DL Mechanical is a Nottingham-based business specialising in plumbing and pipe fitting engineering services. The company works with a broad portfolio of clients in the commercial and educational sectors designing, engineering and installing new pipework for water, steam & condense, oil and gas, soil and vent, rainwater among a range of other services.  

An FE college in Nottinghamshire called on DL Mechanical’s expertise to advise on a change of use project that would improve the facilities for mechanics apprentices. Changing a classroom to a workshop required the installation of a wash down area. A site survey confirmed that no drains were in the immediate vicinity of the required area, so an alternative solution was found. 

With advice from local plumbers’ merchant, Willbond, a Saniflo Sanispeed+ grey water lifting station was specified to discharge the water from the new washdown area. With its robust 400-watt motor and low activation level of 95mm, the unit was connected to a Zip water heater and the washdown areas to discharge hot and cold waste water through small bore pipework up 3m to an adjoining pipe. This ran by gravity to a soil and vent pipe some 60m away.

Terry Fisher, mechanical contracts manager at DL Mechanical, oversaw the project;

“The Sanispeed+ pretty much enabled the project to go ahead. Bar drilling a bore hole – which would have been prohibitively expensive – a pumped solution was the only way forward. The Saniflo unit is a simple plug and play solution, so proved easy to install and it has been working efficiently and  effectively from day one.”

The Sanispeed+ is ideal for pumping waste water from appliances and sinks in light commercial applications and with four inlets it connects to a range of appliances. It has a working temperature of 35°C but can handle temperatures up to 75°C for short periods. It has a quiet motor and can be installed below counters or in cupboards out of sight if required.
