What You Should Know Before Buying macerator pumps

Flow rate and pressure

The flow rate of a sewage pump determines its efficiency. The ideal flow rate for the sewage pump that you use for your house or RV depends on the amount of waste produced. Additionally, to gauge what flow rate your sewage pump should have, you must know the number of drains and users feeding your sewage basin. This can help you identify the best flow rate for your space. Typically, a good sewage pump has a flow rate of about 50 gallons per day per person.

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.

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 macerator pumps

How do I maintain a macerator pump?

Macerator pumps need to be cleaned on a regular basis to maintain them. It’s best to clean a macerator pump once a month in areas with hard water and once every three months in areas with soft water. You can use a brand-specific cleaner and descaler to clean it out or use home remedies like a white vinegar and water solution. It is important to note that you must disconnect the pump before proceeding with the cleaning. Allow it to dry out for at least two hours before reconnecting the power supply and flush with clean water.

How long do RV sewage pumps last?

Macerator pumps, which grind waste, last up to 10 years. However, this is contingent on how it is used and maintained. The more frequently the macerator is used, the less effective it will be at its job. In addition, if you clean your macerator regularly, the machine’s life span extends.

What happens if ejector pump fails?

If your ejector pump fails, the flushed sewage and solid waste can accumulate in the pipes. Built-up waste creates pressure and causes the pipes to burst. The bursting happens at the lowest point, like the basement in homes and the base level of the RV. You are likely to have a sewage leaking event which is the first and often only indicator of ejector pump failure.
