Overall very impressed with this pump! I just got it today and everything lined up to the old liberty 403 pump I had prior to this making the hook up very simple. Pump is nice and quiet compared to my old one. I’m hoping it will last as long!

Nice pump, quiet operation and the best feature is no water hammer sound when it turns off. It does include an integrated back flow valve, how ever I installed an external one anyway.

I purchased this pump to replace a dead older laundry pump. This thing is super solid and easy to install if you have minimal plumbing skills, very recommended.

Worked well for just over 1 year before the pump failed. It took 5 days (emailing and calling) for anyone to reply back to my warranty request. Stated that they would replace under warranty but it would take “several weeks” before I could expect a replacement, and there was no other way to get a replacement. Unfortunately, I can’t wait “several weeks” to do my laundry so I will need to go out and purchase a replacement. I would avoid buying this item due to its short life span and lack of appropriate manufacturer support.

Well build! Three 1.5" threaded ports. Two input and 1 output. There is a input port on top and one on the side. (Or the side for in and the top for vent) I do not have a sink. So I capped the side port and stubbed a 3 foot 1.5" piece up from the top port, and hung the S-hose on it. It is working flawlessly! I shopped around and am glad I landed on this unit!

An error in the installation manual drawings indicates that the ports on the top of the lid can be used interchangeably for waste or vent. This is false. One of the ports is smaller on the interior side of the lid to fit close with the outlet pipe from the pump. If the other port is used for waste, much of the pumped water will circulate around the larger opening back into the basin and not develop enough pressure to discharge. I falsely assumed that the manual was correct and installed the waste on the wrong port, requiring disassembly to reorient the pump and do more PVC work to cross the vent and waste.Make sure the vent port is connected to your actual DWV venting system. Trying to shortcut with AAV or island vents will pressure lock the system and cause malfunction.

The sump was leaking for the top in the location of the screws on top...I noticed that none of the screw were tightened down...I tightened the screws and I'll see if it continues to leak.The pumps works great but at first it didn't turn on until I shook it...after that it seems to be working great except for the leak which I think should be okay.
