Re: [A/S] Leaking black tank valve




 We had the same problem, and bought an "RV Hydroflush," available from most 
dealers.  "Flushes out holding tanks and sewer hoses.  Clear plastic shows you 
when your tank and hose are clean.  Includes hi-flow shut-off valve and 
anti-siphon valve.  Replacement valves available.  Priced $22.39"  Ugh!  Dale 
does the dirty work!  As Hunter suggested, our problem was caused by 
paper.ShirleyIn a message dated 10/29/2004 12:24:49 PM Eastern Standard Time,

Just worn out?It could be something is caught, like toilet paper. You might try 
some Thetford TP dissolver before you try changing valves...... I used it once, 
it's a two day operation IIRC.Hunter
