Simpure doesn't offer any support. Brass inserts on in/out flow ports are not done to spec. They allow only about 1/4" thread engagement, where at least 7/16 are required. Trying to contact support on this - phone line goes right into voicemail. Left a message - no call back. Email gets answered in a few days with nonsensical stuff, like make sure you are using NPT thread adapters (dah!)
@@simpurelife after 2 weeks I finally had a call back from engineer from Canada who offered a replacement and promised to send an email - still waiting for it. Instead I bought a 1" npt tap and re-tapped threads. The filter is installed now and working fine - no leaks.
