Zoeller is the big name in sewage pumps, and this is a very good price for this common model for household lift stations. I install a lot of these, and this is the best price that I have found.
This is a high quality pump that is heavy duty. It was recommended by a relative who is a master plumber. I don't think we'll need another one for many many years.
The system works amazing using 3" pvc and hose clamps to the septic box. I fiberglen inserted my 2" pvc pipe in the hole, poured some concrete mix around and buried. This pump is heavy duty and easily empties the septic box less then 30 seconds. Couldn't be more happeir with the products and the shipping and Amazon.

On time, was advertised like new. It came in the box with owners manual, looked like it was brand new.
I really like the pump! It's very strong and does it's job well. I've had it installed for six months and had no problems. I had never installed any type of pump before and this was very easy to install. My toddler helped :). I used the silent check valve that's sold on Amazon. That really helps the noise. I have a toilet, shower, and sink in my basement that use this pump.
I needed to replace the builder's injector pump in my basement and have always used Zoeller pumps as they are reliable and the switch with the float is so much better than a tethered type switch. Zoeller is worth the money and this was a great deal.
I installed it in basement last month and it works as expected. It seems sensitive to the water level and the noise is acceptable.The only concern I have now is that the top part became yellowish after one month. I am not sure whether it is rusting or it is a &#34;natural&#34; color change.
I bought 2 of these pumps a (one already installed & the other as a backup) a while ago. A durable pump that is up to the task each time it's called upon. It has not disappointed me yet. I have always relied on Zoeller's trusted performance and reliability. I highly recommend this pump.
Bought this pump not knowing which to get. We placed a travel trailer on our acre lot for a rassed the pvc pipe in the tote box. The pump is so quiet even with the lid open. Also I had to pump upgrade some 60' to the top of my house septic tank ( about 4 feet higher ) where I drilled a few holes in a circle verily easy and knocked in the concrete thelative to stay for a period of time. I bought a heavy duty storage tote for a mini septic.
