Pump Not Turning Completely Off

[NuthatchBC]

Our pump must be one of the older ones because it has only one adjustment screw that just regulates the shut-off threshold.

I spoke with Reace yesterday and he said to play with that adjustment and see what happens. Well, backing it off counter-clockwise caused the pump to run continuously if the faucet was on or off. I tried to turn it clockwise but found it was already turned all the way in i.e. there was no more adjustment possible. Reace said they do this at ETI. So, diagnosis is a bad pressure switch. Reace is sending up a replacement pump. Apparently, the new one will require adjustment by me once installed because it has some sort of internal bypass that the current one doesn't have.

I apparently am the first one, according to SHURflo, to have a pressure switch fail. Go figure.

You may have used up all you're bad luck and get lucky with the new pump. You may get one that was setup properly at the factory. We can always hope!

My Artis pump also failed after 2 yrs. on my 2012 5.0. It would take a long time to shut off while making a low muffled sound then finally gave up the ghost 2 weeks after the warranty ran out.
Replaced with a Sureflow and it works much better than the old Artis.
