Bought my first home just recently and had to shut of mater main to fix a leaking bathtub tap. Main shutoff is in the crawlspace and I noticed a lot of water droplets all along the pipe (almost side by side drops) While it isn't 'raining' drops from the pipe I'm concerned enough to ask you guys!
I had previously noticed the same large amount of water drops along the pipe leading into my water heater but I had assumed that was because the heater was under load at the time and may have been just new cold water running through a warm pipe.
Actually now, with the dishwasher running, the pipe to the heater doesn't have visible drops forming but it is wet to the touch.
Sooooo, my question is - Is this something I should be concerned about or is it normal ? There doesn't _appear_ to have been any damage from this moisture but I would assume any moisture _can_ be damaging.
Would insulating the pipe be the smart thing to do? I could do that in the crawlspace easy enough but once it punches through the floor it is hidden behind the drywall in a very tight area for several feet before entering the water heater.
details : - 40 yr old rancher - Vancouver Island, BC - temp stays above freezing mostly but for some cold nights occasionally - crawlspace with 1/2 dirt 1/2 cement floor isn't directly heated but stays fairly warm through ambient heat - 10-15yr old water heater (near end of life I know but not rusted out, might need to be drained though)
TIA
