One very important aspect of systems engineering is risk management.

When your are designing systems it is essential to assess what could go wrong and then identify what you can do to either eliminate or detect the problem before bad things happen.

Fluid systems are notorious for overflow issues, so establishing a constant passive monitoring system is needed.

Depending how critical the damage control needs to be, you can do anything from sounding an alert to automatic shutdown of the fluid transport.

In all cases, an emergency draining capacity is always recommended.

Just one of the many lessons learned in engineering.

Using a wireless link to shut off a pump that could flood your apartment makes me cringe. Perhaps you should install a float switch as a backup to physically cut power to the pump if the water level goes too high.
