CSquared ProTip: Spring Jet Pump Priming #
Priming a jet pump is a critical rite of spring for cottage owners. Getting it right the first time prevents permanent damage to your pump’s seals caused by dry-run friction.
Preparation & Safety #
- Inspect the Foot Valve: Ensure your intake line’s foot valve is holding water. If it leaks, your prime will drop immediately.
- Power Off: Double-check that the pump breaker is OFF before starting.
- Check the Housing: Look for hairline cracks caused by winter freezing.
Step-by-Step Priming #
- Open the Priming Plug: Remove the hex-head bolt or plastic plug on the top of the pump housing.
- Fill the Housing and Intake: Slowly pour clean water into the priming hole. ProTip: Use a funnel to reduce air bubbles. Wait a few minutes for the “burp,” then top it off again.
- Seal the System: Once the water level is steady at the top, apply fresh Teflon tape to the plug threads and tighten. It must be airtight.
- The 45-Second Rule: Open a nearby faucet slightly and flip the breaker. If pressure doesn’t rise within 45 seconds, turn the power off and repeat the prime.
Troubleshooting #
| Symptom | Solution |
|---|---|
| No pressure rise | Re-prime and check intake connections. |
| Pressure drops after shutoff | Replace the foot valve. |
C2 Reminder: Ensure the system is thoroughly flushed of any winterizing antifreeze before use.
