had a directional boring sub come in for 1 road crossing, 2 creek crossings.....on one creek crossing, punched thru, i provided the 6" yellomine pipe. about 40' into the pull back, he started having problems, pretty good sized vermeer directional bore unit. with his anchor augers stuck ALL the way down, he still had us chain our excavator to his bore unit to keep it in place. i know nothing about boring, just knew something wasn't right. hooked it up, the main wouldn't pressure up. pressure tested lines both ways from bore...all's cool....the 200' of yellomine under creek was leaking. he hum hawed around about coming back to rebore it, so today, we stuck an excavator on each side of the creek,and hogged it in. bear in mind, this is a sand/clay, sand/clay/sand/clay in 6" increments strata that makes it very hard to dewater, that is why i hired him to do the bore...anyway....he says he won't charge me for that bore, but i feel he should pay for the 200' of yellomine still under the creek that has a break in it somewhere...at least part of it anyway..i think he didn't have a big enough reamer on or something, hellifino...my thoughts are...i hired a "pro"...to do this for me, he should have known there were problems, and restuck the hole, or something, tried again....thoughts? am i out of line thinking he should reimburse me for part of the cost of that pipe?
