[QUOTE="hoff135, post: 8059114, member: 33"] In the process of setting up a shurflo pump to pump water to troughs. I bought the pump with a little accumulator then realised I could have something much bigger to save the pump from cycling so often. So I bough a 60l one. Been testing it today but what I'm finding is the pump stutters to a stop rather than a clean cut out at the desired pressure. I think over time this could wreck the pressure switch as it probably arching across. I think the problem is the accumulator is so big it approaches cut off pressure so slowly that it doesn't switch off clean. When I tested with the small accumulator it cut out properly. I though I could play about with the pressure of the small accumulator to make it work but it's not. Currently pump kicks in at about 25psi and goes up to about 36 and cuts out. The system stores about a bucket full of water which is ideal. I have set the big accumulator at about 24psi which according to YouTube videos is about where it should be, just below the cut in for the pump. Only thing I can thing of is to fit a different pressure swith in line on the pipe and bypass the shurflo on. Any help appreciated [ATTACH type="full" alt="20220326_161830.jpg"]1025098[/ATTACH] [/QUOTE]
