When to replace your pool pump — five signs to act

Pool pumps almost never fail catastrophically. They warn you. The homeowners who get caught flat-footed in the middle of summer are the ones who missed three months of small signals. Here is what to watch for.

1. Louder than it used to be

A new pump runs around 65 dB. If yours is now closer to a dishwasher in distress, the motor bearings are giving up. You probably have six to twelve months of runtime left.

2. Tripping the breaker

If the pump trips the breaker on startup or mid-cycle, the motor is drawing too much amperage. Could be a capacitor (cheap fix) or a winding short (replace the pump).

3. Losing prime more often

Suction-side leaks make a pump lose prime. So does a worn impeller. So does a cracked pump basket lid. If you find yourself opening the pump lid to refill it more than once a week, get it diagnosed.

4. Energy bill creep

Single-speed pumps are now banned in California for residential pools larger than a hot tub. If you are still running one, your replacement quote is a variable-speed pump that uses a quarter of the energy and lasts longer. Either you replace it on your terms or the next inspection forces you to.

5. Visible rust or moisture at the seal

Wet streaks below the pump, rust on the bolts that hold the motor to the wet end, or condensation on the motor housing — all signs the shaft seal is failing. The seal itself is a cheap part, but once it leaks, water gets into the motor and you are looking at a full replacement within weeks.

What we install most often

Pentair IntelliFlo3 VSF for most valley pools, Jandy ePump VS for Jandy automation pads. Both pull around 1.8–2.0 amps at low speed. Standard install is half a day for a like-for-like swap, full day if we are also rebuilding the suction-side plumbing. Variable-speed quotes typically include the LADWP rebate paperwork so you get the rebate credited in week six instead of chasing it yourself.
