How to drain (flush) a hot water tank and redo PEX pipes and fittings

In this video we will look at how to drain (flush) a hot water tank. We currently have two 50 gallons gas hot water tanks connected in series. We will drain and disconnect them in order to have two stand alone hot water tanks.
One hot water tank is going to be used to heat our radiant floors in the basements. The other hot water tank is going to be used as the main hot water source for our home.
In this video we also go over PEX piping, PEX fittings and PEX valves.
