How much heat and pressure do WI parts (tube, fittings) need to be able to withstand? I know the common shurflo pump is rated at 150 psi, but won't the pressure increase since there's a nozzle restricting flow? If so, how much pressure would the pump generate with a 5gph @100psi nozzle?

anyone?

Most shurflo pumps have either a pressure switch that keeps the pump below 150 PSI, or have a bypass switch that some-what regulate the pressure (depending on nozzle size).
