Well, the 05 pump is shot, so no amount of revised controls will make it work. Either the valving is too worn or the motor, even tho it runs, won't put out enough rpm's. No-load the 05 pump draws...

Don- Most failed units go back to ShurFlo thru the trade-in, as the 3 year from born-on date warranty covers the vast majority of failures. If not for the 3 yr warranty, this pump would have been...

IIWMI'd carry a spare pump. Seems the electronics in the 5.7 either last a long time, or die fairly early. I put in a new 5.7 in March & its failing now; Smiths put their new one in Feb and the new...

I had the a surging issue since replacing my OEM pump about a year ago, or maybe more accurately a delay. I'd open a faucet and the pressure would drain out of the lines to a trickle, then the pump...

Jim- the OEM wiring is a 3-way switch direct to the pump, no relay. If you have a relay, latching or regular, it was added later. If you have one, it is probably either in close proximity to the...
