Why Won't My Booster Pump Turn On?

Safety First

Before inspecting any electrical components on your water filtration system, always disconnect power to the unit. Booster pumps and their associated components operate on electricity, and working with live circuits can result in serious injury. If you're uncomfortable working with electrical systems, please contact our support team for guidance.

Check Your Power Supply

The most common reason a booster pump won't turn on is simply a lack of power. Start with these basic checks:

Verify the system is plugged in and the outlet has adequate power (test with another device)
Check your circuit breaker or fuse box for any tripped breakers
Inspect the power cord for visible damage, kinks, or fraying
If using a power strip or surge protector, try plugging directly into a wall outlet

Inspect the Transformer

Your booster pump uses a transformer to convert household voltage to the appropriate level. A failed transformer is a frequent culprit when the pump won't start.

Check that all connections between the transformer and pump are secure
Feel the transformer (with power on briefly), if it's excessively hot or completely cold, it may need replacement

Transformers can fail due to power surges, incompatible power supply, age, and improper wiring among other factors. If you suspect a transformer issue, contact us for a replacement.

Examine the Pressure Switch

The pressure switch tells your booster pump when to turn on and off based on water pressure in the system. If this switch malfunctions, the pump won't receive the signal to start.

Locate the pressure switch (typically a small box with wires attached, near the pump or on the filter housing)
Ensure the switch hasn't been accidentally bumped or repositioned
Check that wiring connections to the switch are tight and not corroded
Listen for a clicking sound when you open a faucet, this indicates the switch is activating

Verify Wiring Connections

Loose or corroded wiring connections can prevent your pump from receiving power, even when everything else is functioning correctly.

With power disconnected, inspect all visible wire connections for looseness
Look for signs of corrosion, discoloration, or burnt wires
Gently tug on connected wires to ensure they're secure
Check quick-connect fittings to make sure they're fully seated

Important: If you notice any burnt, melted, or significantly damaged wiring, do not attempt to repair it yourself. Contact our support team immediately.

When the Pump Itself Has Failed

If you've verified power is reaching the pump and all connections are secure, the pump motor itself may have failed. Signs of pump failure include:

A humming or buzzing sound without the pump actually running
Complete silence when the pump should be activating
The pump previously made unusual noises before stopping entirely
Visible leaking around the pump housing

Booster pumps typically last 3-5 years with normal use. If your pump is within this range and has stopped working, replacement may be necessary.
