That means the two o-rings need to be replaced.
Generally they need to be replaced almost every fill or every other fill.
From Jaggedfury's pb thread "The O rings are easily replacecable. It's like .58 cents per 3-6 O rings. Part number at Lowes is BrassCraft # 0533. The size is 1/4"ID x 3/8"OD x 1/16" Wall Thickness."
Hope this helps!
