There's an access point to a drain for a buried water line running to our garden. The housing for this access is busted and I'd like to replace it, preferably something with a lid. This was probably put in several decades ago. I think it might be a piece of clay flue, but I'm not sure. The outer dimensions are 13"x18"x23" and the wall is about 1.25". Can someone confirm from the pics if this is clay flue? Is there something that works better for this type of installation?
Thanks
Keith
