My house and electric water heater is about 16 yrs old. The house has been empty off and on most of that time. The house was rented last May and all of the water pressure was fine. I moved back in last September and have had this problem from the beginning. The only water pressure problem is with the hot water. All points of use, kitchen, 2 baths, and washer have the same problem. The flow of hot water is not as big as a straw. The cold water is fine. Does anyone have any ideas???
