No. Depending on your model and the whim of the guy
who plumbed it at the factory, you might have 1, 2 or
3 valves in the bypass area. (This is the rear of the
water heater)
One of these valves is between the hot water heater inlet
and outlet lines. It connects the inlet with the outlet.
In order to bypass the water heater you open that valve
and close the other valve(s).
This allows you to pump antifreeze throughout the system
without pumping it into the water heater because it's
been "bypassed".
There is either a hose already on your pump with cap
or valve on it OR you have to add your own. This
extra hose is used to suck antifreeze right out of the jug
and pump it into your system during "winterization".
The length of water tube that runs from the city water
inlet to the T near the pump is not involved and IMO really
needs to be blown out or drained in some way to protect
it. I have been known to do this "blowing" with my
mouth
(Insert joke about me being a big blowhard here......)
As Bama said, a photo of the rear area of your water
heater would help us give you specific instructions.
Good Luck!
