A friend of mine said he'll bring his small back hoe and trench the 70' for $100, cheaper than a rental and no trailer or delivery charges. I thought about rmc but this particular job just seems easier to run pvc right out of service panel through basement and out with an LB, plastic is just so darn easy to work with and cheap, 1" is .32 cents per foot. One question I have though is concerning the friend with the back-hoe, if he isn't insured I think myself or the homeowner might be taking on undue liability, what are some thoughts on this? Do you guys ever get help from buddies, etc and consider the liability involved.
