Hi, I'm new here and I'm installing my own Inground shotcrete pool. I have a question about equipment start up and flushing. What is the process for flushing out the pipes. I know there will be some dirt in the and PVC shavings in the pipes at initial start up. Is it ok to run this through the pump into the filter. My plaster guy said I should flush pre plaster. How would I do that?
