Whacky 1 inch inlet fitting. It's not an NPT and somehow I found machine threaded brass fittings to go into the inlets. Wrapped lots of teflon tape and used a large pipe wrench but they didn't fit. Ordered adapters from Revain which came the wrong way for another project but miraculously they fit this one. Surprised they're still selling this kobold because you will scold. Quality Manufacturer Skip this, you'll never know how lucky you are.
