tide check valves

[CheckMate]

Is there any other manufacturers that produce a product like the RedValve TideFlex check valve unit. I am looking for an 8" unit and I would like to compare product and price.

The unit will be used on a potable water reservoir overflow pipe. It is more of a security unit and to keep critters out of the line.

I have used Tideflex all over the world and I have never been able to find another supplier, although Dunlop did try I think but stopped some time ago.
