Our Mission

serving San Diego since 1991

Provide honest, reliable & guaranteed service to our customers. We make sure our customers understand the facts about home water treatment systems..


All Cities Water
has proudly been serving San Diego homeowners and Business customers since 1991.  Our staff and service technicians are highly trained and experts in their field.

We are one of the few licensed contractors in California, specifically licensed in Water Treatment, and we are also a licensed plumbing contractor.  #631304. (C55 & C 36)

What sets us apart from others?

We do not have a fancy sales office or showroom, just a simple warehouse/office in an industrial park.  No commissioned sales people, no high-pressure sales tactics and we do not use sub-contractors to install your system.
As licensed contractors we perform all installations, sales and service ourselves.  All this adds up to lower prices and reliable service.
