In November 2017, the Duplex Pipe Organ and Blower Company, under the direction of James Richardson-Jones, undertook the rebulding of a major wind reservoir.  The new tops to the wind reservoir were manufactured offsite in the Duplex workshop and then transported to the church for fitting.  The base of the original large wind reservoir was retained, and the new tops added with mechnisms to provide two more easily maintained reservoirs than the original large one.
