Two months ago I change out both my heating elements. To find that there was a lot of calcum build-up. So I drained the tank and shop vac as much of it out that I could. When filling the tank back up I did not open the hot water valve too one of the sinks. Well when the water level got up to the top element it began to leak. So I easied back on the element and POW!!! Water everywhere.. After cleaning my short out I quickly theared the element back.and opened one of the vavles. Now the water in the rest of the house comes out very slow. What can I do????
