Good Stuff!
I had drained my tanks so that I could replace a few gaskets and such. After reassembly my drain valves were very hard to operate. Gently closed the valves and added the drain lubricant to my tanks from inside toilet and sinks. I then added a few gallons of water to the grey and black tanks. The next day on draining the system the valves operated as new. Great product!

Does as it claims
Had some sticky tank release valves on my holding tanks on my RV. Followed the directions and it cleared them up. Saved me the task of trying to remove and replace them. One of the valves was so deep I would have had to remove most of the system just to get to it. It was a life saver. Worked great on rejuvenating the toilet valve too.
