Tank-type water heater death!

I started out my day with a visit with a friend of mine who is helping me make the cabinet for my bathroom. During the cutting process; I was called to an emergency. My in-laws 20 year old tank-type water heater gave up the ghost today. I stopped by to see if it could be fixed; but after seeing the water leak all over the ground at an astounding rate I new it was over. So off to the supply house we went and got all the rest of the supplies to install there tank-less hot water heater. And roughly seven hours later they had a new tank-less water heater installed and running! On the bright side; I got another job on the huge list done.
