The Reeflo Blowhole comes with half of a threaded 1" union fitting already installed on the input and output of the pump body. To reduce input suction and output pressure I'd like to plumb it with 1-1/2" PVC, so I'd like to find a 1" male thread x 1-1/2" socket fitting. It exists, as a 436-133 from Spears, but it's an uncommonly used one, so Lowes/HD don't carry it. Online places I've found like pexsupply.com and flexpvc.com carry it, but it's about $10 shipping.
Are there any good local fitting stores? I am going to call the Gaithersburg pool supply place that I got my Flex PVC from on the off chance that they'd have it because I know some pool supply places carry stuff that isn't commonly used for plumbing.
Thanks.
