Works 1 Year In
Great pump. Working solid for a year. No issues.

Works as designed. Beware installation manual error
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.

Happy everything went in smoothly
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!

Almost good
The pcv on my pump was a little short Upon delivery it dumped water all over due to pump moving inside. The gasket isorritatimg to reposition when taking it apart . I ended up using a small amount of gasket sealerto hold it in place Other than that it seems ok It only gets used about once a week for the water system regeneration.

Nice Pump
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.

Float sticks
The pump worked well for a day then apparently the float is stuck and it won’t shut off. Had to unplug it

Super easy hook up, works great replaced old manual pump
Ok, so here's the facts. 1. PVC exterior fittings not included just FYI. 2. Check valve inside saves money and time. 3. So quiet you actually don't even here it run. 4. Pretty compact. 5. Customer service is amazing. 6. Works perfectly. 7. I'm not a plumber and I did this myself in less than 2 hours, saved a ton of money.

Used this to replace our old pump in the basement. Works great. Would recommend.

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.

Works great. Exactly what I needed. Fast pump, not too loud. The only thing was the check valve at the pump was broken off during shipping. I would have returned it but needed it right away and got a replacement locally. They should ship this pump with the valve and tube not installed into the pump to prevent this in the future. Solid product overall except the included check valve is this thinnest brittle plastic possible.

I love how everything is self contained and bolted together. Pump is wisper quiet too. The tub offers a few different configurations for pipe routing.
