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!
