The advice to camp on your own property for a few days is very sound. I hooked up the shore water to the TT to test the plumbing out. After about 20 minutes there was this strange sound coming from inside the TT. Went in, looked around, saw nothing unusual. Lifted the toilet cover and looking straight down into the toilet noticed the water level was at the brim. What would any boy do? Flushed of course. Have you ever seen Old Faithful? Water shot out of the toilet going 63 1/4 miles per hour hitting me in the forehead on the way to the ceiling. Stunned, I staggered backwards. If that was not education enough, since there was still water in the toilet it was flushed again. Hit in the head again. Water was now flowing down the aisle and out the door. Hollered for help from DW who showed up proclaiming ?I wish I had a camera. I wish I had a camera?. Well, as the seasoned rv?ers already know, I connected the water to the sewer clean out port instead of the shore water port. Lesson learned, and a few more. The price of the TT was worth my DW telling this story.
