Do you need to have a chimney liner for gas fireplaces? I have a very large wood burning fireplace, but when I had my house inspected the inspector said that there was not a liner. I am trying to...
"A clay flue liner is a liner for your fireplace. This would be helpful in case you needed to clean your chimney it makes it easier to clean, and less likely to cause fires."
No you can use the pool with old liner. Foxx is strong and the sides will hold without water. The only thing is that you need to keep adding water and eventually the sand on the bottom will wash away.
