I went to the hardware store for furnace filters today and grabbed a few PVC fittings just for grins. I was bummed that the 1/2" fittings I got had an inside diameter of 17/32". Going to do some checking at other stores to see what I can come up with.
Do you have a lowes store near you if so I can look up the stock number for you the next time I pick some up.
Will check to see what Lowes has in the next couple days. If they don't have anything I'll try the plumbing supply place! Thanks.
