Studor Active Ventilation @ The National Lift Tower July 2015 Update

I can hardly believe it, but it’s now been 10 weeks since we launched our “Seeing is Believing” test rig – the past weeks have been an absolute flurry of activity! The response to our offer to visit the test tower and witness/participate in the testing has been overwhelming, on both a national and international level.

Test Tower Ready to Flush

Ready to Flush!

Our latest live demonstration event last week was attended by over 60 Public Health Engineers over 4 days, ranging from time-served to the newest batch of our future engineers. Also present to support me with running the event were Steve White (Studor Technical Director), Daniel Rath (Studor Technical Sales Director), Michael Chang (Studor Product Engineer) and Tom Gale (Studor General Assistant).

If you missed this event, then don’t worry – we will be back at the tower in September – and if you’d like to come up then please email me at

The results and reactions, even from those slightly “long in the tooth”(!), were all similar to the previous shows:

  • “Wow!”
  • “I think I have got it wrong in the past!”
  • “I’ll have to look at my designs more closely from now on!”
  • “I wouldn’t want to be sat on that, if that happens!” – this was specifically in response to witnessing the following video when 10 WCs were flushed with the Studor System isolated (with no venting).

During the hands-on testing, anyone attending will take an active role in the tests, from loading the WCs at the top of the stack, watching the AAVs working at the midway point, viewing the annular flow through clear sections of pipework, seeing the P.A.P.A. attenuating (slowing down) the positive transient and, at the base of the stack, witnessing the hydraulic jump and the speed of the solids against the delayed water flow. A member of the Studor team is available at all stages of the testing to answer any questions. What is a very important aspect of our events is that if anyone wishes to see one of the tests done in particular way, then we will do our utmost to accommodate any requests.


Actively vented shoes!

On a final note, one of our visitors last week misunderstood “active ventilation” and thought it related to her footwear – by far the best safety shoes so far on the test tower, although we have been advised that this is the safest nail varnish colour to have! 🙂
