Great item and fast shipping.
I purchased this for a sewage ejector package I replaced in my basement. It' works well and its operation is very quiet. Also, I was impressed with the one day delivery

Excellent product...will buy again if required
Similar to in-line check valve previously installed. Thought I'd replace it when I installed new pump, alarm and controls. They only last so long and then they start leaking. Easy install and work great.

Well made, works as intended
This is a sturdier version of what you might find in a big-box store.

Just what I needed
This Zoeller In-Line Check Valve is just what I wanted. I am integrating a new battery back-up sump pump into a 70 year old commercial system that was piped with galvanized steel pipe and bronze valves and formerly used two (2) tandem pumps. Over the years, one of the pumps was removed and the other was replaced with a more modern design. All of those high quality old valves are staying from the removed pump, but from the floor down into the pit, they'll be PVC plastic. Only this valve mounted horizontally and an elbow will be above the sump cover. The "splice" will be easy. I just cut off the threads on a galvanized nipple and screwed it into the old bronze gate valve. Then, I slid this valve's sleeve onto it and tightened the clamp. The other end slips on the male end of a "Street-Ell" and is similarly fastened. The Flapper-Style of the valve also has minimum resistance, so the battery powered sump pump doesn't have difficulty overcoming back-pressure. Job done, it looks good. and works good too.

Awesone Part and Supply Houses Delivered as Pitched
This part replaced a poorly installed check valve that was leaking after 1st uses.
The best trait about this assembly in my opinion is the robust coupling hoses.
Much better than the ones found in big box stores,.
