7 Best RV Macerator Pump To Make Dumping Waste Easier

A Macerator pump is a crucial component in an RV as it handles the waste disposal system, sparing you from manual tasks. While many RVs come with built-in waste storage tanks, emptying them requires access to a dedicated disposal center, which may not always be convenient. Equipped with blades, it grinds waste into smaller pieces, facilitating disposal in public toilets. 

Here are key factors to consider before purchasing a macerator pump:

  • Power Type: Most electronic devices come in two types: corded electric and portable battery-powered. This factor not only affects the reliability of the devices but also their applicability regarding various tasks. When considering a macerator pump, be sure to choose between these two options before making a decision.    
  • Flow Rate: The flow rate of a pump indicates how much it can discharge per unit of time. In simpler terms, it’s the speed at which the pump operates, whether it’s for an RV water pump or a macerator pump. Opting for a faster pump is generally preferable as it can empty the tank more quickly.    
  • Supported Accessories: Regardless of the pump you purchase, you’ll need several accessories for it to function properly. If you already own some accessories like plug extenders or a hose, make sure they are compatible with the macerator pump you intend to buy.

RV accessories need to be thoroughly verified before you can buy them, especially the ones that are needed for crucial applications like waste management systems. It is important that you pick one of the best options for such an accessory as a macerator pump in order to get the best experience with your trips. So, we are bringing you the best macerator pumps that you can find on the market right now along with their specifications and a helpful “Buying Guide” to help with your purchase.

Buying Guide For The Best RV Macerator Pump

While some RV accessories are very easy to buy, some require thorough research and shortlisting from hundreds of options that look somewhat similar. A macerator pump belongs to the second category since these are complicated devices that are not easily understandable, especially for someone who is buying a pump for the first time.

Therefore, we are going to discuss some of the most important features of a macerator pump in our buying guide today so that you won’t have to browse through hundreds of options to understand the product. You can simply check these factors on a macerator pump and decide if they are good enough for your application or not.

1. Overall Product Quality

A lot of users tend to go with an option that appears first when they start looking for a macerator pump. While there are chances that you may stumble upon a great product at the first glance, it is wise to not leave this to fate and check the quality of the product before buying it.

A macerator pump is something that has to be a high-quality unit if you are expecting a couple of years of hassle-free performance from the unit. However, there are a lot of macerator pumps that can break down within a couple of months due to bad components or product quality. To save you from such options, we have shortlisted the best options right here.

2. Maximum Flow Rate

While you are buying a pump, the first thing that you should check is its flow rate. Whether you are buying a regular pump or a macerator pump for your RV, its flow rate is going to represent its operation speed and how fast it can discharge the output.

Since the macerator pump deals with wastage from your RVs, and waste tank, you would want it to be as fast as possible so that it can empty out the tank quickly. However, some options offer a high-speed performance, but can’t deal with excessive pressure. So, if your RV has a rather large waste tank, you probably need a more capable macerator pump that might work at a slow pace but gets the job done without any problem.

3. Voltage Compatibility

When you are powering the macerator pump from your RV, you need to keep in mind that the voltage rating of the pump should be compatible with the voltage rating of the plug where you are connecting it. Otherwise, the pump may not function properly or even cause a short circuit.

A lot of users prefer to use a generator in their RV which is what you will need for powering devices like a TV, refrigerator, water heater, or a macerator pump. So, what you need to do is check the outlets on your generator, or rather the voltage rating on these outlets and make sure that they have a compatible voltage rating for your macerator pump. If not, you will need an additional adapter or cable extender before you can start using a corded electric RV macerator pump.

4. Power Type

One of the best things that have happened to electronic devices in the last few years is the addition of the battery-powered category to even some of the most power-hungry appliances. Nowadays, you can find a portable battery-powered option for almost all types of electrical devices, even a macerator pump. As you can imagine, having a battery-powered macerator pump is ideal for an RV where an electric power supply is usually scarce.

Instead of needing to find a power outlet or use excessive power from your generator, you can go with a battery-powered macerator pump and use it whenever required to avoid excessive power usage. But, keep in mind that battery-powered macerator pumps are best suited for smaller tanks with less pressure. Due to the lack of continuous power supply, the battery of the pump may run out before emptying a large tank.

RV Macerator Pump – FAQs

1. How does a macerator pump work?

Ans: Even though RV macerator pumps might look a little bit complicated from the outside, their working principle is not that difficult. In fact, an RV macerator pump works in a similar fashion as a disposal system in your kitchen sink. It basically breaks down the larger volumes of waste into smaller pieces and passes it out through a hose. Thus, the smaller volumes of the waste can be dumped in any public disposal place like a public toilet or a sewer.

2. What is the range of a macerator pump?

Ans: You will be surprised to know that despite the compact form factor of a macerator pump, most of these units are capable of pushing the wastage nearly 100 feet away from the pump. Some premium options can even do 150 feet, making it much easier to reach the disposal location without having to park your RV around one. Even if you are going with a short-range option, make sure that it has at least 50 feet range to be on the safe side.

3. Is it necessary to clean the pump?

Ans: As you can imagine, an RV macerator pump is going to deal with wastage throughout the year and problems like blockages are bound to happen. To avoid that, you should clean a macerator pump at least once every year. However, you can always run the pump with clean water every other week or so to clean it internally. This will further reduce the chances of blockage and make the pump last much longer.

4. Why do I need an RV Macerator Pump?

Ans: RV Macerator Pumps offer a more convenient and sanitary way to empty your RV’s holding tanks. They can pump waste over longer distances and through smaller diameter hoses, providing flexibility in choosing dump station locations.                                                                                                                     

5. Can I use an RV Macerator Pump for both black and gray water tanks?

Ans: Yes, most RV Macerator Pumps are designed to handle both black (toilet waste) and gray (shower and sink water) tanks. However, always check the product specifications to ensure compatibility.
