I've been working on getting the dry plumbing completed while paint dries and was making great progress until I opened the AGA Overflow kits... the bulkheads are hose-barbed and not slip.
*sigh*.. The LFS will not swap the bulkheads

and I will not pay another $40 for the correct type; so, I am taking the kits back to the LFS and will build my own durso stand pipes.
