The flow figures are listing values, not a runtime estimate. The product listing does not give a universal pit diameter or battery runtime, so check the pump and battery instructions for your installation.
No-buy
When should you skip adding another device?
Keep the pump or alert setup if it matches the pit, battery, and response plan. Decide where water could reach a sensor before choosing a rope or puck. A sensor detects water; it does not pump it.
Setup checks
What should you check for pit fit, power, and alerts?
- Confirm pump fit.Use the ESP15 instructions to check pit fit, discharge route, float clearance, and installation details. The listing requires a separate 12V battery.
- Choose the sensor path.Use the YoLink rope sensor when its 4.2-foot cable can cover the intended path. Choose the puck kit for separate points; its package includes a hub and four sensors.
- Match battery and charger.If you add a charger, check it against the selected battery instructions. The NOCO listing supports 6V and 12V battery types; it is not included with the pump.
- Test each function separately.Follow the manuals for pump operation, the sensor alarm, and any remote alert path you plan to use.
