Product Information

Full details

The FlowPro FP400K is an ideal solution for homeowners and installers looking to add plumbing facilities in locations where conventional gravity-fed drainage is impossible, such as basement conversions or remote utility rooms. It offers the key benefit of flexible installation by pumping waste through small-bore piping, though it is specifically designed for grey water management and should not be used as a replacement for a toilet macerator handling black water.

FAQs

Can I connect a toilet to the FP400K?

No, the FP400K is designed specifically for grey water (sinks, showers, washing machines) and cannot process solids typically associated with toilet waste.

What is the maximum temperature of water it can handle?

The unit is designed for standard household drainage temperatures, but avoid pumping boiling water directly into the unit to protect the internal seals.

Does the unit need to be vented?

Yes, proper venting is required to ensure the unit operates at peak efficiency and prevents airlocks within the system.

How often should I service the unit?

It is recommended to inspect the unit annually for scale buildup and clear any potential debris from the inlets.

Can the unit be installed inside a kitchen cupboard?

Yes, its compact design makes it ideal for under-cabinet installation, provided there is adequate access for future maintenance.

Troubleshooting

The unit does not activate when water enters.

Check the power supply connection and ensure the circuit breaker has not tripped. Also, inspect the inlet for any blockages.

Water drains slowly or backs up.

Check the outlet pipe for blockages or kinks. Ensure the non-return valve is not obstructed.

Excessive noise or vibration during use.

Ensure the unit is level and firmly secured. Check for hard objects trapped in the maceration chamber.

Pros and Cons

Pros

  • Extremely versatile for multiple appliance types
  • High-performance pumping capacity for horizontal and vertical runs
  • Quiet motor operation avoids noise disturbance
  • Compact design fits easily into tight spaces under sinks or behind cabinets
  • 2-year manufacturer warranty for peace of mind

Cons

  • Not suitable for black water or toilet waste applications
  • Requires access to a power supply near the installation site
  • Annual maintenance recommended to ensure long-term performance

Setup, Compatibility & Care

Installation should be performed in accordance with local building codes. Ensure the unit is placed on a level surface and secured to prevent vibration. Use non-return valves on all inlet pipes to prevent backflow.

For care, flush the system periodically with a dedicated macerator descaler to prevent scale buildup on the blades and sensor. Avoid pouring harsh chemicals, grease, or large food scraps into the connected sinks, as these can impede the macerator's performance or cause motor strain.
