All Seasons Storage - Lake Stevens 

We have used 5 Star Backflow Services for 3 years now. Each time has been efficient and thorough. They have very reasonable prices that don't get raised every year. They are always on time as well. Its been a pleasure doing business with them. We highly recommend them.

5 Star Backflow was excellent. Josh worked out an appointment time that fit my difficult schedule, arrived as promised, and was able to perform an unexpectedly needed repair to our backflow equipment. I'll be calling him again next year. Thanks, Josh!


Vivian S. - Seattle 

I messaged Josh today and was in need of backflow testing (an area which is desperate for attention). We no longer live in the home in Seattle so the appointment requires a bit of coordination with tenants. To my surprise, Josh jumped in and replied right away. He offered me some times and I was able to secure an appointment before my testing deadline. My tenant was able to connect to him with ease. Hey! I look forward to seeing the result and it's the first time I look forward to getting an invoice from someone. Thank you!


Taylor H. - Kent

Josh with 5 Star Backflow Services was very pleasant to work with. He gave me a date over the phone and I was out of town but he was able to complete the work without any inconvenience to me and (e)mailed the report to my utility company. Now I just have to write him a check. Price was very reasonable and I will continue to use him each year. Thanks again!


Brandon S. - Bellevue, WA

​Josh got back to me quick with an estimate and was able to get me scheduled 2 days out. He showed up on time, was very friendly and got the job done quick! He also got back to me later that day to confirm the paperwork had been submitted to the city. I will definitely use 5 Star again! Thanks!


Donna S. - Edmonds, WA

Josh was great! Very quick response time, great price. Will absolutely call him every year for backflow testing.


Giridhar K. - Bellevue, WA

Excellent communication, and smooth process.


Thu N. - Woodinville, WA

I left Josh a message on Yelp for a backflow test and he got back to me right away. He was willing to work out a schedule with me and got the job done so quickly. He also sent the report within 2 hours of leaving my house. Very efficient and professional. Couldn't be happier with his service and would give him more stars if I could!


Jin Y. - Kirkland, WA

Very fast and responsive service - my initial phone call was returned within 30 min. Josh was courteous and professional, and logistics/scheduling were handled very smoothly.


Anita T. - Seattle, WA

Left a message and they got back to us right away and quickly scheduled a testing. Very friendly and professional. He even put us in touch with a yard service to help repair our sprinkler system and will also help repair our outdoor lighting. Great fast service and they send in the report for you! Looking forward to continuing to work with them yearly.


Hwang T. - Mercer Island, WA

Never know the backflow got to be tested every year until I got a notice from the city. Contacted Josh on 23rd and on the 26th, just the day after Christmas, he got it done, and had the report sent back to the city right away. Very professional!! Definitely will recommend him to my friends.


Isaac C. - Bothell, WA

I rarely review any company unless I've received extraordinary service, which is the case with Josh and 5 Star Backflow. I used Josh to diagnose and repair a broken water line running to our house. Josh took great pride in his craft, showed up on time, worked hard and made sure the job was done right. I highly recommend 5 Star Backflow. Josh is a true example of professionalism and was really a pleasure to work with. Thanks for exceeding my expectations!


Quoc D. - Federal Way, WA

This business is very good in service. I contact them by YELP, and they answer me right away, they show up on time and know what they doing. The important thing is "the price is right." I will call them next time and the next time when I need their service. Thanks and keep up the good work.

Scott B. - Kirkland, WA

Josh VanQuaethem, of 5 Star Backflow, gets 5 stars from me. He persevered through some difficult backflow assembly installation conditions, including a very steep grade and poorly aligned pipes. Even though the installation was more complex and much longer than estimated, he did what I think is a superior job, and he stuck to his original quote. Thank you, Josh, put me on your calendar for regular testing in early May.


Aaron L. - Sammamish, WA

Never had to have my backflow tested before. Received my notice in the mail. Called Josh first and he was out within two days. Easy to work with. Would recommend to any friends or neighbors.


Amy W. - Seattle, WA  

First of all. I didn't even know what backflow testing was until I was notified that my business had to have it performed yearly. We had never had it done and I was worried we might have a problem. 5 Star was recommended to me by a friend who had used their services before. The owner responded to me very quickly and provided testing within days of being contacted. He educated me on what backflow testing was and why it is necessary. He assured me that things were in good shape at my business and agreed to return on a yearly basis. He was highly professional and his fee was very reasonable. I would definitely recommend this company to anyone in need of backflow testing in the Puget Sound area.
