It's now that time of the season to prepare for the cold Texas winter this checklist has been formulated as a reference guide and may not be construed as a complete list.
Fall Waterline Checklist
Insulate exposed Piping If you have any exposed water or drain piping at all in uninsulated spaces such as in a crawlspace, attic, outside walls, etc., make sure to insulate them with foam insulation at a minimum. Ideally you should wrap them with electrical heating tape first, then insulate them.
Exterior Faucets Known as hose bibbs or sill-cocks, the exterior faucet needs to have its water supply turned off inside the house, and you also need to drain water from it by opening up the exterior faucet. You may also want to consider an insulated cover for the hose bibb. And remember to disconnect your garden hoses from the sill cocks or outside faucets and drain them if you store them outside.
Seasonal Shut Down If you are shutting down a property for several months you should always shut off the water supply and drain the plumbing system. If a leak were to occur without occupancy, the damage could be catastrophic.
Sprinkler System The sprinkler system should not be overlooked in preparing your home for winter. Have your sprinkler system winterized prior to freezing conditions. Winterizing should include turning off the water supply and blowing compressed air through the sprinkler lines to purge them of water and prevent them from freezing and bursting.
