So, our old house in Gainesville has been sitting empty, on the market since may. We finally have a guy willing to buy it, so we went up to turn al the utilities back on.

The first thing we go to do, is turn on the water. We go open up the water meter and open it's valve, and we have a geyser at the house valve. turns out a foot of iron pipe corroded out at the house valve. so 1 trip to home depot (13 miles each way). We replace the house valve, and both iron pipes that link it from the meter line to the house.

So we fix that, and go open the valve for the hot water heater. Instantly, we heard water in the wall of my bathroom. We go dig out some plank runners and crawl under the porch, through the mud, uncover the hot water line, just to find, it's broke up inside the wall. Then my girlfriend's mom dropped her off.

Turns out, there's a reason that there is a patch in the entryway wall, behind my sink. We use a knife to break the paint and drywall tape, and find a hot water pipe that has shatered in 3 pieces- on the verticle (sheared/shatered), on the angle (shattered), and on the horizontal to the valve (shattered). So trip 2 to home depot, with girlfriend.

We get back, replace everything starting at 4" below where the verticle shattered. While we let all the PVC glue dry an such, I go looking at the other hot water valves. We turn the cold water back on but leave the hot water cut off, and find out that the flexline from the stop valve to the sink on the hot side, also cracked. So a third trip to home depot ensued, this time we bought 2 of everything they made in CPVC, or so it seemed. Then when we got back, it finally donned on us that we still had to check the shop. The flexline between the stop valve and the sink for the hot side also cracked in there, but we didn't bother to fix it and risk breaking another stop valve.

After finally fixing everything, we sealed up the house, all 3 of us went to dinner, then we took my girlfriend home. When we got to her family's complex, My girlfriend and I were afraid he's get disgusted by the living conditions, but rather, he started gawking at all the classic cars that are laying in the tal weeds, just asking to be restored. Among the inventory, are 2 1940-1950's plymouths both with all the chrome in tact, a 50's Willy's panel wagon, 2 or 3 Chevy Vega's, amd a bunch more that we didnt even have time to see. I'd never really noticed them, they were just cars that lined the 1/4 mile long winding driveway.

So we spend $100 in CPVC stuff, plus the gas to go 100 miles each way the house, and 3 trips at 26 miles round trip.

Now if we can just get the thing off our back.


Where the right angle exploded going into my bathroom.

Yeah, we've been down that road, too. Only we had to tear half the outside wall off the barn to get at the break --- a tiny pinhole in the crease of a T joint.
 
Here's the story for those of you who don't deal with freezing weather on a regular basis. When a pipe bursts from freezing, it's not the ice that bursts it.

Here's what happens. We all know that water doesn't compress. When the pipe gets below freezing, ice will form. So who cares. Well, the ice is less dense than water, but so long as that water can move out of the way, no harm is done. Even when the ice completely fills the pipe, the ice isn't able to exert enough pressure on the pipe wall to rupture it. So why did my pipe burst you ask? And more importantly ... why did it break in the middle of an interior wall inside the house? When the ice forms a plug, the pipe wall restricts it from growing radially, so it grows laterally, along the pipe. There, a millimeter of growth can cause thousands of psi to be exerted on any closed section of pipe. THAT is what blows out the pipe, and it can let go with one helluva bang. For that reason, the best way to avoid ruptured pipes is to leave all the taps dribble a little. Not only does running water have a much harder time freezing ... as the pipe freezes, the restriction trying to form the plug speeds up the water flowing past it, making it progressively harder and harder to complete the plug. And even if the plug should manage to form, and you're talking some serious cold at this point ... the open taps provide pressure relief.
