I've learned a ton reading through pool school and various threads over this past weekend.
The pool I'm inheriting with the home we're purchasing needs a new pump and filter (...as in the current pump will not power on). I'm confident in my ability to plumb the pvc up as I've worked with pvc fittings many many times in the past. What I cannot figure out is how to plug up the pool in order to disconnect the current pump and install the new one. There is no valve on the current set-up (I'll be adding one during this process) and the pool is full of water.
