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.

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.

Really dislike giving low star reviews. This is an established company. We enjoyed working with…read morethem in the past. Higher in pricing, but we used to praise their customer service. We are loyal to our vendors/contractors as great workmanship is not always easy to come by. In the past Jacob, Erik, and others on the team were always professional, prompt, down to earth-- and all experts. They installed our 3 water heaters from them and a whole house filtration system. We have recommended them to our neighbors as well. Had the most uncomfortable conversation with owner Brandon who we've never interacted with in the past. Shockingly rude. I even said, "sounds like I caught you at a bad time" - yikes. A top contender for most negative and weird vibes from a sales/client interaction. This call happened after a slightly frustrating visit with Ben who admitted he only has 1 year of experience and was trying to keep up as best as he could. He was actively trying to learn on the spot. He was honest which I commend. Ben left saying he needs an actual technician present along with the owner's help to develop a more solid option and plan to move forward. Not a problem at all. It must be frustrating being an expert in your field having to speak about the same products and concepts with home owners who are relearning different/new systems on the fly. But if customer service is not your forte, stick to delegating and take hospitality courses so your loyal customers don't feel like they have to be apologetic for having questions on a $11k quote. Sadly, a "could have been better" 2/5 star experience, wish we could stick with them. Pro tip, maybe ask to exclusively interface with the seasoned members of their crew with 5+ years of experience so you avoid any negativity and can actually get the work you need done.

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!

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.
