Helped troy upsell hydrojet, please add spiff or let me know what happened to call Also found brian s did not install a prv when he bored the new water service. Installed a new prv and asrd brian. Spoke with James about this Arrived to find customer stating water would back up in basement laundry sink. Pulled trap and snaked line about 40 foot. Pulled back grease and hair and lint. Reccommended moving washer over or extending discharge line to slop sink so they can put a lint sock on it to catch the lint. Troy was on site before I left and I believe he set up for a hydrojetting on Thursday.
