I've been in the garage tonight looking at the iron pipe I purchased. It is coated in orange primer on the outside as standard nowadays due to many plumbers complaining they have to spray it themselves. Upon closer inspection I noticed the inside of the pipe to be painted grey. This grey paint could prevent it from rusting internally. So all is not lost.
I suppose having spent a small fortune on this pipe, I might as well use it. If it does give me trouble later on then I'll strip it out and install copper. In hindsight copper would have been better because its easier to work with. I also wouldn't of had to spend more money on a pipe threading kit. Oh well you live and learn.
Anyone know what kind of oil is used to lubricate when threading a pipe manually? Don't say pipe threading oil
I wonder if I can get away with a little engine oil?
