Anderson was the dominant diver in the boys’ D category at the top event, which not only attracted most of Britain’s best but also divers from America, Ireland and Dubai.
The Plymouth youngster won gold in the one-metre and three-metre disciplines and took silver in the five-metre final.
There was also a bronze medal for Plymothian Shanice Lobb in the girls’ A+ platform competition.
Lobb, now competing for London Aquatics Club, finished behind Leeds’ Phoebe Banks and Southampton’s Gemma McArthur in a strong women’s platform field.
Plymouth Diving’s Cody Powell-Tuckett finished 10th in that event, which attracted 24 competitors.
Olympic synchro medallist Dan Goodfellow did return to action following injury, but only in the three-metre springboard, where he won a silver medal, ahead of the likes of Ross Haslam, Freddie Woodward and James Heatly.
Plymouth took a young team to the West Yorkshire event. As well as Anderson and Powell-Tuckett, Morgan Boyd, Ben Armitage, Thomas Davies, Josh Freeman, Ben Bluett, Evie McCabe, Maria Marasescu and Frances Burdett were among their team to make the long trip to Leeds.
