The energetic Bulls side had the majority of possession and pinned the Seals in their own half for large swathes of the first half.
Aaron Downes’s side went a goal up thanks to Billy Philips, with great work from Keziah Martin and Aaron Skinner in the build up.
But five minutes from half time, Billy Waters converted Tom Peers’ wayward ball and despite offside protests, seeing Kyle Howkins hooked, Chester pulled themselves back level.
