Puragain Water's customer service and installation were absolutely amazing! The quality of the water in the entire household is also incredible. The attention to detail throughout the process by Chris, the sales water specialist, and David, the installer, was phenomenal. I would highly recommend Puragain Water if you live in Southern California. Definitely opt for the alkaline water filter as well as it produces amazing drinking water. One of the best home services I have ever experienced!

Just had our consultation with Michael M. and I'm so pleased with his level of service. He was so polite, and very pleasant. He explained everything thoroughly and asked if we had any questions. He showed us online what the system looks like as well as where the spigot would go. He walked through the financing and also the process during installation. I'm looking forward to experiencing the system and will update my review accordingly

I just purchased the water system for my kitchen. The water is great and much cheaper than buying cases of water. The service was top notch from start to finish, the sales associate was very professional and the plumber was also very professional and kind, there was no mess and service was fast. I'm very pleased with the water it taste great, I'm mad at myself for not doing it sooner. Very happy with Puragain Water, I'm recommending this to everyone that wants to save money, time and our landfill.

Awesome services and great system set-up. Michael and Larry were on time and got the job done in a timely matter. The install on the system was clean and secured properly. Once the job was done they cleaned up and took all the empty boxes. If you want someone to come out ask for Michael. He was very detailed with what you were getting and showed the difference between your current water and their water system. Michael also followed up to make sure all my questions and concerns were answered.

Pretty damn phenomenal. I had been debating and researching water softeners and filtration for quite sometime now when I just happen to come accross a Facebook ad for Pureagain water and their filtersorb unit. I inquired and made an appt. I liked what I heard from Lonnie when he met with me at home. I decided to go through with it although my work schedule got in the way a bit. Lonnie was able to get his installer out the very next day to do a great job installing our filtration unit. We couldn't be happier. Thanks again.

Love Love my whole house filtered water plus I had the alkaline installed as well. Big difference on water change. No more hard water on my shower doors, in my dishwasher, or anywhere else. The water taste so clean and fresh when drinking it. It was the best investment I have made and I wish I would of done it a long time ago. I save money and the earth by not buying water bottles anymore. The works were very informative and super nice. Thank you again!

Lonnie and 100% family owned team are ROCKSTAR's and have ABOVE & BEYOND Service! They will come out and test your chlorine, calcium and ppm in current tap water for free, and show you how to get your tap water ppm from the really bad SD tap of 362ppm+ all the way down to only 10-20ppm! This is a MUST if you want to protect you and your children's longterm health living in the drought-ridden, sewer-to-tap SD water. Thank you Lonnie for your family's continued commitment to protecting us locals!

Frequently Asked Questions

Hard water is caused by dissolved minerals such as calcium and magnesium. Although these minerals are not harmful, and can actually be beneficial, when in high concentrations they can cause your water to become hard. Hard water can dry out your skin, cause scale buildup in your pipes, and leave a layer of residue on surfaces that it comes in contact with. The best way to remove hardness from your water is by installing a whole house water softener.

Although San Diego water is technically within the threshold of acceptable contaminant levels, this does not necessarily mean that there is no risk in drinking it. Many of the contaminants found in San Diego water, although within the guidelines approved by the EPA, long term exposure to these contaminants can potentially cause long term health issues including cancer and other diseases. It is always best to make sure that your water is treated at the point of use with a whole house water filtration system, water softener or reverse osmosis system.

Scale in your pipes and fixtures is caused by the buildup of hard minerals like calcium and magnesium. A NAC (Nucleation Assisted Crystallization) whole house water softener can neutralize these mineral ions which will in turn prevent and remove scale hout your home. There are many types of water softeners available, however we highly recommend a salt free water softener.

Traditionally, people have used salt based water softeners to remove calcium and other hard minerals from their water supply. Today, with the advancement of water softening technology, we offer a salt-free water softener that uses nanotechnology to neutralize the calcium ions, rather than removing them. This allows the calcium and other minerals to remain in the water, while at the same time preventing them from sticking to the surfaces of your pipes, appliances and fixtures, ultimately improving the life of your home’s water systems.

A salt based water softener uses sodium to remove calcium and magnesium from your water. Although this method will give your water a softer texture, there are some downsides to this method. Salt systems require a lot of maintenance, they are bulky, and they waste thousands of gallons of water a year. A Salt-less (NAC Water Softener) uses nanotechnology in order to neutralize the calcium and magnesium molecules rather than removing them These systems require no tank, use no electricity, and waste no water, which is especially important here in San diego where we are typically in a draught.

If you sell your house or plan on moving, don’t worry. Provided you’re moving within our service area (San Diego, Riverside, or Orange county), we’ll move your system one time free of charge.
