My pressure sensor broke last year in FL& I came home & I had water coming out of my pump. I took it apart & found the part broken. I talked to Shur Flo & they sent me a whole new bottom of the pump with a new sensor. They wanted me to send the pump in but I talked them into sending me the new part. It's worked good so far.I was glad my pump was in an outside bay. Nothing got wet in side.

Sounds like the pressure sensor in the unit is faulty. I don't know if there's a field repair possible -- but ShurFlo will probably replace the pump under warranty.

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?
