I just ordered an exotic marine overflow with 1" bulkheads. Does this mean I need 1"pvc? I wanted color pvc so I was trying to order so I can drill and plumb same day
Generally yes. Call the place you ordered it from and they should be able to tell you.
I presume that if that's normally the case then this one will be the same. Just not familiar with plumbing. I have spent past 5 hrs researching pvc pip and almost have it all in a cart to order. Getting closer.
