In this article, we’ll explain what a macerator pump is, discuss its benefits, provide a step-by-step guide on how to use it, and answer some frequently asked questions.
What’s a Macerator Pump?
A macerator pump is a specialized device designed to break down solid waste into tiny particles, allowing it to be pumped through small hoses and pipes. This makes it possible to empty the tanks of your RV quickly and easily, even over long distances. 
Why do you need an RV macerator pump?
An RV macerator pump is a convenient and efficient way to empty out your recreational vehicle’s gray and black water tanks. This type of pump grinds up solid waste into a slurry that can be easily pumped out through a garden hose or other disposal system. With an RV macerator pump, you can quickly and easily dispose of your RV’s waste without having to manually empty tanks. 
Easy Steps to use a 120V RV macerator pump
Connect the pump to the black tank
The first step in using a 120V RV macerator pump is to connect it to the black tank. You will need an adapter or connector that fits both the pump and the black tank outlet. Once you’ve connected them, you should check for any leaks along the connecting line before plugging in the power cord. 
Attach the hosepipe
Next, attach the hosepipe to the pump. Make sure that it is securely connected and that there are no leaks. Some RV macerator pumps have a self-priming feature which means you don’t need to do any preparation in order for them to work properly. 
Arrange the power supply
Once you’ve connected the pump and hosepipe, it’s time to arrange the power supply. You need to make sure that your RV macerator pump is plugged into an electrical outlet with sufficient voltage. If you are using an extension cord, make sure that it is long enough and of appropriate gauge for the job. 
Operate the pump
Now you are ready to operate the pump. Make sure that the switch is set to ‘on’, then press and hold the start button for a few seconds. The pump should now start running and will begin pumping out waste from your black tank. 
Turn Off the RV macerator pump
Once the macerator pump has finished pumping waste from your black tank, it’s time to turn off the pump. Make sure that you unplug the power cord before disconnecting all hoses and adapters. Store them in a safe, dry place until you are ready to use them again. 
Cleaning of sewer hose and macerator
After each use, it is important to clean both the sewer hose and macerator pump. Disconnect all connections and rinse off the hoses with clean water before allowing them to air-dry. You can also use a mild detergent or cleaner to help remove any residue that may have accumulated during your RV trip. 
Why would you use a 120VAC macerator instead of a 12VDC?
Using a 120VAC macerator instead of a 12VDC is the best choice for RVs since it can handle larger volumes of waste and has greater power than the 12VDC pump. It will also work better in colder temperatures since they are more efficient than their DC counterparts. The downside is that you need to have an AC power source available to run it, which may not always be feasible in certain situations. 
Is it necessary to flush the RV black tank during emptying?
Yes, it is important to flush the RV black tank during emptying. This helps reduce odors and prevents clogs in the plumbing system. The recommended way to do this is with a macerator pump, also known as a 120 Volt RV Macerator Pump. This type of pump grinds up human waste into small particles for easy transportation, and also has the power to push it up a hose connected to your RV.
To effectively flush the black tank using a 120 Volt RV Macerator Pump, follow these simple steps:
- Connect the macerator pump’s inlet hose to your RV’s black tank outlet pipe.
- Connect the macerator pump’s outlet hose to your RV’s sewage holding tank.
- Open both valves on the macerator pump and make sure that it is securely connected to a 120 Volt power outlet.
- Make sure that all other wastewater tanks are closed and unable to draw water away from the macerator pump.
- Turn the macerator pump on and let it run until all of the waste has been emptied from your RV black tank.
- Once the process is complete, turn off the macerator pump and disconnect both hoses from their respective tanks.
- Disconnect the power outlet and store the macerator pump in a safe, dry place. 
Can running a macerator result in a blown-out fuse?
Yes, running a macerator can result in a blown-out fuse. This is because the amount of electricity used by a macerator is usually greater than what most RV power sources can handle. It’s important to check your vehicle’s manual to determine how much voltage it can handle and make sure that the pump you choose matches that amount. Additionally, pay attention to the wattage of your pump and never exceed the maximum wattage rating for your vehicle. Lastly, it’s always a good idea to add a surge protector before plugging in any electronic equipment. This will protect your RV from potential power surges that could result in an overloaded fuse. 
How often do you use a macerator to clean the black tank?
It’s a great idea to use the macerator pump once every time you empty your black tank. Doing so ensures that all of the solid waste is fully broken down and pumped out of your RV. However, it’s important to remember not to overuse the macerator pump as this can cause problems with your plumbing system. 
What is the order of macerating black and grey tanks?
When using a 120 Volt RV Macerator Pump, it’s best to start with the black tank. This is because the contents of the black tank generally contain more solid matter than those in the grey tank and could potentially clog up your macerator pump if left until last. Once you have emptied out your black tank, move on to the grey tank. When you are finished, be sure to run some clean water through the macerator pump in order to flush out any remaining particles and keep your pump in good working order. 
Additional Lessons Learned
Get a Clear Elbow
When you’re dealing with a 120 volt RV macerator pump, there’s bound to be quite a bit of waste that needs to go out. To make sure it goes out safely and efficiently, get yourself a clear elbow for the waste outlet. This will help keep your pump clean and extend its life. 
It’s important to backflush often when using a 120 volt RV macerator pump. This will help keep the pump clean and running efficiently by getting rid of any waste buildup. It also helps to extend the life of your pump. To backflush, simply reverse the flow of water through the macerator and let it run for a few minutes. 
In addition to backflushing, you’ll want to top-flush your pump often. This will help keep the macerator working properly and ensure that it’s getting rid of any waste effectively. To do this, simply run a small amount of water through the pump while it’s in use. 
Pre-Grind As Necessary
If your pump isn’t able to process larger pieces of waste, you may need to pre-grind it. This will help the pump break down any debris that is too large for it to handle on its own. To do this, use a grinding tool or even just a pair of scissors to cut the waste into smaller pieces before putting it into the macerator. 
Keep Fuses Handy
Finally, it’s always a good idea to keep some spare fuses handy. This will help ensure that your 120 volt RV macerator pump stays running even if it trips the fuse. It’s also a good idea to check the fuse every now and then to make sure it doesn’t need replacing. 
Gray Tanks = No Problem
If you’re using the macerator pump to empty out your gray tanks, make sure the outlet is facing downwards before turning on the pump. This will help ensure that all of the waste is properly drained out. Additionally, when you turn off the pump, don’t forget to close the valve at the bottom of tank. This will help prevent any waste from flowing back in. 
How do RV macerator toilets work?
RV macerator toilets are designed to break down solid waste into a liquid form, so it can be easily discharged and processed. To do this, they use an electric motor to operate a blade that grinds the solids into tiny particles, which then pass through the pump and out of your RV’s plumbing system. This process makes it easier to dispose of the waste, since it can be discharged directly into a septic tank or even a sewer system.
How many amps does a macerator pump use?
Most 120-volt RV macerator pumps require between 3 to 5 amps of power. If you have an inverter in your RV, you may be able to use a higher powered pump that uses up to 10 amps.
