This was a source of dispute for some years, with legal action instituted by both sides and the occasional bout of vandalism to ensure water actually flowed to the Plymouth works. The situation was eased with the opening of the Merthyr Tramroad, as there was less traffic on the upper section, and therefore less water used by the locks.
