    What the Pros Say

    "Don't overcomplicate it. A simple, hardwired float alarm just works. It's the first line of defense, and in my experience, the fancy smart alarms just introduce more points of failure. I want to hear a loud buzzer, not get a text message when sewage is an inch from my customer's basement."

    "An alarm is mandatory for any system with a pump, period. It turns a potential $10,000 disaster into a manageable service call. We explain to homeowners that the cost of the alarm is the cheapest insurance policy they can buy for their septic system."

    "The key is setting the float correctly. You need to position it to give the homeowner enough time to call us before the water level reaches the inlet pipe or backs up the pump. Setting it too low causes nuisance alarms; too high, and it's too late."

    "From a business perspective, installing a quality, weatherproof alarm on every pumped system reduces our liability and emergency callbacks. It protects the customer's property and our reputation. We bundle it into our new system installations because it's non-negotiable for system health."
