Why Your Pool Pump Could Be Costing You $$$—Even When It’s Off

Your pool pump is one of the most essential—and expensive—pieces of equipment in your pool system. But did you know it could still be draining your wallet, even when it’s not running?

At Sparkling Pools Service & Repair, we often get calls from customers who are shocked by rising energy bills, thinking that simply cutting back on pump hours will solve the problem. The truth is, a faulty or outdated pump can cost you money in ways you may never have imagined.

1. Phantom Power Drain

Most pool pumps—especially older single-speed models—can still draw power even when they’re “off.” This is called phantom or standby power. If your pump isn’t fully disconnected or doesn’t have a modern energy-efficient motor, it may be quietly adding to your electric bill every month.

2. Leaky Seals and Valves

Even if your pump is off, a leaky seal or suction-side valve can allow air into your system, forcing the pump to work harder when it does run. This added stress shortens the pump’s life and increases your operating costs.

3. Backward Water Flow

When the pump isn’t running, improper check valve function can allow water to flow backward into the pool or spa, disrupting water chemistry and wasting treated, filtered water. This leads to more frequent chemical rebalancing and longer filtration times when you do turn it back on.

4. Clogged Impellers or Debris Buildup

If your pump isn’t regularly cleaned, debris like leaves, sand, or even insects can block the impeller. This reduces efficiency and increases the energy needed to circulate water—leading to higher bills even with fewer pump hours.

5. It’s Just Old

If your pump is more than 8–10 years old and hasn’t been upgraded to a variable-speed or energy-efficient model, it may be operating with outdated tech that isn’t optimized for South Florida’s pool demands. You might think you’re saving money by keeping the old pump, but you could be losing much more in wasted electricity and repairs.

How to Tell If Your Pump Is the Problem

• Your electric bill is unusually high—even in the off-season.
• You hear strange noises like grinding, squealing, or rattling when the pump is on.
• The pump doesn’t hold prime well or takes a long time to start.
• You notice changes in water clarity, pressure, or flow rate.
