We have a pool sweep that is attached to a pump through a heavy-duty garden hose (that's what the installer recommended). Last week, after about five years of use, the hose broke. We lost about 6 inches of water from the pool before my wife noticed the problem.

The hose tubing is fine -- the fitting at the pump end broke away from the hose. Apparently the vibration from the pump stressed the metal until it failed. I'm looking for suggestions to prevent the same thing from happening again.
