Attention Western Contractor:
Hunter Introduces Electric/Anti-Siphon Combination Valve for Residential Systems

So, what the heck is backflow and why do I need to prevent it?

Backflow is an undesirable reversal of the flow of water and other unwanted substances (e.g., industrial fluids, reclaimed water, chemical laden runoff from agricultural fields, etc.) from any source into the distribution pipes of a potable water system. At a typical residential or commercial installation, the actual problem is called backsiphonage. Because sprinkler heads are located below ground level, water which may have been in contact with fertilizers or other potentially toxic applications can be siphoned back through a leaky valve and enter the potable water supply.

Sounds pretty nasty, right? Well, it is definitely something that you don't want affecting your water system, so what can you do about it?

Simple, you need a backflow prevention device.

A backflow prevention device like Hunter's Pro-ASV anti-siphon valve contains a moving element inside which, during flow, keeps water from spilling from the unit and, during cessation of flow, drops down to provide a vent opening. The result is safe, uncontaminated water where you expect it.

Prevention for Every Zone

If you live in a part of the country that uses the type of backflow preventer that is attached to an electric valve, Hunter now has one for you. The new Pro-ASV meets the needs of irrigation systems that require backflow prevention for every zone. The Pro-ASV offers simple operation and trouble-free performance for both residential and light commercial sites, while eliminating the need to install a separate backflow preventer.

This convenient all-in-one unit offers a whole host of features that professionals have come to expect from a Hunter valve – a rugged diaphragm that provides a leak-proof seal, internal bleed for manual operation, stainless steel hardware and springs, stainless steel bonnet screws, and heavy-duty PVC construction that is both corrosion- and UV-resistant. The Pro-ASV also includes flow control, allowing precise adjustment of the flow plus manual shutoff.

The Pro-ASV also offers a glue-in-place slip version that can allow you to quickly install an entire manifold without need for extra fittings or teflon tape, a user-friendly feature that no other major manufacturer offers. Combine this with the fact that the Pro-ASV has been specifically sized and designed to be retrofit-comaptible with all popular brands of anti-siphon electric valves, and you have the perfect choice for those looking to upgrade to Hunter.

For a cost-effective solution that also provides the proven reliability that meets all the listing requirements of the regulatory agencies that set the standards for anti-siphon valves, you can depend on the Hunter Pro-ASV.
