Your review: I used this tape to insulate the manifold that connects the well tank to the pump, gauges, relief valve, spigot, pipe to house. You can do a neater job with tubular pipe insulation if you use different sizes of insulation and miter the joints.
Pros: Good quality product. I was able to stop the pipes from sweating.
Cons: Hard to insulate elbows and around fittings without overlapping. Can't remove without leaving glue on the pipe. Hard to do a neat job.
