What You Should Know Before Buying RV macerator pumps
Benefits of having a macerator pump
A macerator pump is a subtype of a sewage pump. It is the kind of pump that is used to transform solid sewage into liquid so that it can conveniently be pumped from bathrooms, basements, and crawlspaces into the septic tank. They are quite beneficial in that they act as a quick, easy, and cost-friendly solution of getting the waste out of your house/RV and regulating your sewage system. Macerator pumps are the best option if you want to fix the sewage in your bathroom or basement but don’t want to commit to serious remodelling of your house. These are the kind of sewage pumps that are most commonly found in RVs because they are great when you are parked downhill and also less messy than standard hoses.
Permanent VS Portable pumps
Sewage pumps come with both portable and permanent options. If you live in your own house and have no plans of moving any time soon, then a permanently installed sewage pump seems to be the most favorable option. However, if you have opted for the installation of a sewage pump only temporarily, then you should get a portable sewage pump that is only semi-permanent. Essentially, a portable sewage pump is a relatively smaller commitment and hence is perfect if you are not sure about using the sewage pump for an extended time period, which also makes it perfect for RVs.
Macerator pump noise
It is not normal for a macerator to make very loud noises. Macerator pumps are about as loud as a normal flushing sound, so if your pump is making a noise that exceeds that standard, there is something wrong with the pump. Usually, such a dysfunction is caused by something being stuck inside the blade mechanism of the pump. In order to get the pump in working order again, the foreign object must be removed (ideally by a service engineer).
Questions and Answers About RV macerator pumps
Why does my sewage pump smell?
Sewage pumps can smell bad because of a clog or a waste backup in the tanks. You can smell waste if the valves have been left open and the waste has dried up in the black water tanks on the sides or the bottom. On the other hand, the sewage pump can smell bad in some homes because of stagnant water in the basin or a sewage infiltration beneath the foundation because of a broken sewer line.
Can a RV macerator pump uphill?
Yes, it can. Macerator pumps, whether installed in homes or RVs, are also called ‘lifting stations’ by some plumbers. They are built to move solid matter uphill by macerating or grinding waste into small pieces and flushing dirty water away. Strong pumps can move waste uphill as far as 150 feet.
Can I drive RV with water pump on?
Ideally no. It is a risk to drive the RV with the water pump on. If you leave it on, it can overflow the gray tank and pump itself dry, leaking into the coach. Traveling along bumpy roads can cause the sink or shower to turn on by accident which can lead to flooding as well. On the other hand, some water pumps are loud, which can be annoying and distracting for some drivers, but this depends from person to person.
Can I put a bigger water pump in my RV?
This is contingent on the space you have. If the current installation in your RV fits in snugly, it is not possible to opt for a tank with a large water capacity as it will be larger in size. It isn’t easy to install a pump if the space is tight. You also need to consider flow rate and maximum water pressure specifications before installing another pump in the RV. These are indicated in the owner’s manual.
