titlted frost-free sillcock
Inspired by Trader, I'm again looking into a frost-free sillcock.
The text and video pages seem to make a big deal out of tilting the pipe down 5 degrees as opposed to up 5 degrees. Up is not the alternative in my case, it is level. All the pipes are already there and the pipe that goes outside is level. If I do nothing, the new sillcock will be level too. It seems to me that if the pipe I.D. is 1/2 inch, a level pipe will drain until the water level is no more than 1/8", 1/4 of the total diameter, and that even if it freezes then, it will expand UP into the air space. And that 1/8" of water, or even 3/16" with all that empty space above can't possibly freeze in a way that breaks the pipe. Won't it just lift itself up? Clower to the center of the pipe. (I reed that water expands a bit more than 9% when cooling between 4^C and 0^C.) Maybe at the end of the pipe, where the valve is, surface tension will keep the water level higher, but that will be 6" into my basement, where the temp is always about 68^. Can water freeze inside when it's 68F outside. I don't see how I can raise the other pipes to tip the sillcock down as it goes out of the house. IIRC, a floor joist is in the way. |

Doesn't matter, level or tilted down. Tilted up and holding water is the only real problem installation - or leaving a hose attached. |
