Six Signs to Watch For

When Your Pump Is About to Quit on You.

Pumps almost always give warning before they die — you just have to know what to listen for. If you’re seeing or hearing any of these, schedule a check before the failure becomes a flood.

Strange Noises — Grinding, Rattling, Humming

A healthy pump is quiet. Grinding usually means the impeller is hitting debris or the bearings are failing. Rattling means parts are loose. Humming with no flow means the motor is seizing.

Pump Runs Constantly

If your sump or well pump never shuts off, it’s either undersized, the float switch is stuck, or there’s a leak somewhere downstream. Either way, it’s burning out the motor by the hour.

Pump Won’t Turn On at All

Could be electrical (breaker, capacitor, switch). Could be mechanical (seized motor, broken float). Either way, you have minutes before the basement starts collecting water or the well runs dry.

Water in the Basement or Crawl Space

Pooling water means your sump pump isn’t keeping up — or has stopped entirely. Even small puddles will turn into mold, rotting framing, and ruined storage if you wait.

Low Water Pressure or Sputtering Faucets

For well pump users, weak flow or air sputtering from the tap is the classic sign of a failing pump or pressure tank. Catch it now or risk waking up with no water at all.

Frequent On/Off Cycling

Short-cycling burns out motors fast. If your pump kicks on every minute or two without obvious cause, the pressure tank, switch, or controller needs attention — not the pump itself.

Catching pump issues early saves the flood. If something feels off, call us today.

Why Pumps Work Harder Here

North Bay Homes Need Reliable Pumps.

Three things make pump failure especially common — and especially expensive — for Sonoma and Marin homeowners.

Wet Winters & Atmospheric Rivers

North Bay winters bring weeks of heavy rain — the kind that pushes sump pumps to their limit. Older or undersized pumps fail right when you need them most: at 2 AM, during the worst storm of the year.

Private Well Dependence

Many properties in West Marin, Penngrove, Glen Ellen, and rural Sonoma County run on private wells. When the well pump fails, you don’t just lose water pressure — you lose water. Period.

Aging Crawl Space Drainage

Older North Bay homes weren’t built with modern foundation drainage. Many rely on a single sump pump as the only line of defense between the soil and the floor joists — and most are 10–20 years overdue for replacement.

Our Pump Services

Every Pump in Your Home, Done Right.

From the sump in the crawl space to the well in the back forty — if it pumps water, we install, repair, and replace it.

Sump Pump Service

Installation, repair, and replacement of sump pumps that protect your basement and crawl space. We size them right for your home and your local rainfall — not the manufacturer’s generic chart.

Well Pump Service

Installation and repair for submersible and jet pumps. Pressure tank diagnostics. Dry-well troubleshooting. We work on private well systems across West Marin, Petaluma countryside, and rural Sonoma.

Sewage Ejector Pumps

For basement bathrooms, laundry rooms, and any fixture below the main sewer line. We install and service ejector pumps that move waste up — reliably and odor-free.

Battery Backup Sump Pumps

The biggest sump-pump risk in the North Bay isn’t the pump — it’s losing power during a storm. A battery backup keeps your basement dry through PG&E PSPS shutoffs and storm outages.

Pump Maintenance & Inspection

Annual checkups that test the float, clean the basin, verify the discharge line, and confirm the backup is ready. Cheap insurance against a $5,000 flood claim.

24/7 Emergency Pump Service

When the pump dies during a storm, you don’t have hours to wait. We dispatch around the clock for sump and well pump emergencies — with common pumps stocked on the truck.

The West Coast Difference

Pump Specialists, Not Generalists.

Pumps aren’t side work for us. We size them, install them, repair them, and stand behind them — because losing your sump or well pump isn’t the time to find out your plumber doesn’t really know pumps.

Why Homeowners Choose Us
  • Common Pumps Stocked on the Truck

    When your pump fails, we don’t leave to go get one. Standard sump and well pumps are on the truck — same-day replacement is the rule, not the exception.

  • Properly Sized for Your Home

    We don’t default to the cheapest pump on the shelf. We size based on your home’s size, drainage area, and local rainfall — so the pump actually keeps up.

  • Battery Backup Expertise

    PG&E PSPS shutoffs and storm outages are exactly when sump pumps need to run. We install and service the battery backup systems that make sure they do.

  • Warranty on Every Install

    If we installed it and it fails because of how we installed it, we come back and make it right. The pump warranty is the manufacturer’s. The install warranty is ours.

Common Questions

Honest Answers About Pump Service.

How often should I replace my sump pump?

Most residential sump pumps last 7–10 years. If yours is over 10, it’s on borrowed time. We recommend replacement before failure rather than after — the cost of a new pump is a fraction of the cost of cleaning up a flooded basement, and your insurance deductible probably exceeds the replacement.

What’s the difference between a sump pump and a sewage ejector pump?

A sump pump moves clean groundwater out of your basement or crawl space. A sewage ejector pump moves wastewater up from a basement bathroom or laundry to reach the main sewer line. Different pumps, different applications, different builds — they’re not interchangeable.

Do I need a battery backup for my sump pump?

If you’re in the North Bay and your basement matters, yes. Storm-related power outages and PG&E PSPS shutoffs happen exactly when your sump pump needs to run hardest. Battery backups typically run $400–$900 installed, and pay for themselves the first time the power goes out during a storm.

How much does sump pump replacement cost?

Most standard sump pump replacements run $500–$1,200, including the pump, install, and old-pump removal. Higher-capacity or specialty pumps run more. Battery backups add $400–$900. We give upfront quotes — not vague ranges that change at the end of the job.

My well pump won’t start — is it the pump or the pressure tank?

It’s often the pressure switch or tank, not the pump itself — which is good news, because those repairs are far cheaper. We diagnose the whole system before recommending a replacement. Plenty of homeowners get talked into a $3,000 pump when a $200 pressure switch was the actual problem.

Can you service my pump on a holiday or weekend?

Yes. Pump emergencies don’t schedule themselves around business hours. We dispatch 24/7 for sump and well pump failures — storms, power outages, dry wells, the works. After-hours rates apply, but no “emergency surcharge” gimmicks. The price you’re quoted is the price you pay.

Pump Acting Up?
Don’t Wait.

The water won’t. Whether it’s a basement flooding tonight or a sump pump that should have been replaced last spring — let’s get a real plumber out today.
