Sump Pump Water Level Alarm

An innovative, Wi-Fi enabled high water level alarm for basement pumps, the AlertMaxx Two is designed to alert you if the water reaches a certain level within the sump chamber. The alarm is normally powered by 240V, but has battery backup in case of a power failure.

When used with a cavity drain system, the alarm carries out regular health checks on the pump system. It also provides an audible and visible warning if a pump fails. This ensures your basement remains protected from water ingress.

The AlertMaxx 2 alarm guarantees peace of mind by delivering real time updates on any potential issues before they happen. It achieves this by connecting a range of smart sensors through Wi-Fi to the PPS ‘PumpSecure’ system. You can also benefit from visibility over energy use. (Subscription required with PPS)

It also works as a highly effective standalone alarm in foul water situations.

When can the high water alarm be used?

Delta AlertMaxx 2 High Level Alarm is suitable for two applications:

Ground water – AlertMaxx 2 comes with a ‘broken finger’ float switch. This generates an alarm signal after pump one fails, leaving pump two (where fitted) to operate.  

Foul water – AlertMaxx 2 is supplied with a robust and reliable pendant type float switch to be fixed to pipework, pump or free hanging. It utilises a float weight (optional extra) to allow correct operation. 


This Delta water level alarm is easy to install requiring just two fixings and a connection to mains power and float switch.
