Makes sense. The addition prep inhibits the ground heaving when it freezes... Northern Canada wow! short swimming season I imagine;-) Here in Indiana it's about 4 months... Bill_H

Hi Chris, Maybe it is just assumed, but you most definitely want to include a GFI (ground fault interrupter) in the circuit. It can be installed at the outlet or at the fuse box. Most places it is a code requirement anyway. Bill_H

Thanks Trigger, That is my thinking exactly. I have contacted Zenith and waiting response. I did talk to another dealer of Zenith pools and they confirmed a minimum of an 8"X16"X1" patio block is required for each post. I will likely be taking it to small claims court. The contractor told me he would testify on my behalf... Bill_H

I've been looking at pool installation manuals and your description has never been mentioned. It's interesting they are asking you to put the dirt around the pool. I would think this is part of their installation... The original installer of my pool was a member of the APSP. Does anyone know if they have installation guidelines for above ground pools? Thanks, Bill_H

Recently my 30' Zenith pool failed when the liner breached. It was four years old. The installer that I contracted to replace the liner discovered there were no supporting blocks under any of the pillars. Some of the posts had sunk and caused a metal panel to come out of the groove which caused the failure. My question is whether that is considered good workmanship. The pool was installed by a APSP certified professional. Thanks for your opinions. Bill H
