Customer Review: “It accomplished what I wanted it to do. I don’t moochdock but I do camp frequently at a rec area that does not have a dump station and nearest dump is 10 miles away, so I wanted to pump from the RV tanks to a portable tank pre-loaded into the back of a pick up so I didnt have to lift it (250lbs when full). I have used this pump twice and found that it actually worked pretty well. I did buy a female/female garden hose adapter so I can direct connect the hose to the portable tank inlet. Overall I am pleased with the purchase and would buy it again.”

Customer Reviews
Customer Review: “These RV toilets are very sophisticated which makes them complex. This part was exactly what I needed and the extra hose that comes with it is a bonus. Over time these hoses can have build-up which can break off when disturbed. This build-up is hard and can jam the system. Since you are taking the thing apart it is a good idea to replace the hoses. If you decide to keep existing hoses make sure you clean them throughly.”
Customer Review: “The pump is identical to the RV pump that I removed but the hose is a bit different. My guess is that it is the hose for the boat version of the Thetford Tecma toilet. I was able to use some of the new hose parts and some of the hose parts I removed and was able to fit everything together without any problems. I comment on this because you will need to save some of your existing parts until your install is done.That said, these are OEM parts and fit properly. The motor is quiet and does its job. Installation of the macerator pump was easier than I expected and everything was done and working in a few hours. My original pump lasted seven years before starting to fail. I used colored cable ties to mark each end of each wiring connector to make sure all were mated properly.”

Customer Reviews
Customer Review: “There were three reasons that I bought this pump: 1) Avoid the dump station at the campgrounds which I’ve waited in an hour long line before 2) Thoroughly clean the tanks at home where no one is waiting for me 3) Empty the tanks without moving the camper while camping. I’ve been able to use the pump successfully for #1 and #2 and I plan on getting a tank to achieve goal #3. Pros: – The pump is FAST. I can empty both my gray and black tanks totaling around 70 gallons in less than 5 minutes. – It pumps easily through a 50′ long 5/8″ hose up about 4 feet to a toilet just inside the house from my garage – It’s reasonably quiet while pumping and makes quite a bit more noise when the tank is empty making it easy to determine while it’s finished pumping – The flusher connection is very convenient for filling and flushing the tanks repeatedly. – The push button on/off switch seems to be very high quality. – The pump forms a very solid seal with the sewer hookup on the camper and doesn’t leak whatsoever. – It comes with an extra o-ring in case the one included on the pump wears out or is lost. Cons: – The wiring harness needs to be assembled and doesn’t come with any clamps or hook-ups.”
Customer Review: “The Flojet Macerator pump performs very well. The Flojet pump has lots of power. I have used it to pump the contents of a 41 gal blackwater tank thru 50 ft of 1/2 inch hose to my sister’s septic tank. I have also used it to empty a 46 gallon grey water tank. The grey water rinses the pump. This was on a shelf in my garage for 5 years before I used it. I used it a dozen times or more over the next few years when my motorhome was parked at my sister’s cabin. It then sat in a storage bay of my motorhome for 3 years. I then used it 7 times over a 30 day period in September 2025 to pump my RV’s sewage holding tanks while at my sister’s cabin, which shows it is durable. If you own an RV, buy this Flojet maceΕator pump”
Complete Buying Guide for Best RV Macerator Pump
Choosing the best RV macerator pump can feel like a big decision, but it’s all about making your RV experience cleaner and more convenient. Think of it as investing in your peace of mind on the road. Here’s a quick guide to help you find the perfect match for your travels.
Essential Factors We Consider
When picking an RV macerator pump, a few things are super important. First, consider the flow rate (measured in GPM β gallons per minute). A higher GPM means faster tank emptying, which is a blessing on a busy day. Most good pumps range from 9-15 GPM. Next, look at the grinding mechanism. Stainless steel grinders are generally more durable and effective at breaking down solids, preventing clogs. Don’t forget the power source; most RV pumps are 12V DC, drawing power from your RV’s battery. Some models offer quick-release fittings, which really streamline the setup and teardown process. Also, consider if it’s self-priming, as this feature makes starting the pump much easier without manual intervention. Think about where and how you’ll be using it. If you’re often setting up an outdoor living area, a good pop up canopy tent could be a great companion to keep you comfortable while you manage your tanks.
Budget Planning
You can find RV macerator pumps at various price points, usually ranging from $100 to $300 or more for higher-end models. While it’s tempting to go for the cheapest option, remember that durability and performance often correlate with price. A more expensive pump might offer a better grinding mechanism, higher flow rate, or more robust components that will last longer and prevent frustrating breakdowns. Factor in potential additional costs like extra hoses, adapters, or a storage case if they aren’t included. Investing a bit more upfront can save you headaches and expenses down the line. It’s similar to choosing other crucial gear, like a reliable portable jump starter for your vehicle β you want it to work when you need it most.
Final Thoughts
Ultimately, the best RV macerator pump for you will balance performance, durability, and your specific needs. Whether you prioritize speed, quiet operation, or a pump that integrates seamlessly with your existing toilet system, there’s an option out there. A good macerator pump makes managing waste on your travels far less daunting, letting you focus more on the adventure. After a long day of adventuring, ensuring a comfortable night’s sleep in your RV is just as important as managing waste.

Frequently Asked Questions
Q: What is an RV macerator pump and why do I need one?
A: An RV macerator pump is an electric device that grinds solid waste from your RV’s black water tank into a slurry, allowing it to be pumped through a smaller-diameter hose (like a garden hose) over longer distances or uphill. You might need one for more convenient and cleaner waste disposal, especially if you want to empty your tanks at home into a cleanout, or if dump stations are full or awkwardly located.
Q: Can I use a macerator pump for both black and gray water tanks?
A: Yes, most RV macerator pumps are designed to handle both black and gray water. It’s generally recommended to empty your black tank first, then use the gray water to help flush out the pump and hose afterward, ensuring a cleaner system for storage.
Q: How do I power an RV macerator pump?
A: Most RV macerator pumps operate on 12-volt DC power. This typically means you connect them directly to your RV’s 12V battery or a dedicated 12V power outlet. Some come with alligator clips for easy battery connection, while others might require a permanent wire-in installation.
Q: What kind of hose do I need with a macerator pump?
A: One of the biggest advantages of an RV macerator pump is that it allows you to use a standard 3/4-inch garden hose for discharge, rather than the bulky 3-inch RV sewer hose. This makes disposal cleaner and easier to manage. Just make sure the garden hose you use is dedicated for waste and not for fresh water!
Q: Are macerator pumps noisy?
A: The noise level varies between different RV macerator pump models. While they do produce some noise due to the motor and grinding action, many modern pumps are designed to be relatively quiet, especially compared to older models. Customer reviews often provide good insights into the actual operating noise.
