Dump Valves Sticking

[Ramblin Ron]

My dump valves do not leak and open and close fairly easily, but they stick a little when opened or closed. So, I think they need some sort of lubrication. I'd like to find a tank additive that would take care of this. There are commercial dump valve lubricants available. I've also read that coconut oil would work well for this purpose, What works well?

I always found that spraying lubricant on the extended pull rods tends to resolve sticking issues -- worth a try.

I sprayed pure silicone on the pull rods.
