Dry Risers Direct carrying out Hydrant Flow and Pressure tests for the Rotherhithe Tunnel

Here’s a Dry Risers / Hydrants Direct Ltd van carrying out the Hydrant Flow and Pressure tests for the Rotherhithe Tunnel under the River Thames on behalf of Transport for London (TfL). The tunnels are closed to traffic on Monday nights between 10 p.m. and 5 a.m. to allow safety critical testing to take place. The Blackwall north and south tunnels are next on the schedule. We currently undertake Hydrant (and Dry/Wet Riser) testing for Schools, Prisons, Business Parks, Universities, Hospitals and other privately owned and managed properties.
