Glad I had it in my RV
This is one of those things that you may only use from time to time. But boy, when you need one you’ll pat yourself on the back for having it, or kick yourself for not having purchased one.
First time I used it we were at a really nice RV report. The 4” sewer pipe at our site had been broken one one side such that the regulator connector for our sewer line would not securely attach. This baby came in very handy. Was patting myself on the back for purchasing an item I might never use again.
