Are there any special precautions or procedures for removing
the expansion tank that is on the cold water inlet to the
hot water heater?
I need to remove mine so I can TEE into the incoming cold water
line (to run a new pipe to the shower), but don't want have hot
water spewing all over the place as
soon as I loosen it. Is there a way to relieve the pressure in
it first, or should I open the breaker for the hot water heater
and let it all cool down first?
Also, what's the proper way for this tank to be attached to the
cold water inlet line? It looks like the guy who put it in just
drilled a hole in the steel inlet pipe wall and used a rubber
gasket and clamp to attach the expansion tank to the pipe. Is
it more appropriate to install a TEE connector and a threaded
pipe to the expansion tank?
Thanks in advance for any advice.
