Pool Leaking at the Equipment Pad in San Marcos, CA
A San Marcos pool showing water leaking at the equipment pad usually has a short list of likely causes. Drips and puddles at the pad trace to worn seals, cracked unions, or a leaking filter band rather than the pool shell. 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.
Likely causes in San Marcos
- A worn pump shaft seal or lid o-ring
- A cracked or loose PVC union at the pad
- A leaking filter clamp band or tank o-ring
- A failing multiport valve or diverter seal
- A corroded heater header or fitting
What to check before you call
- Trace the wet spot back to the exact fitting
- Check the pump lid, unions, and filter band for drips
- Note whether it leaks only when the pump runs
- Photograph the source before the service call
