We were checking over our pool (just installed July 2013) to get ready for opening and discovered a large crack in our Pentair Admiral S15 skimmer. There was no water in the skimmer or tubes. So, I assume it was just defective.
The pool company is going to send us a new skimmer but told us that installing the skimmer is "easy" and that we can do it ourselves. I looked on the web and found some warnings about not letting the liner pull itself down from the opening while installing the new skimmer. So, before we get ourselves in trouble, I was wondering if anybody had any tips for this that they could share.
Also, any thoughts on why the skimmer would crack like this after only 3 months of use? We're in upstate NY and it was a nasty winter, but I would expect this thing would be built to withstand the cold. Is there something else we could have done (other than draining it) to prevent this from happening?
