Mounting an expansion tank

I have a new Jayco Eagle Premier 321 RLTS. I want to install an expansion tank in the water system But there is no room or very little room In the pump area. I have read that you can install it anywhere in the line after the pump. Does it have to be installed in a cold water line or would either line work?

Technically anywhere in the system will work. However, to ensure the pump does not cycle it would be best to have it installed somewhere after the pump and before the first Tee.

The accumulation (aka expansion) tank is a small pressurized tank that usually is about half full of water and the other half has a pressurize bladder. The idea is to have a small reservoir that does two things, one as the pump pumps it keeps you from seeing little surges in the water flow, secondly if you have heard your pump cycling on/off repeatedly, as in a faucet is cracked open or you have flushed the toilet, it helps keep your pump from turning on all the time. This is great at night, as you may get one or two bathroom runs during the night before the pump turns on, waking up the light sleepers.
