Plumbing is a vulnerable spot for a vacant house even if water is shut off for a short period.

Instead of turning off water and draining and treating pipes to prevent catastrophic fractures, many absentee homeowners will simply shut off the water to the whole house or at a toilet or sink valve.

It sounds like the right thing, but it nearly ensures that the person who next opens that valve will be mopping up water and repairing the damage. Plumbing fixture’s valve, gasket, or hose needs water to stay pliable. If it dries out, the seal will crack and will not be able to do its job. Once the valve opens and the water turns on, a leak or flood will likely follow.

The pipes can also dry out, crack, and wreak the same havoc. Water pressure can cause extreme bursts and flooding throughout your home.

How to restore water to the house.

Step 1: Remove the aerators from the kitchen and bathroom sinks before turning on the water in the house. This allows any mineral buildup to pass through and not get stuck in the aerator. Check that every faucet is turned off before turning on the water valves.

Step 2: Turn on the water supply valves under each sink. The supply valves are knobs located on the pipes under the sink. Turn the valves counter-clockwise, or to the left, to open them. Open the valve on your hot water heater as well.

Step 3: Locate an outside water faucet close to the water meter. Turn this to on so that water flows from it when you turn on the main water supply; this way you know that you have water going to the house.

Step 4: Locate the main water valve on the water meter. It probably looks like a lever you can rotate to the left to open. Rotate the valve a quarter turn, wait 20 seconds, and rotate another quarter turn. Repeat until the valve is completely open. It is important to open the main valve slowly so that the pipes in your house aren’t flooded with full-power water, which can cause leaking.

Step 5: Check that water is flowing through the exterior faucet. If it is, turn the faucet off. Go inside and listen for water flowing into the hot water tank. Do not turn on the electricity to the hot water heater until the tank is full of water.

Step 6: Turn the water faucet on at each sink. Do this slowly, and allow each faucet to run for 15 or 20 seconds. As you turn off the water, replace the aerators. Once you’ve cleared each sink, turn the valves for the toilets a quarter turn at a time until they are fully open and the tanks are filling with water. When they are full, flush the toilets. Run water into each shower and bathtub as well. When testing the different water outlets for the first time, go slowly so the pipes have time to adjust to the water and won’t leak.

Step 7: Turn off all the water outlets once the hot water tank is full. Check the water meter. If the usage meter is rotating, you may have a leak. In this instance, call a plumber. You also can do a visual tour of the inside and outside of your house to check for any leaking water.
