Pump is D.O.A as of this AM. Lived a long and productive life but dead now. I'm up the creek. How long do I have before problems begin? Do I buy online and wait for 2-4 day's or pay the local pool store $100 more just for time sake? Our temps are only mid 70's for the next few days and I'm hoping my pool will survive without turning green. TIA for any help!
