RV Waste Pump, 12V Self Priming Macerator Pump, Portable Quick Release Waste Chopper Pump for RV Camper Trailer Boat, 30s Run Dry Protection

Worked perfectly out of the box, chopping speed was a little slower than I expected but that was probably due to using a 20 foot extension cable to plug into the car's lighter port. Emptied my 40 gallon black and grey tanks in about 15 minutes!EDIT: Has been running smoothly almost 3 months now. Also, chopping speed is much faster with the car running vs just using the battery. Gets the job done right!

It does what it’s meant to do,will not chop up cloth rags,so beware of what’s in tank,we had a used RV and previous owner just threw whatever in the toilet,as for the pump it works strong ,no issues at moment

I have been using this for a couple of years now and it has been working well. I am able to pump into my portable waste water tank in the back of my pickup which make it easy to transport to the dumping station.

This thing works great. Seems good quality, easy to hook up. I shortened the clear discharge tube so there would be no chance of blowing it. Used a 14 Guage extension cord 16 ft long, and modified the ends to accept the power switch and pump adapter to reach the batteries at the front of my trailer. Have pumped through 100 ft of 5/8 garden hose twice, no problem. Pumped 40 gal black tank then 60 gal grey in about 15 min. Would be faster if you used 3/4 in hose.

I was a little skeptical, but this thing does exactly what it's supposed to do. I have my trailer parked in my driveway and a cleanout about 10 feet away. I've used it twice and so far it's done exactly what it was supposed to do. Time will tell, but as of now I'm a happy camper. One thing to note, the 12V plug is a little short. I had to buy an extender to run it inside the trailer.
