Camco RhinoFLEX 6-in-1 RV Sewer Wrench | Compatible with 3-Inch and 4-Inch Male or Female Sewer Clean-Out Plugs, Slotted or Flush Sewer Plugs, and All 4-in-1 Adapters (39755)

I have been searching for a clean out key for soooooo long. This is a must have. First let me say, this is not the end all tool as there are plenty of clean outs this does not work for. And for those we have sledgehammers and pliers. But for the average plastics clean out old it works great.

I bought this to tighten a 3 inch Zurn countersink plug I also bought on Amazon.I was surprised the Camco wrench didn’t fit. In Canada I have only ever seen the non-countersunk plugsthat you can tighten with a regular adjustable wrench. I ended up just using pliers turned sidewise to tighten the Zurn plug.

We are active RV campers, and we own a 27ft travel trailer. We carry this tool with us in our "sewer kit" and we have used it More than once.The wrench is lightweight and it's durable. I highly recommend this as an essential RV tool to have.Real example. After attaching our sewer line to the hookups provided, we stayed in our campsite for 5 days. With some wild fluctuations in temperature, the sewer hookup end to the trailer tightened up. It would not come off with my hands. The wrench took that off in seconds. Note: this had happened once before I had made this purchase. I said never again!

Very nice to have. Certainly helps with a tighter fit

It works as intended. It is obvious;y not a very strong wrench but I bought it only for servicing the septic treatment system, where it will not experience heavy loading.
