What is a Macerator Pump?
Like mentioned above, the macerator pump is a piece of kit that will turn larger chunks of waste into smaller pieces or a slurry of waste. This slurry can then easily pass through your hose into the sewage system. A decent pump will provide your hose with enough pressure to travel uphill and eliminates the struggle of getting the waste out of your tanks.
Aspects to Consider When Buying an RV Macerator Pump
Every brand will make its macerators differently. There are also many factors you’ll need to consider when buying your pump. The different benefits and downsides that come with every pump. The following list will be the different aspects to consider and what makes an excellent macerator pump.
Does it Pump Uphill?
Many features make a great pump, this uphill pump function is one of them. Picture the scene, you’ve parked up on the only available spot on the camping site, you need to empty your waste tanks but the only available sewage connection is uphill, but your pump can’t provide the pressure needed to carry out such a task. The same also applies if you need to empty the tank, but you’re not anywhere near a connection point, you can empty your tank into a secondary tank built into your RV.
Some macerators will take a lot to hook up to your RV. These devices are electrically operated; therefore you’ll need to connect it to your battery via the RV’s circuit. You could also connect it to an external secondary battery that you can use whenever you are cleaning out the tanks. An extra battery would be the best option as you won’t be unloading the waste too much, it would save a lot of hassle.
Manufacturers have two options, provide a simple and basic macerator pump that has minimal features. Or, create a pump that not only does its job flawlessly and provides you with extra value features like a water cleanout system. This feature will allow you to connect a water hose to the pump and flush out the extra slurry liquid from your tanks, ultimately cleaning your tanks as well.
