Hot Water Crisis: Low water pressure and spotty heat

[Daniel Pitner]

The house that my wife and I currently live in will be a short term rental within the next few months, however we have one big issue: I can't solve our hot water crisis!

About 6 months ago our water heater worked very well and had regular water pressure.  I had to change the elements, however, about 5 months ago which is where are of our problems have begun.  Since I changed the elements I now have very weak hot water pressure through the whole house. I'm also getting very hot water to every faucet in the house EXCEPT for both of our bathtubs. I can't figure it out... any ideas you have would be tremendously appreciated!
