Mercer Island Water Softener

Do you have hard water in your Mercer Island, WA area property? Have you decided to have a water softener system installed and are looking around for experienced professionals to do the job? Let 2 Sons Plumbing take care of your water treatment and conditioning needs.

Though hard water may not be a significant safety hazard, the harmful minerals present in it do cause a few problems. Installation of a water softener system is the ideal solution to combat these issues.

Property owners who hire us to install a water softener system in their Mercer Island property and to route the main water supply through it can expect a few benefits from the project. These include:

Longer-lasting plumbing appliances
Reduced usage of water, soap, and detergent
Brighter, softer clothes after laundering
Easier cleaning of floors, bathtubs, glasses, dishes

Mercer Island Hard Water

What makes dealing with hard water quite challenging is that it is a pervasive problem. It is not only a faucet or two in your property that will have water with excessive amounts of magnesium and calcium. You will have hard water throughout your Mercer Island property, exposing all your plumbing fixtures and pipes to it.

That is why we recommend a comprehensive water conditioning solution. Make hard water problems a thing of the past by scheduling a visit by our plumbers for installing a whole-house water softening device.

We are committed to helping you make a worthwhile investment, and our technicians go all out to ensure that the system installed in your property:

Is correctly-sized
Carries a respected brand name
Has been built for excellent performance and durable use

Mercer Island Water Softener System

The efficiency and longevity of your water softener system depend upon how well it is installed. Even premium-quality products can fail if inexperienced technicians do their installation and servicing.

Make your water conditioning device work optimally by getting it installed by us. We put well-trained, seasoned plumbers on the job to ensure a high-performing water softener system in your Mercer Island home or business place.

Your 100% satisfaction is our top priority. So, we provide you with sufficient respite from hard water:

With a smooth, well-organized process
At the most competitive prices
In a friendly, stress-free manner

Call 2 Sons Plumbing at (206) 487-1757 to know more about the advantages of investing in a water softener system for your Mercer Island property.

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.

Brandon and Ethan were awesome. I had a basic plumbing issue that I was too scared to address myself. They were very non judgmental and provided excellent customer service. I totally recommend 2 Sons Plumbing.

Woke up this morning to find a leak under kitchen sink !
Wasn’t sure who to contact. Did some research and came up with 2 Sons Plumbing.
Contacted them and set up time for today.
Kept us informed about time and who would be doing the job.
Angelo and a trainee arrived on time.
Assessed the problem and gave us a quote. Did the job in timely manner.
Finished and cleaned up area.
They charged the exact price they quoted. Gave us a one year guarantee.
