Other causes of ectropion are scarring, burns, trauma (called cicatricial ectropion), spasm of the orbicularis muscle, which may affect either the upper or lower eyelid, or paralysis of the orbicularis muscle in which only the lower eyelid is affected.
It is possible that there is nothing wrong with your water heater. There is a pressure relief valve on top that may be releasing water because your primary water pressure reduction valve for the house is worn out. The fact that the leak is intermittent suggests this.
Check Water Heater's Plumbing. The problem could also be coming from an overhead or nearby plumbing connection. If you can locate the leak try and tighten the pipe fitting until it is snug.A leaky water heater could also be caused by a leak of the temperature pressure relief valve, or T and P valve.
