60 year old house recently completely remodeled. Water heater located in small closet in finished basement…10 feet away in another small closet the water lines enter and leave going through a water filter and an attached water heater expansion tank in the process…I’ve never seen an expansion tank before that was not located at the heater…Is this permissible? photos below
FACTS TO CONSIDER ABOUT THE LOCATION
The location selected should be indoors in an area not subject
The items which should be installed in sequence in the cold
water line are (1) the EXPANSION TANK must be installed
at least 18 inches away from the cold water inlet fitting on
the water heater, (2) the PRESSURE GAUGE, and (3) the
PRESSURE REDUCING VALVE, if required, see Figure 1.
The expansion tank is designed to be supported by the system
piping in the vertical position.
The expansion tank, pipes and your connections may, in time
leak. Put the expansion tank in a place where a water leak will
not damage anything. The expansion tank should be located
in an area where water leakage from the tank or connections
will not result in damage to the area around the expansion tank
or to the lower floors of the structure.
Check Model and Manufactures Instructions as the one above, it could vary.
