Best RV Macerator Pump: Make Disposal Easier

Dumping sewage can be a major hassle when your traveling by RV. Sometimes dump stations are located on top of a hill. Sometimes your solid effluent is too dense to make it through a gravity-fed system. What's more, sometimes they are no dump stations! Standard gravity-fed sewage lines don't always cut it. That's why most RV owners eventually add aftermarket macerator pumps to their rigs. 

These incredible units slice and dice through solid waste, turning it into an easy-to-remove sludge. We took the time to identify seven of the best macerator pumps on the market. We also have included our unbiased review of the top maceration pump. Dive right in to discover the benefits of these incredible RV accessories. With the right macerator, you'll be able to flush your RV toilet without having to worry about the aftermath.

What Is a Macerator Pump & How Does a Macerator Work?

Macerator pumps grind up solid sewage. Macerated sewage can travel faster and more efficiently than solids. They are also useful at eliminating clogs and other messy drainage issues. These impressive aftermarket devices enable RV owners to pump their solid effluent through regular garden pipes.

Unlike firm sewage, the macerated slurry is not as impeded by gravitational forces and density differences as regular human waste. As such, a good product also help to eliminate otherwise prohibitive hazards, such as hilly landscaping and awkwardly positioned dump stations. Since these pumps grind sewage so well, they enable travelers to dump their RV sewage into private sewers and toilets.

What are the Benefits of Owning an RV Waste Pump

For many travelers, an aftermarket sewage elimination system is key to an enjoyable RV experience. An untimely solid waste issue can put a significant damper on your road trip. Typically, they are easy to install and operate. Most of them connect directly to RV batteries or generators. They use a nominal amount of energy to slice and dice through thick effluent products.

In doing so, they enable RV owners to overcome otherwise prohibitive obstacles, such as gravity-defying drainage systems and untraditional dump sites. Some macerator pumps even feature water hookups. These unique elements enable RV owners to flush out the stubborn leftovers in their gray and black waste tanks.

Types of RV Macerator Pumps

Portable RV Macerator Pump

A portable RV macerator is a small motorized device that attaches directly to the outlet on the bottom of an RV holding tank. A portable RV macerator pump 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. 

Permanent RV Macerator Pump

Permanent RV macerator pumps work the same way as the portable ones. However, they are typically hardwired. What’s more, they are not intended to be removed and reinstalled regularly. These elements function a lot like sink garbage disposals. Only, their job is to grind up human sewage and paper products rather than food scraps.

110-Volt Macerator Pump

Last but not least, 100-volt macerator pumps offer more power and efficiency. These systems tend to be pricier than portable and permanent macerators. However, they also speed up sewage removal.

Important Considerations When Buying an RV Sewage Pump

Type

You need to consider all of your requirements before settling on a specific type of model. 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 macerator pump. Will you be dumping effluent in unconventional locations? Will your RV be parked downhill from dump stations? Take everything into consideration when choosing a product. 

Ease of Use/Installation

Most consumers prefer pumps that are easy to install. What’s more, most pumps must be clamped onto the outlets of RV waste tanks. The power cords should be color-coded. The outlet should be compatible with a garden or drainage hose. The connections should be watertight and obvious. Make sure your pump 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 do not include any additional accessories. Make sure that add-ons are durable and made to last. Check to see if a pump 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. If you have an issue, you cannot 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.

Cost

It’s never a good idea to cut corners when it comes to waste management. Still, there are macerator 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.

Pump Strength/Rate

Pump strength is given in gallons per minute. A powerful pump system will save you time. The most powerful pump we came across was capable of dispersing 15 gallons of effluent in just a couple minutes. A powerful pump will help you defy gravity. If you’re constantly pumping uphill or around obstacles, a high pump rate is essential. 

Best 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 outlet hose. Find a pump and hose pairing that meets your basic distance requirements.

Q: What kind of hose should I use for a macerator pump?

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 macerator pump demands a proprietary hose, so be it. 

Q: How do I use an RV macerator pump?

In most cases, you can connect your macerator pump directly to your RV waste 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 pump run through a complete cycle. Turn it off when the effluent ceases to exit the drainage hose. 

Q: How do I maintain my RV macerator pump?

Experts recommend using toilet cleaner and macerator descaler to remove solids from macerator 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. Allow the chemicals to enter the pump. Allow the chemicals to loosen the stuck-on dirt and grime. In a few hours, add some water to the waste tank. Turn the pump on again. Then, allow it to run through a complete cycle.
