Trimom -

This is absolutely the most difficult part of your install. I feel your pain, we did it in April. We had our neighbor help us. He works for the local municipal water company and has been laying pipe for 14 years. Knows about level, knows about digging. First he used a lazer level and shovel to dig the long way. Then he used the 3 point/3 circle technique described in our installation manual which you can find here: http://www.cantar.com/product.asp?ProdID=66 . He started, ended, and referred often to his transit. It is dead on level in all directions and I wouldn't toy with anything less.
