Hi Tom,

I recently had my vacuflush and holding tank system worked on by the 
"Prince of Porcelain" in Sidney BC.  Among other issues, my holding tank 
lights were working oddly.  He removed the cap to the holding tank (in 
the bilge just forward of the engine).  It was clear that the floats on 
the tank level probes were badly corroded, and partly eaten away.  They 
no longer floated up and down well, and one was eaten away enough that 
even when it moved it could not properly activate the light indicating 
waste level. Since separate probes are used to activate the different 
lights, I wonder if it's possible that one of your probes is corroded.

I have not yet done it, but he said I could get a replacement set of 
probes from Marine Sanitation in Seattle. Sealand part SLB 230930
