Weak Pool Circulation in San Marcos, CA
Weak Pool Circulation is one of the more common calls we get from San Marcos homeowners. Weak return jets and poor turnover point to a clog, a dirty filter, an air leak, or a tiring pump rather than chemistry. San Marcos runs on Vallecitos Water District at 14-18 gpg, which is very hard water. Around here that means aggressive Colorado River water scale eating through equipment, plumbing, and pool finishes, and it shows up in problems exactly like this one. A specialist in the Refresh Pool Pros network can diagnose it on site in San Marcos and quote the fix in writing before any work starts.
