Pretty sure I've seen it at both stores. You probably called and got some idiot on the phone (doesn't know wtf you're talking about, "no, we don't have that").
Got the 1" ID braided tubing and it happened to be the same size as the regular pvc pipe. Got plumbing done.
But brand new seaside aquatics sump got a leak. F ME! Shout out to David [MENTION=4363]blkg35[/MENTION] for coming through with the Weldon since every store was closed on a Sunday night. And his dad for the patching tips. Worked like a charm. Knock on wood.
