Hi Avast.
I recently replaced the motor on my peristaltic pump. I am not sure why it isn't working properly. It should be simple - if it turns and doesn't have a suction side leak, it should pump. I expected this problem to be a suction side leak, but at this point, it doesn't seem to be fixed by re-doing the connections.
I did confirm the inlet white tubing in the reservoir is free and clear and submerged, with no kinks. I can also easily suck water or blow air through it.
Also, I did get it dripping into my sump last night plugged into an outlet, so I thought it was fixed and plugged it into the sensor outlet. This morning, the green light was on but no water was coming out. That's when I pulled off the outlet tubing at the reservoir as shown in the picture.
I do need this to work, so I will try replacing the jg fitting and I will try re-clamping the black tubing to the peristaltic tubing, but I think the teflon tape should have temporarily solved that. FYI - all the tubing is cut square with a tubing cutter.
For anyone reading this, the system has worked very well for me. I've had a few problems, but they've been self-inflicted, either at installation, or by neglect of the reservoir. Secure tubing attachment at the fittings is key.
I did ask this via email to Avast support. You're very responsive, but seeing as it is the weekend, I'm also using your forum here in case another user might see something obvious. Answer at either location, I'll check back at both.

- It isn't moving water out of my ATO container.
- I can get it to pump water in the kitchen, but slowly - it took an hour to prime a short piece of tubing from a water pitcher. I know it is slow by design, 7GPD, but considering the volume of the tubing I think it should have taken less than 2 minutes. (0.003gal/ft, using <2ft)
- I did replace the pump peristaltic tubing
- I suspect a leak on the suction side, but I have checked and rechecked the fittings. Finally, I just wrapped the whole fitting in teflon tape, which I've used in other situations to troubleshoot vacuum leaks.
- it turns counterclockwise. Don't know if this is related so I'm sharing it, but I don't think it is the problem. The etching on the coverplate has IN on the left and OUT on the right. I think the last motor did this as well, and I just swapped the tubing. For what it is worth, I did check and recheck the wiring. I even swapped the black wire from the power cable. If I put both ends of tubing in the same bucket with the pump not primed, air bubbles slowly come from the tubing on the side labeled "IN"
