A macerating pump can grind waste and discharge it through small pipes, making it an economical and practical solution for adding a new bathroom. However, can any toilet be used with a macerating pump?
The answer is clear: NO.
Here are three reasons why:
1. Compatibility with Rear-Discharge Toilets Only
Macerating toilets, also known as up-flush toilets, operate by directing waste and water into a pump when flushed. The pump's grinding mechanism turns solid waste into a slurry, which is then discharged through a small-diameter pipe into the main sewage line. This means only toilets with a rear discharge outlet can connect to a macerating pump. Traditional gravity-flush floor drain toilets cannot be connected to a pump.
2. Matching Pipe Diameters
The outer diameter of the toilet's discharge pipe must match the inner diameter of the pump's inlet. If there’s a significant size difference, gaps may form during installation, leading to potential leaks after flushing. Therefore, it’s essential to ensure that the toilet’s discharge outlet fits snugly with the pump's inlet, ideally with the help of Teflon tape or clamps for a secure connection.
3. Efficient and Worry-Free Drainage
Several factors influence this, such as the height difference between the toilet discharge and the pump inlet, the type of extension pipe used, and whether the pump's power is sufficient to handle the flushing volume. Different manufacturers produce toilets and pumps with varying performance characteristics, so it's crucial to confirm compatibility with the seller before making a purchase!
