Kärcher SP 22.000 Dirt Level Sensor

Pumps away dirty water well.

A sturdy wastewater pump. Used here to empty a rainwater cistern. Due to the high head from the cistern, the pump initially needs some time to pump the water upwards. However, once properly activated, it operates very smoothly and with a high flow rate via the very handy discharge hose I also ordered. Since this pump isn't a flat suction pump, there was still some water (with sand) left in the cistern. I sucked this up with a Kärcher all-purpose vacuum (never crawl into a cistern unattended!!!), poured it into a garden bucket, and let the wastewater pump pump it upwards as well. To my delight, this worked without a hitch! Extremely happy with my purchase. This allowed me to completely clean and flush my rainwater cistern myself; if you hire a company to do this, you'll be paying through the nose. So, I've more than recouped the purchase price of the pump after just one use. I immediately threw away my cheap submersible pump, which made noise but didn't do anything.
