    I’ve been using this for about a year now, and it’s holding up great. It’s a bit loud- I can hear it running in the basement from my living room directly above it. But it doesn’t have to operate for more than 20sec or so to get rid of my washing machine wastewater, so I don’t have a problem with it. But I do have a few complaints surrounding the installation, which is why I knocked it down a star:

    1. As others have mentioned, you’ll need to supply your own external pipes and fittings- there are three pvc screw connections in the unit (one for input, one for output, and one for a vent) and everything else is up to you. My installation took 3 extra trips to Home Depot for various additional components, but someone who knows what they’re doing could probably plan better than me.

    2. You definitely need to add your own check valve outside the pump. DO NOT RELY ON THE INCLUDED INTERNAL ONE. I’m pumping my laundry waste water up about 8 feet to the sewer drain, and every time the pump shut off I could hear the water rushing back down into the pump. It eventually started leaking around the top, until I added a secondary check valve. No problems anymore.

    Bottom line- It works beautifully and seems to be holding up well after using it regularly for a year. But it can be a hassle to get it installed.

    The previous homeowner of my house was using hopes and dreams to push water vertically from the wash machine to the main septic discharge pipe which was over 8’ above the wash machine.

    After some simple PVC piping and an additional check valve it was a fairly easy assembly and install. It only runs when water enters the basin. Solved my issue of water flowing back into the wash machine.

    I’ll eventually add a slop sink in the basement which I’ll tie into this as well.

    Works fine. Installed it in basement, where there is an elevated waste pipe, for my utility sink. Quality seems good. Easy to install. I read previous reviews about not over-tightening threaded male adapters (you need three). I didn’t use teflon tape, putty or anything on the threaded connectors and they are water tight. Hand tight + 1-2 turns with a wrench. Vaya con dios 🤙

    The pump works great and is pretty quite too the capacity is very large , thus the pump doesn’t have to run often but is very efficient

    It’s connected to a small sink in my basement bar area. It was installed about a year ago and this is the 4th time the pump has not turned on gotten stuck and overflowed. The pump gets stock on, never turns off, and sewage water backs up pours out into my cabinet, and onto my laminate flooring. I have a pan udder the pump and a water detection monitor to alert me when it overflows. I wouldn’t recommend it.

    Working great so far as a laundry room lift pump for our basement. A tad bit noisy but no worse than our sump pump. Ours is installed on the floor next to the washer and slop sink and pumps about 8 feet up to connect to another 2 inch drain pipe that leads out of the house. Install was pretty easy and I like that it is completely self contained. Trickiest part of the install was finding a place to run the vent pipe. Once that was figured out for my install (we tied into the vent pipe for our basement sewage ejector). The rest of it was straight forward.

    Product was easy to install (with some basic plumbing skills). I have added a rubber mat under the unit based on other reviews about excessive noise and I find it to be quiet while running. The pipes must be properly strapped and a rubber coupling should be added.

    Works very well, a little loud but takes water out fast

  10. ING RAFAEL ROSAS

    Good product quality, easy to assemble and install but could use a better installation guide for completing the system

    Quite easy to fit using standard ABS pipe from local merchant. Assembles easily. we use it for a basement kitchen sink. I think an external filter would be useful, to stop solid items such as vegetable peelings etc from entering its chamber.

    Works great for a basement washer. The pump is plenty strong and the container is sturdy. The outlet pipe is a little hard to align. You will have to get all the fittings and piping to connect this.

    So if you don’t want to install this 5 times like a cool person then please read. There is a little plastic pin that holds the float in the right place. It is extremely breakable and extremely important. Mine broke while opening and it took me sometime to figure out that it was really needed. If it does break, or is broken, just cut a little piece of wire and install it by bending down both sides. Trust me, you do not want to have to remove the lid after installation so please take your time the first time or this will chew up a few hours.

    I used it for a basement utility sink and it is working great!
