Why does the hot water hose to my washing machine keep unscrewing late at night?
My 7 month old washing machine had the hot water hose simply unscrew itself from the wall 2 nights ago. We managed to wake up, abate the flood, and fix. I screwed hose back, and used plumbing wrench to tighten. Very tight. Last night- it unscrewed itself in middle of night AGAIN! What could cause a hose to unscrew itself? Hose was very tight, unmovable. Worked great after install and tighten. How can a hose unscrew itself 2 times in the middle of the night? Could cold-night expansion/contraction with the fittings be it, and if so, would replacing the hoses with better quality ones do the trick?
