What is a Macerator Pump?

Because RVs are mobile, they use holding tanks to collect waste and black water from the toilet. You can use the typical stinky slinky to remove it as Cousin Eddie did in the National Lampoon movie, or you can use the best RV macerator pump.

RV macerator pumps grind up the solids and liquids from your tank, which makes it easier for them to travel through the hose.

Here are some more reasons to consider using the best RV macerator pump instead of a traditional hose.

  • You can drain uphill because the grinder does the work instead of gravity
  • The slurry can drain for longer distances and through smaller hoses
  • It reduces odors
  • You can dump in more places, including a residential sewer drain if it’s legal in your area
  • It allows you to dry camp in areas without sewers

How to Use a Macerator Pump

Using the best RV macerator pump for your situation isn’t difficult. In fact, with a few easy steps, you can hook up the pump and remove all the waste from your tank.

Here is a step-by-step process for using the best RV macerator pump.

  • Find your RV’s sewer drain point and attach the macerator pump to it
  • Next, attach the exit hose to the pump
  • Place the other end of the hose into the receptacle area such as a toilet or sewer drain pipe
  • Now, hook up the macerator pump to your 12V battery
  • Pull and open up your tank draining valve
  • Push the “on” button on the pump
  • Continue to run the pump until the flow of slurry stops.
  • Turn off the pump

Not so difficult, is it? Here’s a video for those of you who are more visually-minded:

What to Consider Before Buying the Best Macerator Pump

Before you run out and buy the best RV macerator pump for your RV, you should know a few things about the process that will make the process easier.

Can you see through those elbows?

There is no polite way to put this, so here goes: you need to see what you’re pumping out of your RV. That’s right when you use the best RV macerator pump you need to have eyes on all those solids and liquid waste for a couple of reasons.

They are:

  • You have to see when the pump is dry, so you turn it off — otherwise, it will burn out.
  • You need to see what’s in the hose before it reaches the pump
  • When you backflush, you need to see the results

To get this view, you can use a clear elbow designed specifically for this purpose.

  • 45 degree swivel fitting
  • Clear fitting to see if holding tank is empty
  • Swivel lug and bayonet fitting for secure connection

Once isn’t enough

When you open the drain on your tank, the liquids will naturally come out first. Once the liquid is gone, the solids will begin to leave the tank. But here’s the deal: you’re not going to get them all out with one effort.

And that’s where backflushing comes in.

Once the macerator pump runs dry, hook up the hose to the black tank drain valve and run clear water in it to loosen up the solids. Then, hook up the best RV macerator pump again and watch the clear elbow until it runs dry again.

You may have to do this several times until the tank is properly cleaned out. You will know when this happens because you will see clear water running through the clear elbow.

Do it from the other end, too

In addition to backflushing, you should also top flush. To do this, close the black tank drain valve and then from the interior of your RV, allow the tank to fill up. Be sure to turn it off before it overfills. Then pull the black drain handle, hook up the best RV macerator pump and turn it on. It will flush from the top, which is another way to get at all that slurry that doesn’t want to come out the easy way.

Be the garbage disposal

For those of you who have delicate sensitivities, you may want to skip this section. But if you want to truly clean your black tank with the best RV macerator pump, this is a necessary step.
The idea is to pre-grind all of the solid waste in your tank. Here’s how to do it.

If large clumps of solids go through your macerator pump, it can make it overheat and cause damage. And that’s why it’s important to pre-grind. When you see a large clump of solids approaching the clear elbow, turn off your pump. Next, turn on the backflushing valve.
Allow that pressure to break up the solid and then turn off the back flush. Now, you can turn the RV macerator pump back on.

Eew, right? But if you’re going to be a road warrior, you have to learn to deal with your waste, and these tips and tricks for the best RV macerator pump will go a long way in helping you do that.

Commitment phobic or not?

Finally, you will need to decide whether or buy a portable macerator pump or a permanent one.
A portable RV macerator is for those rigs that don’t have a macerator in the bay or a dedicated sewer bin area. Portable macerator pumps run on 12V batteries.

A permanent RV macerator has base installations so you can install it underneath your rig. They also run on 12V batteries.
