Unfortunately, that resource is geared toward northern folks who routinely face that kind of hazard, not those of us in Houston who face this predicament only rarely and whose houses are built "inside out" relative to houses in many parts of America (in other words, our houses are designed to retain coolness, not heat, and they are configured accordingly).
|Your home could vary tremendously from what I'm showing here, but the basic principles should be the same. If your home is newer, somewhere inside it you will find a water supply manifold (older homes may have just a single line coming in and then branching off from there). Ours was a Meritage built in 2009/2010, and so our water lines are made of PEX, but I believe most of the Brightons in Section 9 have PVC pipes (looks like white plastic). |
In this photo showing our house in "stick stage" before drywall was put up, you can see the back side of the manifold (child for scale). Red means hot water lines, and blue means cold water lines. But notice that both run from manifold into the attic above, where they are not insulated.
|If you live in Centerpointe, your water meter is on your front lawn and it looks a lot like this. There are little grooves in the outer edge of the cap. It can be popped off using a screw driver.|
You could potentially get into trouble if you accidentally mess up your water meter, your main incoming valve, or the line. You could also get into a heap of trouble if your water line freezes and splits. Every once in a while, life invites us to pick our poison, eh?
|How cold is it right now?? Well, this was my bird bath this morning. Bye bye subtropics, at least for a few days.|
