Customer stated drains are backing up and there is a leak in the crawlspace. Provided estimate to attempt to clear mainline and customer agreed to work. Used cable through septic inlet baffel. Used camera finding mainline has been crushed at about 40 feet from septic tank. Used hydro jetting towards blockage and got mainline to drain to septic. Crushed pipe is still there and will need to be replaced. Provided estimate to install clean out outside and replace crushed section of mainline. Called utility locates and will schedule job when locates are completed. Customer is going to replace waste and overflow. Dig #22501494 No warranty or guarantee on drain cleaning.
