I tried to save a little money when I bought my RV. The parts people were showing me all these sewer hoses and I didn’t know any better. She kept telling me about this higher dollar hose but I went with the cheap one. About two weeks later, on a very hot July Louisiana morning I got up to use the restroom. I noticed that the black tank is full light was on so I went outside to pull the plunger…as I was taught. Well, the cheap hose blew off and I was standing in some stuff you definitely don’t want to be standing in on a hot Louisiana morning…lol. Buy the good hose !!
