I haven't taken my valves apart to manually lube them yet. I have used this product during storage (between trips) and so far so good. It is much easier than taking the valve apart and manually placing lubricant in it. I have had this RV for a couple of years using this routinely between trips and have had no issues yet. I use it (following the instructions) in my grey and black water tanks. Keeping in mind that I have obviously not crawled into my tanks to see this product work, it does seem to be helping me avoid any
valve problems, so I would recommend it.
