ShurFlo 5.7

[Terry Neal]

Hi Ryan,



What they didn't tell is that they've had a some problems with these
pumps. In all capacities. I am on my 3rd 4.0 model in less than 6
months. All of them start & then stop with no valve shut off.
They just quit. There is an adjustment in the pressure sensitive
switch but they won't tell me how to adjust it. They just say to send
ot back to them for a replacement.



Best of luck with yours.

Terry

Hi folks,







I've got a problem with my relatively new ShurFlo 5.7 water pump.



ShurFlo doesn't know what to tell me, other than to send it back to



them, but before I do I'd like to see if anyone here has experienced



similar behavior.







The pump runs for about 30 seconds, then cuts out for a couple of



seconds as if it's reached it's target pressure despite my faucet



being wide open. Then it runs for 5-10 seconds, cuts out, and repeats



this behavior indefinitely. If I open more faucets, I can hear the



pump boost it's operating speed and it runs slightly longer between



cutting out. After a few minutes of this on & off behavior, the

stops



become more abrupt and I can hear a relay inside the pump flicking off



during each cut.







Anyway, I'm assuming the pump is faulty and will be returning it to



ShurFlo, but I did want to ask here first. I thought these pumps were



supposed to adjust their speed in real time to deliver just the amount



of water needed, not shut down entirely? My intention is to buy a new



one right now and keep this one as a spare after ShurFlo replaces it,



but I'm also concerned of the remote possibility I bought too much



pump for my coach's plumbing system and a new one won't behave any



better. What do you think?
