Test and Adjust Water Pump Bypass Valve with Unit Removed
Ok, I am replacing my current pump because it is apparently allowing water to flow back into the tank causing it to cycle and there is no longer rebuild kits sold. The replacement I bought is the Shurflo 4048.
Yesterday I had someone come out and install it(The pump is in a really difficult place to get to). It pumped water great but never shut off. He pulled, tested it, and claimed it defective. So he then put my old pump back in until I got another replacement. So today I call shurflo to go about returning it and they recommend adjusting the bypass up. I just tried to call the tech to see if he tried that when "testing" but haven't heard back yet. However, my guess is no.
If it was still installed all it would take is a quick turn on a hex screw to test it out. However, since it's been removed I need to setup some kind of rig to get water and power to it. I'm think I'll need a bucket with some water in it, a hose for the inlet side, another hose with a shutoff valve for the outlet, and someway of getting power to it. I figure some alligator clips and then I guess I'll need some wire, and I have some of those twist on splice deals that I can use to join all that together. Then i assume it would just be a matter of running some water through it, then shutting the valve on the outlet side, and the adjusting the bypass up to see if it shuts off.
Am I forgetting anything? Any tips? Anyone have any idea how much one turn adjusts the pressure up? I'm going to have to go and buy all this stuff but since my old pump still moves water I was going to set it up to pump water from an external tank into the onboard tanks and I'd need all the same stuff anyways I think. It's gotta be worth a shot because if that's the problem I fully expect the tech to eat the cost to put it back in, along with the cost to put the old pump back in.
Thanks for the help,
