Have not run pump or filter yet. Have been slowly removing mud silt from bottom using screen net. Noticed filter is leaking at filter drain and at waste hose. As we have removed most mud now, leak seems greater. Capped filter drain and folded waste hose and now see water drain by pump. Filter has 10psi reading and multiport valve is at "winter" position. Assuming that removal of mud over pool floor drain is causing this, should we start up pump in recirculate mode? First time pool owner. Vinyl 20 x 40, Hayward S244T filter, Pentair Challenger pump 1hp. Was told pool not used in 4-5 years when we bought house in Nov 2011 and told liner was about 10rys old. Thanks for any help - Tex.
