Best RV Macerator Pump: Make Disposal Easier

What Is a Macerating Pump & How Does It Work?
To be blunt, an RV waste macerator pump grinds up solid sewage. These impressive aftermarket devices enable RVers to discharge solid effluent through regular garden pipes. This macerated sewage can travel faster and more efficiently than solids. They are also useful at eliminating clogs and other messy drainage issues.
Unlike firm sewage, the macerated slurry is less impeded by gravitational forces and density differences than regular human waste. As such, a good product also helps to eliminate otherwise prohibitive hazards, such as hilly landscaping and awkwardly positioned dump stations. Since these pumps grind sewage so well, they also enable travelers to dump their RV sewage into a private septic system such as in sewers and toilets.
What are the Benefits of Owning a Waste Pump for RVs
For many travelers, an aftermarket sewage elimination system is integral to an enjoyable experience on the road. An untimely solid waste issue can put a significant dampener on your road trip. Typically, a macerator waste pump is easy to install and operate with most connecting directly to a generator or your RVs battery. They also use a nominal amount of energy to slice and dice through thick effluent products.
In doing so, they enable RVers to overcome otherwise prohibitive obstacles, such as gravity-defying drainage systems and untraditional dump sites. Some macerating pumps even feature water hookups. These unique elements enable RV owners to flush out stubborn leftovers in their waste black and gray tanks.
Types of RV Macerator Pumps
A portable pump is a small motorized device that attaches directly to the waste outlet on the bottom of a recreational vehicle holding tank. Portable macerator pumps typically connect directly to a vehicle battery. Users can attach an outlet or garden pipe to drain their solid and liquid effluent after it has been churned into sludge. All models reviewed in this list are portable RV macerator pumps.
Permanent RV macerator pumps work in the same way as portable pumps. However, they are typically hardwired and not intended to be removed and reinstalled regularly. These elements function a lot like sink garbage disposal units. Only, their job is to grind up human sewage and paper products rather than food scraps.
Last but not least, 100-volt macerating pumps offer more power and efficiency. These RV macerator pump systems tend to be pricier than portable or permanent models. However, they also speed up sewage removal.

Important Considerations When Buying an RV Sewage Pump
You need to consider all your requirements before settling on a specific type. Some pumps are small and portable. Meanwhile, others are hefty and powerful. Some pumps can crush and dispose of solid sewage over long distances. Whereas, others struggle to defy gravity. Ask yourself how often you will use your macerating unit? Will you be dumping effluent in unconventional locations? Will your recreational vehicle be parked downhill from dump stations? Take all this into consideration when choosing a product.
Ease of Use/Installation
Most consumers prefer pumps that are easy to install with color-coded power cords. Most RV macerator pumps must be clamped onto the outlets of RV waste tanks. The outlet should be compatible with a garden or drainage hose and connections watertight and obvious. Make sure your macerating unit also comes with a clear set of installation instructions.
Does it come with accessories, or do you need to buy them separately?
Some pumps include all the essential accessories, including couplings, hoses, and wires. However, other pumps don’t include any. Make sure that any add-ons are durable and made to last. Also, check to see if the unit can be paired with a standard garden pipeline.
Some pumps can only be used with proprietary hoses. Accessories such as these are typically more challenging to access. Usually, these accessories can only be purchased online so if you have an issue you can’t just run to your local hardware store for a quick fix.
Pro-tip: Consider investing in a clear elbow hose attachment. This is a see-through piece of plastic piping that you can attach. Using such a device allows you to see when there is no more slurry exiting your black tank.
It’s never a good idea to cut corners when it comes to waste management. Still, there are macerating pumps for all budgets. Set clear expectations and do not exceed the limits of your budget. You should be able to find an adequate solution for any budget.
Pump Strength/Flow Rate
Pump strength is given in gallons per minute. A powerful pumping system will save you time. The most powerful option we came across was capable of dispersing 15 gallons of effluent in just a few minutes. A powerful maceration unit will also help you defy gravity. If you’re constantly pumping uphill or around obstacles, a high flow rate is essential.
RV Macerator Pump FAQ
Q: How far can a macerator pump?
These devices can send (formerly solid) sewage as far as 150 feet. Of course, not all consumers want to store and handle a 150-foot waste outlet hose. Find a pump and hose pairing that meets your basic distance requirements.
Q: What kind of hose should I use?
Most people prefer to use standard 1-inch garden hoses with their unit. Since macerator pumps turn solids into sludge, the effluent has no issue traveling down the narrow diameter of a garden hose. These hoses are also very easy to clean and store. However, a garden water pipe requires a threaded outlet. If your macerating unit demands a proprietary hose, so be it.
Q: How do I use an RV macerating pump?
In most cases, you can connect your macerating device directly to your RV wastage tank. After that, connect a drainage hose. Finally, press the power button. Make sure that the drainage hose is fed directly into a dump station, toilet, or another suitable sewage system. The sewage will be churned into a slurry and sent down the hose. Let the unit run through a complete cycle. Turn it off when waste stops flowing and effluent ceases to exit the drainage hose.
Q: How do I maintain my macerator pump?
Experts recommend using toilet cleaner and macerator descaler to remove solids from macerating pumps. Of course, regular household vinegar is an excellent alternative. Insert the cleaning fluids into your RV toilet and flush the contents. Turn your pump on for a couple of seconds and allow the chemicals to enter. Allow the chemicals to loosen any stuck-on dirt and grime. In a few hours, add some water to the waste tank and turn the pump on again. Then, allow it to run through a complete cycle.
