Inline and Duckbill Webinars, Lunch and Learns

What we cover

Why flap valves fail and what it costs to keep them running. How rubber duckbill and inline check valves behave differently in silt, saltwater and submerged conditions. How to size and specify a replacement, including cracking pressure, headloss and what the dimensional tables do not tell you. Where the tricky retrofits are, and how they get done on live assets.

We have been talking to engineers about failing flap valves since 1989 — at trade stands, in meeting rooms, and now online. The sessions are free, technical, and have nothing to sell you at the end. Bring your worst outfall.
