Hunter HCV Check Valves

An economical water-saver that eliminates low head drainage for sprinklers located on slopes
If you have ever been faced with a job site that features extremes in elevation, then you have first-hand knowledge about low head drainage. Unfortunately, a system that requires ups and downs to fit the landscape will find that the water in its pipes seeks out the low points when the system is at rest. That typically results in messy puddling at the heads located at the lowest elevation and, ultimately, wasted water on walkways. With the Hunter HCV, this will never be a problem again. Easily adjust to the proper check height and insert this remarkable product in between the riser and sprinkler head. If you've ever used an HCV before, you know just how simple this is. It's the easiest to adjust drain check valve available and can handle elevation extremes up to 11 m. However, what you probably don't know is that it is now constructed to schedule 80 specifications, making it more durable and long-lasting than ever.
