The FPS Iguazu Sump Foul Pro is a packaged sewage pump station for foul water from basements and ground floor extensions where gravity drainage is not possible. It pairs a 190 litre high-grade MDPE chamber with the EVAK Hippo 100 sewage pump, with a maximum flow rate of 480 litres per minute and a maximum rated head of 11 metres. The vortex impeller passes solids up to 50mm. It is the higher-capacity of our two cast iron foul stations, and the one to choose where the discharge run is long or the lift is high.
A common application is collecting foul water from a W.C. or utility room and discharging it to the main sewer. A typical example is the foul sewage from an annex, a garden room or a property extension.
It is also used in flood defence systems and to manage external water where gravity drainage is not viable.
Choosing between the three foul stations:
It is worth sizing this properly rather than buying the biggest. A pump with far more capacity than the inflow will empty the chamber quickly and switch on and off too often, and that short cycling shortens pump life.
Due to the higher power draw of the EVAK Hippo 100, this system cannot be used with a battery backup.
The EVAK Hippo 100 has a maximum flow rate of 480 litres per minute and a maximum rated head of 11 metres. The pump uses a vortex impeller for 50mm free passage.
These are the two ends of the pump curve rather than a single duty point: at 11 metres the flow has fallen to zero, and the full 480 litres per minute is only available with no lift at all. What you actually get sits between the two, where the curve meets the resistance of your pipework. Our pump performance calculator works that out for your pipe run, and how to read a pump curve explains the principle.
The EVAK Hippo 100 is a robust, cost‑effective sewage pump designed for everyday domestic and light‑commercial foul water applications. With 50mm solids handling, strong lift performance, and durable construction, it provides reliable operation without the complexity or cost of cutter or grinder pumps.
Full pump performance figures are in the specification table further down this page.
Can be installed internally or externally. Depending on the desired installation, these chambers are often connected with fixed PVC delivery pipe, or with suction and delivery hose, matched to the outlet size.
The chamber outlet terminates in a 2 inch male BSP thread, and the station is designed to pump through a 63mm pump main. Alternatively, use 50mm (2 inch) suction and delivery hose. The hose option is made up from three parts: a hose tail, the hose, and a hose clip. The gallery shows the system connected with 50mm delivery hose buried underground for a tidy, concealed finish.
When installed internally, the chamber would usually be fitted with a recessed, sealed lid, allowing the surrounding floor finish to be continued across it while helping to contain odours and moisture.
Supplied as a complete plug and play unit, ready for installation. Some on-site work is required, including reconnecting components, drilling entry holes for cables and routing wiring through a suitable conduit. Read our guide to installing a sump pump.
Images are indicative only. Photographs may show optional extras, accessories or pipework that are not included in this listing, and the chamber is shown cut open in some images to reveal the internal components. Your chamber is supplied whole. Please refer to the specification and the list of what is included above.
The gallery shows installations using grey solvent weld pipework (which we do not supply) and others using our green suction and delivery hose. You can see the system installed in a garage floor for flood water removal, and externally as a pumped drainage system, both finished with a discreet lid. In the garage installation, if water enters through the walls or floor even with a flood barrier in place, the station removes it automatically.
Used regularly, the Foul Pro needs very little maintenance. The hardest condition for any pump is standing unused for long periods in damp conditions, which can cause components to seize, so run it periodically.
Where a system will be used infrequently, the stainless Sump FEKA is often the better choice.
The gallery includes a short maintenance video.
Pump station design and installation is site specific. You should always consult a suitably qualified engineer to determine the correct configuration and installation method for your application, and a qualified electrician for the electrical connection.
Installing or altering foul drainage in England falls under Building Regulations, and Approved Document H is the guidance used to demonstrate compliance, including sizing the chamber around the number of people served. See sewage pumps and Building Regulations explained, and confirm the position for your project with your local building control body.
We supply equipment. We do not provide site-specific design or installation advice over the phone. Where a project needs calculations, a specification or a design, see our engineering review service.

Watch below as we install a Packaged Pump Station into a garage floor, to assist with removing any floodwater that may enter.
In this instance, the property was suffering some water ingress into the garage through the walls, and also through a non-FPS Flood barrier.
The Sump Pump was installed into the garage floor to provide a passive solution to remove water from the garage.
