We used it once last year to clean & flush out the black tank. The end did not loosen or get lost in the tank but once it hung up trying to pull it out. So in the future I intend to add a clamp to insure the tip does not come off like others have had happen. But it appears to be firmly held in place. Turned out our grey tank seemed more dirty than the black tank which means past owners of the 22 year old RV ignored it and only focused on the black tank. However a good device to help insure the tank stays cleaned out.
Do you have a question about this RV Waste Valve?

Thank you for your feedback. I reached out to the manufacturer and was advised that the Hydroflush it is best used when there is a straight drain line from the valve cap to the tank opening If you have bends or curves in the drain lines to the tank opening sometimes it is better to use the Flush King part # F02-4350. This has a valve they can close and fill up the tank to clean it out, and then release the water by opening the valve in the Flush King.
