12V RV Portable Macerator Waste Pump for Sewage, 12GPM Suction 3.2 feet Lift 10 feet, Complete RV Macerator Pump Kit for Right Out of Box

Didn't have to hookup and go to a dump statation.There was a clean out 2 sites over in the RV Park. All the Full hookup spots were taken. Was able to get one with Electric only.When the Package arrived went over to the Neighor and asked if I, could use the clean-out. Very Gracious Couple.It worked great and faster than any of us thought it would.They are going to purchase one in the very near future.

We are now full time RV, living on the back of our daughter’s property. We have power and water but no way to access the septic from where we are set up. This macerator works great for transferring from the black water tank into the tote tank that we put into the back of the gator (so the tote tank is actually higher than the outlet for the BW tank). Then we drive the gator up to the house and again use the macerator pump to transfer the waste into the septic system. Great cost effective solution.

Bought this to upgrade my RV water pump as the one stock was very noisy and very low pressure. This one works great. Remember you may need to change the fuse to for the higher voltage. I believe it takes a 20. My old one took a 15. I blew the 15.

I was sceptical of this pumps ability to handle our four 40+ gal waste tanks on our fifth wheel camper. I was pleasantly surprised when it pumped 140 gal of waste water without overheating and tripping the internal thermal switch. Also, much quieter than expected. I would agree that the cable connection for the battery is short. Was able to use a 20' camco sewer hose to reach the pump which needed to be towards the front of the campers battery compartment. I did have a problem with the switch spring failing after first use. However, it was easily fixed by unscrewing the switch and repositioning the spring.

I decided to bench-test it before installing it permanently. Coupe of buckets, some hoses and a pressure tank with a pressure gauge. It's REALLY nice and quiet, as long as there are no leaks in the suction. Mine had an air leak in the filter/strainer. I was able to stop the after a couple of tries. I do like how quiet it ran after that, so I hope I can make it work.The instructions are very poorly written. There is a pressure cutoff screw to adjust the pressure switch, and it seems to work ok... kind of (I was trying to set mine on 58 psi), and had some limited success, but the shutoff would only happen after a lot of pump chatter as the set point pressure was reached. The instructions seem to conflate this switch with the bypass screw (which must adjust a pop-off valve of some sort... no mention of how that is supposed to work, other than "The pressure gauge pointe jitter (sic) instantaneous data is shutoff-by-pass pressure". I've written and read a lot of technical stuff, but am not sure what that is supposed to mean.As to the bypass screw: Mine was threaded in at an angle (it's a stainless steel allen set screw about 3/4", takes a 5/16" allen wrench, not the 7/16 wrench the instructions describe), and did not seem to reliably adjust much of anything. Instructions say to remove it completely and screw it in 10 to 11.5 turns clockwise. The pump chatters as it reaches the setpoint pressure (58 psig in my case). What I wanted was the bypass to kick-in at about 65 psi (ie; never unless the cutoff pressure switch fails). Coudn't do it. I would presume this can be done by setting the pressure cutoff switch to a higher pressure than desired, adjusting the bypass to open at that pressure, then back off the pressure cutoff switch to the desired pressure. None of this is obvious from the instructions (they just say "unscrew it completely, then screw it in about 10 1/2 turns) Nothing about how it works. or how to set it dynamically.OK, maybe I am missing something, but since I am a pretty handy guy, I figured that with a little advice from Customer Service, I could make this work, maybe even fix whatever seems to be wrong with this pump. Called Customer Service at 11:00am this morning. Guess what I got? "Customer Service is not available at this time. Please leave a message at the tone". So I did. Never heard back. If I don't hear back before I get a replacement pump in two days, I am going to send this thing back. I will update later either way.Update two days later. Was never able to get in contact with customer service. I have a time constraint, so I did something I shouldn’t have had to do: I McGivered the bypass valve by removing its cover and shimming the screw to ensure that the bypass pressure would exceed the set point pressure. It worked. Pump ran smoothly and quietly during the bench test, so I went ahead and installed it.

I've only had occasion to use it one time, but it pumped out a full black water and grey water tank (over 100gal) with no issues. Allowed me to empty the motorhome tanks in my yard extending the use of my motorhome as a "guest house" to give visitors their own space without having to drive it out to a dump station during their stay.

Works great! Pumped my black tank 100’ to my clean out on house.

I only give 4 stars because it’s really inconvenient that it has the car battery hookups instead of a normal plug. Otherwise this product has been exactly what I needed. I use a 80ft garden hose and it works like a charm. Takes about 5 minutes to drain a 35-40 gallon tank. Also don’t let it run after it’s empty. It gets hot. Shut it off as quickly as possible after draining. Would recommend!
