I had a ShurFlo failure so I purchased a new pump and installed it. However, now when the pump turns on, it shoots water out of inlet for city water. It works fine in the house but it seems like I have a check valve issue.

Can anyone tell me what I did wrong?

Nathan, I guess you have the inlet and output in the correct direction. Is it possible you have the electrical 12 volt DC in the reverse polarity? That would cause the motor to run in the wrong direction.

Nathan if you look at the check valve with the water shut off you will see a pin and spring in hole for hose connection. You may have to reseat the washer ring inside of spring and clean any sand or debris that maybe caught in ring allowing the water to shot out hose connection.

The two wires were clearly Black and Red so i would assume I have it wired as the last one was. I did pause on the lines thinking I might have swapped them. The inlet is coming from the 'T' where the winterizing feed is. The outlet is going to a 'T' mounted behind the panel near the outdoor shower.

Do you know where the check valve would be?

You will have a screen in the hose connection that I did not mention remove it and you will see the pin and spring that acts as check valve so water will not be pumped out at you.

That was the issue. It is still dripping slowly but much better than it was. I need to get that part and replace it I guess.
