I previously replaced my water filter with a Shurflo Expansion bottle, but the volume of water dispensed prior to the pump coming on was not very much.
(Basically a 1 or 2 second flush).
I wanted more water before the pump ran so was looking to install a bigger expansion pressure tank. The Water Worker 2 gallon tank looked like the way to go. Water Worker - Water Heater Expansion Tank
I removed the Shurflo Tank by unscrewing the connections I made when I took out the old water filter and the tank came right out.
The new tank plumbing was done with all Sharkbite press on connectors and a section of PEX I keep in the camper.
Total install time was about 1 hour start to finish.
