Want to let you know that I missed a step in setting up at a rv park .I forgot to run the water at the hose bib hookup , and an earwig must have been getting a drink when I screwed on the hose .Well it impeded the water flow to the toilet , by ending up in the flush valve . So $37 bucks and about an hours fun latter . Be sure your water hose bib and your hose are clear of bugs
