Macerator Toilet Problems Troubleshooting Guide


If you own a macerator toilet, you may have encountered some issues along the way. From clogs to strange noises, these problems can be frustrating and inconvenient. However, fear not! In this article, we will provide you with a comprehensive troubleshooting guide to help you overcome macerator toilet problems. Whether you are a DIY enthusiast or simply want to understand the intricacies of your macerator toilet, this guide will equip you with the knowledge you need to tackle any issue that may arise.

Understanding Macerator Toilets

Before we delve into troubleshooting, let’s first understand what a macerator toilet is. A macerator toilet is a type of toilet that features a built-in macerator pump, which finely grinds waste and toilet paper into a slurry that can be easily pumped through small pipes. This design allows for flexibility in plumbing installations, making it possible to have a toilet in areas where traditional plumbing is not feasible.

Common Macerator Toilet Problems and Solutions

1. Clogs and Blockages

One of the most common problems faced by macerator toilet owners is clogs and blockages. These can occur due to various reasons, such as flushing items that are not toilet paper-friendly or a buildup of debris in the macerator pump. Here are some steps you can take to address this issue:

Solution 1: Check for any visible blockages. Start by turning off the power to the macerator toilet and removing the access panel. Inspect the macerator pump and pipes for any obstructions. If you find any, carefully remove them using gloves or a tool.

Solution 2: Use a plunger. Similar to a regular toilet, you can try using a plunger to dislodge the clog. Ensure that the macerator pump is turned off before attempting this method. Plunge vigorously, but be cautious not to damage the macerator pump.

Solution 3: Clean the macerator pump. Over time, debris and waste can accumulate in the macerator pump, leading to clogs. To clean it, turn off the power to the macerator toilet and remove the access panel. Use a brush or cloth to remove any residue from the pump blades. You can also consider using a macerator cleaner solution, following the manufacturer’s instructions.

2. Unusual Noises

If you notice strange noises coming from your macerator toilet, it may indicate an underlying problem. Here are some common noises and their potential causes:

Noise 1: Grinding or rattling noise. This noise is usually an indication that there is an obstruction in the macerator pump or pipes. Follow the steps outlined in the previous section to check for and remove any blockages.

Noise 2: Whirring or humming noise. A whirring or humming noise could indicate a faulty motor or impeller in the macerator pump. In such cases, it is advisable to contact a professional for repairs or replacement.

3. Pump Failure

In rare cases, the macerator pump may fail to operate, resulting in a non-functioning toilet. Here’s what you can do if you experience pump failure:

Check the power supply: Ensure that the macerator toilet is properly connected to a power source. Check the circuit breaker or fuse box to ensure the power supply is not disrupted.

Inspect the float switch: The float switch is responsible for activating the macerator pump when the water level rises. If the float switch is stuck or damaged, it may cause pump failure. Check the float switch and ensure it moves freely without any obstructions.

Contact a professional: If the above steps do not resolve the issue, it is advisable to contact a professional plumber or the manufacturer’s customer service for assistance. They will be able to diagnose the problem and recommend the appropriate solution.


In conclusion, macerator toilets offer a convenient and flexible solution for plumbing needs. However, like any other appliance, they can encounter issues from time to time. By following the troubleshooting guide outlined in this article, you can quickly identify and address common macerator toilet problems. Remember to always prioritize safety and, when in doubt, seek professional assistance. With the knowledge gained from this guide, you can confidently navigate the world of macerator toilets and ensure the optimal functioning of your bathroom fixtures.
