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.

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.

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.

I purchased this check valve because I was skeptical of the cheaper flapper-style ones. Replacing plumbing is not something that I enjoy doing, so I wanted to get a quality valve that would last. This valve works exactly as it's designed to and is very easy to disassemble and clean. One thing to think about though is the pump that you plan on using with this valve. I have a Tunze Silence 1073.05 that is variable speed and I found that I needed to have it nearly cranked to the max to provide enough pressure to raise the valve. This is fine because I run my return pump wide open anyway, but if you have a less powerful pump, you might find that it isn't powerful enough to open the valve. Overall, a great product worth the price and I would certainly recommend it if you're looking for a check valve.

i have .75" flexible tubing in my sump, and figured this would fit. The slip ends themselves are actually 1" and 1/16" inches, my .75" tubing wont fit. The valve: Inner diameter is .75", outer slip fit diameter 1.0625 (1" and 1/16"), end to end is 6.25" and at the widest part it is 3.375" (3" and 3/8"). Great looking valve, great build quality, I hope my review saves some people an unexpected trip to the plumbing store.
Quality is worth the price By Thomas on 3/13/2012

My initial return had a swing check valve. when the pump turned off a huge water hammer developed that would take several minutes to resolve. I replaced the swing check with this valve and no more water hammers. The design and quality is so much better than a swing check.

I had to many problems with my water siphoning back into my sump, so i looked into there check valve and even tho it was pricey well worth every penny! very heavy duty also.
pricey but very nice By Craig on 8/19/2011

This is an extremely solidly built part. The walls are strong. The cap is beefy, seals well, and is easy to remove. The weighted stopper is easy to remove with just your fingers. (While clean anyway, haven't had it long enough to say how easy it is to remove when dirty.)
It IS definitely rather expensive, but I was willing to pay it for the extra piece of mind. I've had trouble with siphon break holes stopping up with salt creep to not have one of these.
