Trusted South San Francisco Sewer Ejector Pump Repair & Installation

In South San Francisco, any bathroom, laundry, or fixture located below the main sewer line needs a sewer
ejector pump to move wastewater up to the building drain. Gravity alone won’t do the job — which is why sealed
basins, properly sized pumps, and venting are so important. Our licensed plumbers design systems that match
your fixture load, lift height, and pipe size, so the pump cycles efficiently without short‑cycling or
excessive noise. We also ensure gas‑tight lids, check valves to prevent backflow, and code‑compliant air
venting for safety. For ADUs and basement remodels in South San Francisco, our approach starts with an
on‑site assessment. We confirm clearances, electrical supply, and routing for discharge lines. Then we
recommend options — from rugged cast‑iron pumps to quieter, energy‑efficient models — and explain the
trade‑offs in head pressure, gallons‑per‑minute performance, and durability. If your existing basin is
undersized or not vented correctly, we can retrofit a new sealed basin with an external check valve and a
serviceable union for future maintenance. Every installation ends with a full system test: we run fixtures,
verify pump activation, check valve operation, and confirm air‑tight seals. Older homes in South San
Francisco sometimes inherit DIY ejector setups that mix storm water or lack backwater protection. Those
shortcuts create odors, premature pump failure, and even sewer backups. We correct these issues by separating
drains correctly, adding cleanouts, and using schedule‑rated discharge piping. Where appropriate, we’ll
perform a camera inspection of downstream lines to ensure there are no hidden restrictions that would overwork
your new pump. Documentation, permits, and inspection coordination are all part of our service. Reliability
matters. We stock service parts, offer 24/7 emergency support, and provide maintenance plans for South San
Francisco property managers and HOAs. Expect tidy work areas, careful concrete cutting (when needed), and
professional patching. We finish by reviewing operating tips — like what not to flush, how alarms work, and
when to call for service — so your system stays dependable for years.
