Water Filtration Services

Why Do it?


San Diego’s hard water is very hard, and can destroy your pipes, fixtures and water heaters. Adding a water filtration system can give you cleaner, silkier water, and save you from future repair costs.

We repair nearly any type of system, quickly and affordably. From reverse osmosis to salt systems to whole house carbon filtration, we can help fix your water system.



We conduct thorough inspections to ensure your system is running smoothly and efficiently. Schedule service at least every six to 12 months. Give us a call. We can help.

Not all homes are created equal, so we build and install custom water filtration solutions to fit your needs. Call for a free consultation. We are here to help.

Our goal is to deliver the highest quality service and ensure your 100% satisfaction. In fact, we guarantee it.

I was so impressed with Jacob from start to finish. He responded quickly to my request for a quote and provided me a price over Yelp messaging (that was accurate when he did the work). And he was so communicative throughout the whole process. Thank you, Jacob!
