I'm wandering if any one can help....
my flow jet 95 psi was leaking, so i ve got a new one exactly the same,

all i use is tricoflex with a control valve on the end ,any ways when using the new one unless i have max flow(or near as dam) the pump stops and starts, this never happened with my old one.
also noticed the pumps quite warm, didn't notice this with my old one..

help much appreciated
