Upon arrival customer showed me a drain which had frozen and she has had issues with freezing in the past. Upon arrival I ran the water and there was no blockage present. There were no other issues present and the customer did not need any other work performed. The garage is drafty and unheated which caused the freeze up. To avoid this I recommend improving insulation, reducing drafts, and turning up the heat in times of extreme cold. Customer had a bottle of RV antifreeze. As a courtesy I poured it into the problematic tub drain, the lav trap, and filled the toilet tank and bowl with it followed by me flushing said toilet to fill the toilet with antifreeze. This is to prevent future freeze ups. I also showed the customer how to shut off the water main and pump in case of emergencies and for her trip to avoid flooding if the pipes freeze due to intermittent issues with her heat.
