We have our pool up, and are currently running the pump with an extension cord. The man who helped us install the pool told us just to use the extension cord, but we thought running electrical to the pool would be better long term. We've had some unexpected/no fun house expenses this winter though, and I really don't want to spend $750 for an electrician to run wiring (that is the 1st bid we got). Is it safe to use the extension cord for awhile while I save for an electrician? Thank you so much. This board has been very helpful.
