Danco Cartridge Repair Kit for Delta Single Handle Faucets 86971
So I’m leaving this note for myself. The Danco replacement kit 86971
with stainless steel ball valve you get at Lowes or Home Depot contains 2 sets of springs and gaskets, but has no information on which one to use. Since my gaskets were worn out. I had no idea. After playing around with it I’ve decided my old 1985 vintage shower ball valve uses the short cone shaped springs and the short gaskets from the set…
I’ve left this here for my future reference. If it helps you in some way, that is an optimal outcome… :)
