Also, Rex, is the outlet end a T to create turbulence? Otherwise, wouldn't a regular elbow work just as well?
I use a T so I can use a flat plug so it sits level. I would guess it also creates a bit more turbulence.
If you need 5/8" barbed fittings contact me soonest. I will be headed out to a store today that in the past has always carried a good supply of 5/8" fittings. Do you want straight or elbows? What size thread do you want?
Let me know.
