I am trying to pry up the nails that is holding the flange down. got 2 more that is difficult to pull up. the pipe is pvc. is there anything that I should know or watch out for???

can anyone help me proceed with steps on completing this project, or should I call a plumber? Just to let you know, a friend of mind would complete this job for $150.00. is this a rip off???

couldn't you get a spanner under it?

with friends like that who needs enemies.
