I know, I know, so many exp tank threads and here a I am starting another one....
Watts installation procedures say to drain the water heater before installing exp tank; the following from their instructions
4.Shut off power source to the water heater, (electricity, gas, oil
burner switch) and drain system following water heater manufacturer
recommendations.
5. Install the expansion tank in the system (refer to Figure 1).
a. The weight of the expansion tank filled with water is supported
by the system piping. Therefore, it is important that,
where appropriate, the piping has suitable bracing (strapping,
hanger, brackets).
b. The expansion tank may be installed vertically (preferred
method) or horizontally. Caution: The tank must be properly
supported in horizontal applications.
c. This expansion tank, as all expansion tanks, may eventually
leak. Do not install without adequate drainage provisions.
6. Turn on the water supply valve.
7. Open a hot water fixture and allow water flow until all air is removed
from the system.
8. Reapply power to the water heater.
9. Open a hot water fixture to allow a slight flow until the hot water
has reached operating temperature.
10. Recheck system pressure following Step 1.a through c.
is this necessary, or do I just install it and go?????
Thanks alot,
Steve
