I've had this about a year. Have to keep it clean in order for it to work. the piston valve gets stuck in the open position about 4 months after a cleaning.

I thought it was overpriced when ordering but was impressed to see how solid and well built it was. Works well and easy to maintain. Well worth the money for the peace of mind.
Failed to Perfom By Christopher on 2/3/14

This check valve failed to perform during a power outage. I use it to stop the water from back-flowing from my display tank into my sump. The power went out one night and the check valve failed to close (this was within two weeks of purchase so it was still new/clean). This worked when I turned the power off to the pump, but failed in a real world power outage. I wish I could get my 50 dollars back, this was a complete waste of money and could have been a disaster if my sump wasn't big enough to contain all the back-flow.

The check valve is working as intended and feels like it was made strong and to last. I highly recommend to anyone with an in sump skimmer or anyone with a small sump. Enjoy!!

I was skeptical when setting up my first sump but after buying this, I don't worry about my sump overflowing. Very heavy duty build. Haven't had an issue with it. It's a bit pricey but the peace of mind it provides makes it worth every penny.

Its great how you can take these completely apart and clean them. I guess you get what you pay for.

After purchasing this item i felt that i spent too much money on a check valve. When i received it and installing it I was more then pleased with my purchase. I could easily clean it unlike my old flapper check valves i have on my older tanks. I will soon purchase more to replace the older ones.
Very Nice By MICHAELO on 9/30/13

This is a well built back flow check valve. A little pricey, but considering what it will help you not have (i.e flood) it pays for itself. If you want a guaranteed check valve that you can physically take out ,clean and inspect. This ones for you!

It’s the best check valve on the market. I switched from a different brand. George Fisher check valve is more expensive but worth it.
Good materials, but does not reliable By Kevin on 7/6/12

I was very impressed with this check valve out of the box, but it fails to close 1 out of 10 times during my feed cycle. I have two of these plumbed into two different returns, and both exhibit the same behavior. The units have been used for less than 3-4 weeks, so they are not dirty. I am disappointed in the performance given the high cost.
