Black Tank Valve

[marielw824]

Hey ... haven't been around in a long while ... but am wondering if ANYONE has EVER come across a broken/damaged black tank valve. Apparently, the plastic flap that closes the tank has been broken/chipped, if you will. So we've had the valve replaced. But just wondering if it something others have come across and maybe why? Thanks!

Can someone explain this 'cable' to me? In my mind, a cable is thin and flexible. So how is it stiff/firm enough to close the flapper on the valve?

Think like a brake cable on a bike

since this is sort of a related question I'll throw it in here....

How long are the cables usually to the valve? I assume they're probably a little different model to model but generally what are we talking? 2-3 feet or 5-6 feet? Reason I ask is I want to lube mine and I'm wondering if I can drop some oil in the sleeve and blow it back far enough with compressed air to coat the whole cable?

It's closed. The dealership dropped the underbelly (so they've told me ... haven't picked it up yet), and didn't cut the underbelly.

Is your RV's underbelly closed or exposed?
