What's so bad about a PVC System?
Nothing at all. PVC is great for many kinds of sprinkler installations. Lawn Belt is simply easier to install and maintain. Because of its flexibility, Lawn Belt can take extreme temperatures and survives even the harshest winters.
Lawn Belt is more like a garden hose than a PVC pipe. It is also made from polyethylene plastic and resin and is diamond in shape. The oval opening which the water flows thru is equal to about 5/8" diameter.
