Services
Water Filtration
Our water filtration services provide clean, safe drinking water for residential and commercial properties. Using advanced reverse osmosis and whole-house systems, we remove contaminants like chlorine, sediment, and heavy metals. Clients benefit from improved water taste, reduced health risks, and protection for plumbing appliances.
Plumbing Repair
We offer comprehensive plumbing repair and installation, including leak detection, pipe relocation, and fixture replacements. Our licensed technicians address issues like dripping faucets, running toilets, and water heater malfunctions. Services ensure efficient plumbing systems, preventing costly water damage and reducing utility bills.
Water Softeners
Our water softening systems combat hard water by removing calcium and magnesium minerals. This prevents scale buildup in pipes and appliances, extends equipment lifespan, and improves soap efficiency. We install salt-based and salt-free systems tailored to household or commercial needs.
Reverse Osmosis Systems
Reverse osmosis systems deliver high-purity drinking water by filtering out impurities through a semi-permeable membrane. Ideal for kitchens and offices, these systems provide great-tasting water for drinking, cooking, and ice-making. We offer under-sink and commercial-grade installations with leak detectors for safety.
Leak Detection
Our leak detection services identify and fix hidden water leaks using advanced tools. Timely repairs prevent structural damage, mold growth, and inflated water bills. We service residential and commercial properties, ensuring minimal disruption during repairs.

Team at Water Purification Systems Inc. exceeded all my expectations! I was referred to them by my friend. During COVID pandemic I realized that it was difficult for me to constantly buy bottled water and carry it upstairs in a high rise building. In addition to that, there was too much waste. I called WPS to get more information regarding water filtration systems. Their representative explained everything thoroughly and offered an estimate. The price was reasonable and competitive. And I was able to schedule an appointment in a few days! Wow!
WPS representatives showed up on time, fully equipped

Water Purification System was recommended by a friend of mine. So I have contacted them and arranged an appointment for the next day. Their representative showed up on time was very professional and answered all my questions. I decided to install a Water Softener and a under-sink drinking system (reverse osmosis) with an alkaline filter. I am extremely happy with the systems I have got from them. My water now feels soft and clean and I do not see any build up on my fixtures anymore. My alkaline water taste way better than any bottle water I have tried before. I had a great overall experience

Without a doubt Water Purification Systems has the most professional and knowledgeable team from this industry. Prompt reply; Quick on-site visit schedule; Punctual; Very Knowledgeable and friendly; ; Competitive prices; Professional installation and the most important extremely satisfied with the product itself. So I got a whole house system installed (water softener +water filtration) and also a reverse osmosis with alkaline filter under my kitchen sink. The alkaline water does taste amazingly and most important no more bottle waste! Also the water in my entire house does taste and feel great

I have never had any issues with the hard water before I moved to San Diego. After a while living here I noticed the huge amount of scale building on my dishwasher, laundry did not feel the same, and my skin felt dry every time I showered. I did some research and found out that the hardness in southern California was extremely high. I did reach out to couple Water Filtration Companies to get some more information on solutions to fix my problem. Do not get into easy solutions such as, whole house systems with no waste or no salt required as they dont work at all. As my friend installed one of those

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

I noticed our fixtures and shower tubs kept the building the incredible amount of scale. We did a whole house renovation and paid a lot for the new fixtures. As I started to research the local water problems in San Diego I realized the extreme level of hardness in our water due to natural environment. Also I am very careful in picking the right solution and the right company. Just beware as some companies offering one system fix all problems type of solution. To eliminate the hardness from the water only salt based softener is efficient anything else can not even be called a softener by its nature
