In fact two questions.

I want to use Hunter MP Rotators mounted on MRP40 pop up bodies. The MRP resticts pressure to 40 psi, however the pressure from my pumped system through 1.5 inch pipe is 86 psi - is the MRP40 able to deal with incoming pressure of 86 psi?

From the main 1.5 inch pumped line I need to run lateral pipe of up to 26 feet to each individual MP Rotators, what diameter pipe would be best - would 0.5 inch be OK?

Have emailed these questions to Hunter but no reply!

Many thanks

Andy
