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.

Any ideas?

Your house was built at a time when galvanised pipe was common, the problem is most possibly your pipe has slowly corroded closed in 1 or more places, thus when you turn the hot off the pipe charges open and you loose pressure the longer it is on with a new water heater and old house that is what I would look at a switch over to Plastic with some of the new shark bites is not really that hard and you may get all the pressure you have on your cold by just replacing the main line worth a look and cheaper than another water heator that may end up with the same problem
