Kärcher SP 16.000 Dual

My previous submersible pump gave up the ghost (short circuit, but luckily no accident). This one has good suction and an automatic vent. However, I had to buy a separate check valve. You pay a lot of money for such a small thing, and it doesn't work perfectly, but it's better than no check valve, because then you'll immediately have 1-2 liters of water flowing back.

Simply does what it is supposed to do, makes little noise, without complicated accessories.

Used to pump out our crawl space after a leak. This couldn't be fixed until the crawl space was a bit drier... Worked very well! The cord was long enough, though I did need an extension cord for the back of the crawl space (house is 10 meters deep), but it worked perfectly. Even with dirty water. It's a shame you have to buy a hose for it, but I thought it was well worth the money.
