 This caused the widening of the River Taff which moved eastwards towards the spring with floodwaters often covering the spring "Rhondda Cynnon Taff Council".The well building fell into disrepair at the beginning of World War I, and in 1929 the Taffs Well villagers decided to repair the well and it re-opened in 1930 complete with a small swimming pool.It was around this time that the famous travel writer H. V. Morton  visited the well dedicating several pages of his 1932 book to the well.
