Ama-Drainer 301C Pump: A Surprisingly Simple Fix My Ama-Drainer 301C pump is installed in a KSB Box Mini—probably the kit your plumber installs for washing machines or small sinks that sit below the household waste line. Normally, you’d think this thing has an easy life… until it doesn’t. After my sump overflowed three times, I had cleaned the pump it worked after a good clean everytime, I finally called the plumber in the hope to use my building warranty to have it replaced.

Hacking the Pentair Jung Pumpen AGR device My house came with a strange little device called a Pentair Jung Pumpen AGR. Honestly, it might be the most overpriced gadget I’ve ever seen — essentially a passthrough plug with a small leak sensor that triggers a loud alarm. There’s no configuration, no smart features, and it’s only IP20 rated. Yet somehow, this thing sells for over €300(!). I’d never paid much attention to it — until recently, when a small leak (thankfully no real damage) set it off.
