Use this method only if you have a steep bank such that the backhoe cannot reach deep enough to maintain a level trench cut to the riser or if you have a long uphill run. The idea is to maintain a 5' deep trench cut, from the top of the ground, to the riser. Then you must figure out the correct angles when you install the hydrant. Problems 1. It is hard to figure correct angles for the joints 2. It is hard to dig the trench to match the angle. 3. It takes more time to install 6" NFT Male or as per Fire Chief Concrete Pad See Detail this Sheet 6" Schedule 40 PVC Pipe Angle? Angle?
