Recommended Customer Reviews

Hello fellow yelpers,
I've had David and his crew set up the water filtration system for reverse osmosis drinking water and soft shower water for my house when I became a proud San Diego home owner in 2017. But it wasn't until today I realized just how above and beyond this company goes. They have state of the art equipment and technology to monitor even the tiniest of leaks. Which is what I had last night, but a big leak under the kitchen sink.
David showed up today, within half day business time. And guess what? The leak had nothing to do with his water filtration. He helped me solve a problem that could've become a much much bigger problem.
I see them once a year for maintenance. They are reasonable in costs.
I just wanted to say I never get paid for my reviews. It's hard to impress me and I have high standards. David and his company are ethical, hard working, and consistent. And they impressed me.
Many thanks to David and all my fans!
Much love,
Esther

From start to finish -- was exactly what we had hoped for in having a drinking water reverse osmosis system installed in our home. David was very responsive, professional, and friendly in all communication and follow-up. He was patient in answering our questions, as this was new for us and we needed an education to make the best choice. Scheduling was easy and convenient. Eugene, the installer, arrived on-time. He was professional, friendly, and very thorough. The best part is that my husband *loves* the taste of the water -- even without the alkaline filter! I was worried about that, as we have been lugging 5-gallon bottles of water purchased from the water store for years and years -- finally Hubby does not have to do this inconvenient, time-consuming, expensive, and physically taxing chore any more -- free at last, with our new reverse osmosis system from WPS. Life-changing! Thank you.

Installation was done on time and very professionally. I found a minor issue shortly after the install team had left and called, leaving a voice-mail. Since I was their last job of the day I expected them to come back the next day, but I got a call back with in 15 minutes and the guys were back shortly thereafter and resolved the issue. Really customer oriented, conscientious team, that got the job done.

Very good workmanship and professional company. Thanks for the new system! The new faucet and system looks great in my new kitchen. Thx for checking and adjusting my water pressure as well!!!!!!

Very courteous and professional with extremely reasonable pricing. Constantin answered all my questions I had prior to installation and came up with an optimal solution of whole house water purification for us. I had a quote elsewhere, but their quote was far more expensive than WPS, and the system suggested by them (this business is a top-rated one on Yelp) was an older model than the one installed by WPS. The overall experience: easy quote and scheduling, showed up on time, professional installation, and a great water purification as the result.

Installed water softener. Great service and very friendly. Lowest price in San Diego, with actual good equipment.

Eddie at WPS was on time, made installation easy & was very friendly and informative with no pressure. We wanted to rent a reverse osmosis water filter system for our kitchen sink. They had the best price, a great contract and since it included maintenance & installation: it was a no-brainer. It was all taken care of within a few hours... We'll never use Culligan again! We're understanding now why they get such great reviews and we're very happy now with our delicious, ultra-pure drinking water!

Constantine provided us the best service installing our reverse osmosis system this week! He was extremely knowledgeable and went above and beyond to provide us with the most superior service we could ask for. We could not be more satisfied! Thank you!!!

If you are looking for a reasonably-priced and very high-quality reverse osmosis system to rent or buy, Eugene at WPS is the man to speak with. I am renting a 3-gallon, under-the-sink R/O unit from him, primarily because it comes with free installation and free annual maintenance.
Girls hate maintenance!!!
My unit makes the best tasting water, and a lot of it, very quickly!! Constantine was my installation technician. He took his time, was meticulous about the installation, and gave me all the instructions I needed just in case (which has never happened to me once in many years of renting a system).
Water Purification Systems is top-notch! They are fair, and they care! I can recommend Eugene and WPS HIGHLY to any family or company, big or small!! I am really happy!

WPS was responsive, professional and they did great work. I highly recommend using them for any water purification system you are thinking of putting in your home or business. Amazing service!
