He was extremely nice and explained our options without trying to up sale. Pricing was fair and competitive with the other companies we had contacted. We decided to go with Water Purifaciions Systems due to their quick response, great communication, past reviews, workmanship, and their competitive pricing. On the day of install, Constantine and his team arrived when they said they would. Their work was efficient, clean, and custom. We did encounter one issue, but they rolled with it and resolved the issue with no problems. They cleaned up after themselves and went over the system in detail with us. They were patient and answered all our questions. I would definitely recommend Water Purification Systems for your water treatment needs here in San Diego County. Thank You Constantine and to your team.

Title: Still outstanding after all these years -- WPS delivers every time…read more I left a glowing review for Water Purification Systems over six years ago, and I'm happy to say they're still just as excellent today. Recently, I woke up in the middle of the night to find no water running in my house -- a total shock. (To be clear, this was not WPS's fault.) First thing in the morning, I called them in a panic. They answered promptly, walked me through how to get the water back on, and came out the very next day for maintenance. This review is for their continued care and stellar service over the years. I've had the pleasure of working with Eugene at WPS, and he is consistently professional, respectful, and incredibly competent. He explained that a power outage can disrupt the system's timing, and he patiently taught me how to adjust it so this doesn't happen again. Eugene is thorough, kind, and always delivers top-tier service. I just want to say again how much I recommend this company -- they truly go above and beyond.

After doing a lot of research on all the various water softener/conditioner options, I knew I…read morewanted to talk to people who specialize in water treatment as I was a bit overwhelmed with all the different information out there. I got in touch with Jaye at All Cities Water Treatment and he helped walk me through everything I needed to know about my water and how to treat it. He candidly answered some of the questions I had along with explaining the different options they offer but never tried to sell me on anything I didn't need. Jaye let me know that once I have a system it's very easy to add things on if I want. Jaye came out to my home for a consultation and to look at the plumbing. He drafted up a plan for the drainage of our new system and we got on the schedule for install the following week. The estimate was extremely fair compared to some others I had received. Eddie arrived promptly and did an amazing job with the install, replacing a failing valve, tucking and hiding piping for the drain. He was super knowledgeable on the system and walked me through the basics of what I needed to do. We are already starting to feel and see that the water is softer and cleaner. I will be recommending All Cities Water Treatment to anyone who is curious about water treatment!

The company, starting with Greg and Ben, then Brandon and Adam, were not just conscientious and…read morecourteous but extremely valuable in their consultative capacity. In contrast to others I have dealt with, they truly sought to inform me rather than trying to drive my decision or to "close a sale." I discussed frankly my "DIY" alternative and there was no pessimism or pressure, and I got the answers I needed to finalize my decision to replace, and the same with the more complex decision and tradeoffs of going tankless, and also they alerted me to the fact that I do not have a water pressure regulator, but, again, purely informatively, not in a "sales" mode, and referred me to resources to study further. I consider the price to have been competitive and also I have confidence in their guidance on the right model. They were punctual and once you know what you want, it is great to have it fully accomplished the next day. I recommend very highly the professionals who worked with me and the company they represent.

We've used Quick Water Heater & Filtration Company twice now and have been very happy both times…read more Our first install was back in 2019 with Gregg and Jacob, and everything went smoothly. This time around, our Rheem water heater failed before reaching even 7 years, despite having a 12‑year warranty. Even though Quick is closed on weekends, Brandon texted me and set us up first thing Monday morning. Ben (sales) was extremely helpful, walked me through all the options, and made a genuine effort to get Rheem to honor the warranty. Unfortunately, Rheem couldn't provide a replacement and instead offered fair market compensation (still TBD). Not thrilled with Rheem, but Ben handled the situation professionally and kept me informed throughout. We ultimately went with a Bradford White, and Sammy installed it the same day. His work was excellent--professional, efficient, and spotless cleanup. The Bradford White + installation was very reasonable and very surprisingly comparable to my prior installation. Very impressed with Quick's responsiveness, professionalism, and ability to turn everything around in a single day. Highly recommend them.

He was also very impressive when listening to him explain what our system could look like and what our options would be. At that time, we were already having an ADU built in our backyard, and when the contractor found out we wanted a new tankless heater and water filter installed on our main house, he offered us a discount and installed a tankless heater. It ended up being a big mistake as they did a very sloppy job. Fast forward to this past September 2025, and my wife put out a Yelp request to get a water filtration system installed. She did not know that Pure Plumbing had come out previously, but I recognized Bryan's name when my wife told me he would be coming to the house. He walked my wife through everything while I was at work, and she was impressed by him too. He even pointed out where our contractor's plumber had made a major mistake with our tankless heater. We ended up having Pure Plumbing install the water filtration system, the price was great, and they did a fabulous job. In addition, thanks to Bryan's alertness, we were able to have our contractor's plumber come out to fix their mistake. Thank you Bryan, and thank you Pure Plumbing. I highly recommend this company.
