Before you think I have a typo in my title, feel free to look closely at the picture of this product. I spelled it the way they spelled it: **Solder Seal Plumber's Heat Pruf Grease** I purchased this plumber's grease when we had a whole house water filter put on our main water line. The water here sometimes turns orange or yellow. The water pipes in this area of the county seem to be long overdue to be replaced and they seem to have problems adequately flushing the lines after they open them for repairs. It's frustrating, to say the least. The plumber recommended that we use some of this plumber's grease to place around the top edge of the outer housing for the water filter so that it would be easier to tighten and loosen. It does seem to do the job pretty well. I haven't had problems tightening or loosening the equipment. It is a little hard for me to figure out exactly how much grease to use. I think less is better when working with water pipes because you wouldn't want to have too much and have it oozing into your drinking water, which I didn't have happen, but I could easily see someone doing that. The grease seemed a bit pricey to me. It kind of resembles a cross between the lard my grandmother used to keep for cooking fried foods and petroleum jelly. There's not much in the container, but it will last a long time as well. We ended up removing our water filter because it was causing even more problems than it was helping, so we're back to the drawing board with gross water and buying bottled water for the kids to drink. **My Viewpoint:** Solder Seal Plumber's Heat Pruf Grease seems to work pretty well at lubricating a joint. It seems a bit high priced to me, but it seems to do what it is supposed to do. I'm not sure how this compares to other lubricants that aren't intended for plumbing. I'm not so sure there is much of a difference. Maybe it's all just marketing strategies of the same basic product. I'll give this one a solid three since it does seem to work.
