Hi all - we have a 2006 SR 340DA that we bought new. We've babied it and had very good luck with everything over the years. The toilet has always worked perfectly but on a cruise this past Saturday we had a boat load of people and our guess is that too many people used too much marine grade toilet paper and the toilet won't flush anymore. The bowl holds water when the peddle is pressed down although the ball value opens and we can hear the vacuum pump going. It appears that the line to the holding tank is plugged and is holding water as well. We just pumped out the tank so that's empty. Our repair guy told us to call a plumber but my guess is they would just try to snake the clog. This seems like something I can do myself? I have a 10 foot springy metal pipe snake I could run down it. I can duct tape the pedal down so it stays open during this operation. Is this the way to go on this or should I do something else? Thank you!!
