So I have been looking around and the hard pipping is awesome. I want to try this but seems that I am having an issue finding the screw on collar like the hoses to the pump and filters. Are these a standard size or is there something I am missing? I was able to make an adapter to go from my skimmer/filter/pump housing to a plunger valve then a hose to the pump, going all pvc is what I really would like to try to do. I have been looking through and cannot find the post that talked about the special adapters. Any help will be appreciated.
