    I was under the house last night doing to insulation work. I was checking out the water lines and their routing and I got really confused. Water comes into the house from the ground at the center of the house, then branches off. One goes and supplies the house with water, the other goes to the far side of the house, to a valve, turns to flexible plastic pipe then back into the ground. I did not mess with the valve. I remember it being on, though I can not tell for sure. What is this branch for?

    It is not the sprinkler or outside water, I know where those are.

    Do you have a well or city water?

    That was my guess, an old well line.

    City water. Pretty sure it has always been city water.

    But that line is an OUT line. I should go check again if the valve is open or close

    Could this be for circulating in the winter to prevent freeze-up - not sure where you are but in the north, where there are exposed lines or extreme cold

    It does get cold where I am at. 28 last night. So this line then ties into the main in. You crack the valve and it keeps the water circulating to prevent freezing. Interesting. But this would not prevent the supply lines that feed the house from freezing as this circuit is the first branch.

    I was thinking about the well comment. I guess it could also be an "IN' line tot he house water system.

    Was there once an outbuilding on the property? Maybe they piped fresh water to it.

    If there was a freeze relief valve, it wouldn't (or shouldn't) be in the crawl space. There are much easier ways. I would be trying to open/close the valve and see what happens.

    Turn the valve off and see what happens. You are on city water, so you should have pressure and never need to prime a pump.

    If your neighbor comes out and says his shower just stopped, you know what it is :lol3

    Now that you mention it, my water usage has been a bit high for a couple of months and my neighbor has been endlessly wet-sanding an old Dakota he bought on the cheap. I have an inside shutoff for that sillcock, so maybe I'll turn that off to see if my usage goes back down. (Besides, it's almost time to turn it off for the season anyway.)

    It is always good to get/keep up close and personal with the underside of your house. Seriously. Its always good to see whats going on.

    Once a year at least.

    Previous line for a Koi pond or fake creek or waterfall that's long gone from previous owner?

    Ok I think I figured it out, it is a drain line.

    Was under the house yesterday and storing some summer gear. Thought about the line again so I went to mess with it.

    The valve on the extra line was open. I opened it and closed it several times, while allowing time between it. It seems like there is not water/pressure in the line. the plastic hose runs down into the vapor barrier. I notice allot of white hard water deposited like staining on the cinder block foundation at the edge of the vapor barrier near this hose/pipe. So I rip a small opening in the vapor barrier to see what is underneath. A wet towel/rag!!!

    What I think is going on is when you shut off the main water coming into the house the lines in the hose self drain out of a relief valve. The draining water is suppose to drain through this extra line. It doesn't do the best job as the draining water sprays out right at the shut off valve. But some water must travel down this extra water pipe and into a pit of some sort.

    I was not please to find the wet rag underneath the vapor barrier. I did not want to mess with that crap unless I was all geared up. Looks like I need to pull up the vapor barrier and make sure the pit is draining well. Did not see heavy molding, but imagine there could/should be.

    Something to look forward to. GREAT!!!

    What is a condensate drain?

    T & P. Temperature and Pressure. The water heater discharge is in the garage.

    Anyone have experience with this type of drain. Seems like something is going to have to be done. But what??

    Not sure. It was built in the 70's in a rather permanent year round neighborhood. No one would ever mistake Truckee as a place that did not get cold in the winter. Several times a year we get the "prize" for being the coldest place in the nation, as well as the highest snow fall. But who knows what the builders were thinking. It is a fairly simple "shoebox" of a house that would seem perfectly placed in the suburbs of Sacramento.

    This house has always been a permanent residence prior to me buying it 5 years ago.

    Condensate drain comes from an air conditioner. Humidity in the air condenses as it cools when crossing the coil. It is collected in an internal pan and drained off via pipe to ???
