30-0151 UniCheck 2″ Cast Iron Check Valve – Full Flow Backflow Preventer for Sewage, Effluent & Sump Pump Discharge Lines – Durable Cast Iron with Neoprene Gasket & Stainless Steel Hardware

Excellent Zoeller product. Cast iron construction is solid and much quieter than the plastic one it replaced.

Bought this again after the original one failed after about a decade of use. The cast iron makes a difference in comparison to plastic and noise levels. Really easy to instal, fit and functionality was perfect. The rubber slip on boots fit tightly and seal good with the stainless clamps.

Came complete with all SS hardware

I moved into a very old Mid Century home about a year ago. The first thing I noticed was a bad odor coming from the basement. Being a city dweller I had never had to deal with an ejector pump. I did some research and found that my old sump pump was defective. So I did more research and found that Zoeller made some of the best and found almost all reviews to positive. I replaced the Backflow preventer as well as the Ejector pump. The old was loud, every time it eliminated waste up into the main it sounded like an explosion. My cats even jumped. (I think they still have PTSD from that pump) So long story short, the new Zoeller backflow preventer and ejector pump are very quiet, efficient and sturdy. They're made off Cast Iron and are heavy duty. I think that's what makes them so quiet, instead of those cheap pumps. Believe me, you want to pay a little extra and use Zoeller. PS- I'm considering getting Aroma Therapy for the Kitties.. Lets hope they'll forgive me.

Let me start by saying I am not a plumber by trade. However I’m broke and can’t afford one so I must do my own repair work. A while back our sewer extraction pump was overflowing and leaking and the previous owner even had it venting inside the house. So I fixed the pipes to vent outside, replaced the cover and bought 2 separate check valves and they both leaked. So after some research it seemed to be the consensus of the plumber community that this brand is what you want. I was reluctant considering it’s more than twice the cost of others but I bought it and I’m so glad I did. Not only did it not leak from what I read if in the future it goes out you can rebuild it because it’s cast iron not plastic. If you are trying to send poop uphill just buy this one first or you will have to buy it after you fail with the cheap ones. Quality comes at a price but so does piece of mind. After all I want what is best for my family and this is it.

There was a specific reason I chose this product. In the first place, I needed a strong check valve to keep waste water out of my basement when it flooded and forced the water back into my basement. This product looked healthy enough to do that. Secondly, I needed a valve that was easy to install and functioned as advertised. So far so good. I don't need another flood to prove out its quality.

Great reliable check valve at a reasonable price.

There are hair raising stories by people whose plastic valve exploded, because it was...glued. Even drinking bottles are made as one piece by blow molding...what an idiotic design for a part under the internal pressure! I just replaced it with Zoeller valve because I DID imagine my basement looks when that valve breaks and starts shooting excrements all over the area.... GOOD job, Zoeller...your valve is top of the line and worth every penny!

merci

very fast delivery, had to cut 3/4" from the sump pipe but installation only took about 15 min. altogether and no more loud thud after every cycle

This was very easy to install and works well. I installed it replacing a leaky one. It is being used for an ejector pump in our basement washroom.

Very robust unit. It should last for many years.
