I am preparing to install a salt water generator. I was told by my pool man that I cannot install a SWG with copper plumbing. All of my above ground plumbing is copper but below ground is PVC. I can dig down and change it all to PVC, but I would like to know if SWG systems should not be installed with copper plumbing in the system. I was also told that my stainless steel filter was a no no also. I Have purchased a new hayward "plastic" filter, so no problem there. I asked about the heater and they said that it was a "soft" copper so it would be okay.

Any advise or opinions?

Thanks,

Ken
