Torsten is the RoyalExclusiv tech support guy in Germany. Scott is the support guy in USA. I can provide his contact info if anyone wants it.The reply was from Torsten, RE Germany. I have not received anything from the US in ages. Granted I was only asking about intake and outlet sizes and if the RD5 would be a direct fit for a RD3. Not sure if they have a US rep anymore /shrug
I also have a Sicce Syncra SDC 3.0 DC pump which I'm using to run my UV sterilizer. I like it too but looks like it has European (BSP?) threads. It appears to have 1" threaded inlet and outlet, but I was unable to attach standard 1" NPT fittings to it.
