Recap: The Best RV Macerator Pumps

Buying a New RV Macerator Pump: What to Look For

Here’s what to look for when your RV needs a new macerator pump.

The Type of Macerator Pump You Need

All RV macerator pumps are designed to do the same thing: grind up waste for easy removal. While they all technically do it the same way, there are three different types of RV macerator pumps. The three different kinds are portable pumps, permanent pumps, and 110V pumps.

Permanent pumps are the right choice if your RV already has a designated space for them. They can be more expensive and may require an expert to install them. Portable pumps are the most versatile choice. There are a lot of options as far as size and price. A 110V macerator pump is costly, but usually much faster than portable or permanent pumps.

Can It Pump Uphill

The ability to pump uphill is one of the key benefits when purchasing an RV macerator pump. If gravity is not doing the waste removal work fast enough for you, you are not alone! Because this is such a common problem, pumping uphill is almost always included as a feature on most RV macerator pumps.

Once you have confirmed that the RV macerator pump you are considering can pump uphill, there are additional factors to consider. You may want to consider the speed at which the pump removes waste and the length of the hose included. If you intend on pumping waste up a large incline, make sure you get something with enough power to handle it.


If you choose a permanent macerator pump, you can always pay to have someone else install your RV macerator system. But involving a professional can get expensive; first, you have to buy an elaborate system, then you have to pay for installation and professional upkeep. It can add up quickly and leave you unable to tackle small problems as they arise.

If you go with a portable or 110V RV macerator, countless DIY options come with a much lower price tag and varying levels of involvement from you.

Some of the do-it-yourself RV macerator systems will come fully equipped. These systems will include all the attachments you may need. Some systems require more legwork on your part. Both of these systems are much more hands-on than permanent pumps, but there are many resources available to help you figure it out.

Extra Features Included

You are buying an RV macerator pump to do one thing. Make waste removal less painful. Not all pumps are created equal, and many features can make your life easier.

Thermal protection means the pump will automatically shut off if it starts to get overheated. Some pumps have stainless steel blades and shafts so that the inner pieces won’t rust. A pump that self-primes saves you time when emptying the tank. Some RV maceration pumps have automatic flushing or an on/off remote.

Adding additional features may cost you more money in your initial investment, but they can pay off in other ways.


Waste removal is one of the most unpleasant aspects of RV living, so anything that makes it easier is a win. There are a lot of good RV macerator pumps out there to meet your RV’s sewer needs, no matter your budget.

Frequently Asked Questions

How Long Do Macerator Pumps Last?

Macerators last about 10 years. This depends on maintenance and usage. The more you use your macerator, the less effective it will be. If you clean your macerator often, you will increase the life span of your pump.

How Far Will A Macerator Pump?

This depends greatly on the horsepower of your pump. Higher horsepower pumps can pump up to 200 feet while smaller pumps will just pump about 20-30 feet. This also depends on if you are on a level surface. If you are downhill your pump might pump a little bit farther, and vice versa if you are pumping uphill.

Does A Macerator Need To Be Vented?

This depends on the type of pump. Check with your provider to see if your pump needs a vent and how to best install it.
