See what’s coming out your sewer hose to be sure you’re done

By Chris Dougherty

Dumping your holding tanks is as much about art as science. If you want to know if your tanks are absolutely clean, the only way to know is to be able to visualize what’s coming out.

Okay, I know this sounds gross — and it is! But please believe me, if you have a blockage or some other issue because your tank isn’t cleaned out, it becomes a lot grosser!

So, here’s Part One of my system, the clear sewer hose adapters. Available in various lengths and angles, the clear adapter by Camco lets you see what is coming out of your tanks. When you flush them — and you should especially flush the black tank — clear water coming out means the tank is clean. Problem averted.

These are really easy to use as they just connect in-line with any sewer hose. If your sewer connection is recessed and hard to reach, there are various lengths available to eliminate the need to crawl or reach way under the coach. Valterra offers adapters with 45- and 90-degree bends which are useful in certain conditions where the direction of the hose dictates it.

In part two, I’ll cover tank flushing systems. Many of you already have them, as manufacturers have been building them into RVs for years. But in case you don’t have one, we’ll show you what you need to install one or use one of the portable options out there.
