Hello. I recently had my patio redone. I now have stamped concrete. I am considering installing the brass anchors and safety cover myself and avoiding the $500+ charge from the pool company to do it. I have seen the videos and read instructions. Most of the videos show the cover somewhat laying on top of the water while sitting over the pool. They then say measure 20" from cover edge out for placement of brass anchor. My question is, doesn't the cover need to be fully flat/stretched and supported over the pool for the measure.? The loop-loc instruction says lay ropes across pool to support the cover. All other videos show the cover just laying on top. I can't imagine the pool companies securing long ropes to support the cover during install? Any ideas, suggestions, comments from anyone who installed their own cover. My cover is a Merlin ... about 4 years old. I have purchased 35 Loop-Loc brass anchors for the install. Appreciate any info.
