Expansion tanks can be installed anywhere on your homes plumbing systems; it is not necessary to be installed close to the water heater. We recommend installing the expansion tank on the cold line, downstream of the shutoff valve.
Expansion tanks – though recommended by retail stores to be hung in the vertical position – can be installed at any altitude. Retail expansion tanks come with a Saddle Fitting, a device that clamps around the pipe with female threads that will accept the expansion tank.
