Preventive plumbing tips are provided to avoid working with water in cold weather. If these tips are followed before a cold spell, homeowners will be able to relax and know that expensive repairs will not be necessary.
If a cabin or summer cottage or home will be left unheated during the winter, take steps to prevent pipe damage due to freezing water. In addition to the steps offered in this week’s plumbing tips, say the Santa Cruz plumbing experts, turn off the main shutoff valve and open a pipe nearby to let water drain out.
Next, drain all water-using appliances, such as the dishwasher an clothes washer. If the cabin or rental property has hot-water heat, drain the heating system. Some summer homes have small drain valves on the pipes; open them.
