The FPS Iguazu Sump Foul is our standard 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 50 sewage pump, with a maximum flow rate of 330 litres per minute and a maximum rated head of 7 metres.
The vortex impeller passes solids up to 50mm. For a typical domestic foul duty it is the often the right size, and is the best value in the range.
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 to drain void spaces, and to manage external water and low-lying areas where gravity drainage is not viable.
Choosing between the three foul stations:
Bigger is not automatically better. A pump with far more capacity than the inflow empties the chamber quickly and switches on and off too often, and that short cycling shortens pump life. The float switch fills and empties the chamber on a sensible cycle when the station is correctly matched to the duty.
The EVAK Hippo 50 has a maximum flow rate of 330 litres per minute and a maximum rated head of 7 metres.
These are the two ends of the pump curve rather than a single duty point: at 7 metres the flow has fallen to zero, and the full 330 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.
Full pump performance figures are in the specification table further down this page.
Often installed internally or externally. 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.
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.
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 includes an external installation at a property where patio doors had a limited threshold and were exposed to flooding. Gravity drainage was not possible, because the area sat lower than the discharge point and roof drainage had no formal connection, so the Iguazu Foul provided the solution. The video shows the site before installation, with photographs afterwards. It has operated reliably for many years since, and the finished installation is discreet, with minimal visual impact.
Used regularly, the Sump Foul 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.
