free parts for the sink drain that had eroded away and didn’t charge extra for it!! All around 5 star service!!!

Fantastic service and communication. Local company. Solved my clogged basement laundry utility sink. Dave and David were courteous, informative, professional and easy to engage with. Scheduling was easy (they came the next day) and they arrived within the expected time window. Transparent pricing and i could also apply a coupon. I will use them again.

Great service and Dave their plumber is the best. We have an odd house with even odder plumbing. The pipes are a mess of grandfathered-in open air nonsense, when our pump started making some noises (and a little leaking) after some DIY heat tape adventures (getting ready for colder weather), we were worried that we would need a massive repair but Dave came and looked at it and immediately realized we had unplugged the float plug from the pump plug which was 90% of the problem and the leak just need a little tightening of a flex joint. The company was quick and didn't charge for an estimate or in this case a quick "thats not plugged in right". The experience and the overall professionalism has convinced me that when I do finally need that big repair job, I'll call these guys.

Booking an appointment was extremely easy, and we were able to get one just the next day. Communication was excellent with timely reminders and a call before our appointment. Kerry did a fantastic job both advising us and effectively resolving our issue.

I have all good things to say about 2 Sons Plumbing. My first experience was a few years ago and the whole process went very smoothly. Making the appointment was easy and quick, the repair was done with no problem and I thought the price was fair. Recently, Dave from 2 Sons came out to look at several plumbing problems I was having and, within a matter of minutes, all of the problems were diagnosed. Dave gave me options and estimates all before he left my house. I haven’t had the work done yet but appreciate the information and the prices seemed fair to me. Dave was on time, professional and very knowledgeable. 2 Sons are my go to Plumbers.

Bob at 2 Sons Plumbing was amazing! We had a horribly backed up kitchen sink drain and he was able to fix it, and save us some money in the process! He heard what we had to say about our issue and double checked everything. Super friendly and very helpful. Thank you for the amazing work Bob!

Stellar job by Carey and his team at 2sons today. I had a complex job -- installing a yard hydrant/faucet for a garden across the (private) street. They had to go into the floor of the garage, run piping under the floor, out of the house, across the road. Had to cut into the asphalt, trench down a couple feet, then patch it all up again, including fixing the garage concrete floor. Super job. Looks really clean. Got it all done in a day.

A wonderful experience every time with 2 Sons plumbing. Jake and Angelo helped us with our plumbing issue. They showed up on time and gave a very reasonable estimate for the repair. We ended up replacing a couple of toilets and a part of a sink drain. They came back the next day to complete the work due to our schedule. Excellent communication, prompt, and hard working! Thank you so much Jake and Angelo!! We are very happy with 2 Sons and have used them multiple times.
