Check valve failing

[Akrio]

Looking for suggestions for a 1" check valve for my home. I'm on town water, the house was built a few years ago and there was a Watts 3/4" LF7R dual check valve installed. Since moving in for more pressure I've added a CSV and Goulds J15S. I've had two check valves fail since then, don't know if it's related to the pump setup or not, curious if can add any stress to the check valve. When the 3/4" LF7R failed since my sprinkler zones can run as high as ~15gpm I decided to replace it with the 1" LF7R that supported higher flow and that failed as well.

Are there other dual check valve options that are more durable?

• Easily replaceable engineered plastic check modules

Anything that has "easily replaceable parts" is no good. Sorry for your problem. But I would use just a regular 1" brass spring loaded poppet style check valve. Here is just one of many.

Yeah the plastic flaps in there were not confidence inspiring. The two times I've pulled it apart one is loose flapping around inside and the second flap is missing entirely. I'll have to check with my local code but is there a reason a dual check valve was used? The Merrill appears to be a single check. I think that's fine personally but wondering if they had a reason to set the house up with a dual.

Dual is supposed to be redundant and safer. Lol! Not safer if it doesn't work at all. If a "double check" is required for code, Just put in two good ones in series.

Thank you!!
