Setup: Electric 53 Gallon Heater, installed in 2014 by previous owners. Location: Tampa bay, Florida, Home built in 1961, typical cinder block house.
WE purchase the home in December and all has been working great.
Issue: Very low hot water pressure in the entire house. Water begins when first turned on with an acceptable amount of pressure but quickly over a few minutes drops to very low pressure. Enough time for a 5 minute shower, if that!
We called a plumber out and they recommended to replace the water heater. They suggested there is probably a clogged line in the water heater itself?
What I have done: I have drained the hot water heater from the bottom of the tank for about 5 gallons, there was no sediment what so ever at the bottom.
