Water Filtration Systems
Orange County

Great experience working with Sergei and his helper on our new water softener installation. The entire process is smooth – quoting, scheduling, working, and Sergei has been very responsive and communicative. The quote is very competitive and the work quality is great, we got our water softener installed by the end of the construction day, in a good spot in our garage, with some new pipes connecting to the main water valve near the front entrance. Thank you so much. I’d work with Sergei again on future plumbing projects.

Sergei did a great job installing a water softener in our garage and a reverse osmosis system in our kitchen. I put the job out for bid on Yelp and every other water softener company replied by saying to call them. Sergei gave me a fair price right away and didn’t try to “up” it when he came out like one other guy did. He was always punctual and very neat. He had to cut a hole in the garage wall to get access to the pipes and he covered the hole where it looked nice and neat. He used copper pipes which to me said, “quality.” We had some errands to run so left him alone in our home as we could tell he was a person of integrity. Everything in our home was in perfect order when we got back after he had left. He is trust worthy. Give Sergei a call if you want pure water in your home.

I knew I had found a legit plumber when I spoke to owner Sergei on the phone and got honest, scientific answers to my questions about the best home water systems. Just check out ProFiltration website and you will see their comprehensive approach. Sergei and his assistant installed my Clack salt water softener and carbon filter using copper pipes. It took them less than 4 hours and they cleaned up every step of the way. They also avoided leaving me with open drywall cuts, unlike most plumbers. I’m also very confident that I got a great price on everything.

Sergei is an honest and competent contractor. He gave us a no nonsense quote that was highly competitive. Good communications throughout the whole process. I watched the entire install and it was done with professionalism and care. The water softener he installed is working well with zero problems. I rarely find a contractor these days who I can enthusiastically recommend to friends and family but Pro Filtration is easy to recommend for value, competence and communications.

Sergei and pro Filtration was great! Not only does he know about water treatment but he breaks it down so it’s easy to understand. Prompt, knowledge, transparent and great pricing makes it easy to recommend to my friend and family.

Sergei and his receptionist were very responsive. Sergei is highly trained and does not rush the job. I recommend this company!

Sergei was incredibly honest in giving us the best service possible in installing a new RO system at my tenant owned property. Extremely reasonable prices and excellent quality of work with installation. He also was very good with communication and showed up on time. I would definitely give him more business in the future and would recommend him for others looking for what he offers.

We used Sergei for our plumbing and water filtration services during a major renovation and couldn’t be happier with the products and services he provided. He is prompt, professional, and expedient with his work. I greatly trust his knowledge and expertise and would highly recommend him for any job, great or small!

Great service, starting from first communication till the very detailed instructions and tips on how to operate and maintain the installed system.

Sergei is definitely an expert and we would highly recommend him. Provided reasonable pricing, showed up on time, did a job quick and flawless.

We got the water softener and filtration and the difference in water quality is remarkable. The water tastes fresh and leaves no aftertaste. Bathrooms are free of pesky limescale which saves tons of time cleaning.

Sergey installed water softener and filtration system fast. As an extra he changed all house hose bibs. Everything is working just fine!

I purchased a reverse osmosis filtration system at Home Depot while it was on Labour Day sale. But installation was a bit complicated to DIY, so I decided to find the right person to do it for me. Out of all the offers received, profiltration provided the best price, and even more, he was available the same day. Arrived right on time, had every tool needed, and installed everything is just a couple of hours. No mess after; he even took the box and all the package. His experience and advice were highly appreciated. Will definitely work with him again when it is time to change the filters and make the maintenance of the system.
