We were just about ready to leave our campground for a long Thanksgiving weekend at our daughter's house 5 hours away and DW says why is the toilet filled to the brim? Played with the peddle for a bit and yup, that Thetford curse.
So, I shut the water off (which I had planned to do anyway) and we went on our way. Leave it till we get back on Sunday.
So, Sunday we're back and I look it over carefully and if I let the peddle snap back it will usually shut off. If we operate using onboard FW we can shut the pump off in between flushes and I'll look for a toilet in the morning.
Monday morning start looking for a Dometic 320. Camping World has one in white about 1/2 hour away, but I'd really prefer bone. DW says just fix it. I call a couple other RV places and bingo, Pete's RV in North Charleston has one in bone and he's only 15 minutes away. I get there and not only is their price the same as both CW and Amazon but it's on sale at 50% off.
So double blessing. We caught the problem before it flooded the fiver and I got it fixed for half price.
Both DW and I really like this 320 over the Aqua-flush. Don't know why I waited so long to make the change after all the threads I've read on this forum.
But after shopping around I know why Keystone uses the Thetford instead of the a Dometic, they're 100 bucks cheaper.
