How to Protect the Home and Plumbing While Traveling This Summer

With summer in full swing, many homeowners are packing their bags and preparing for well-deserved getaways. However, before heading out the door, taking a few precautions to protect the home’s plumbing system can prevent the nightmare of returning home from vacation to water damage from a burst pipe or an unnoticed leak. This post discusses the steps homeowners should take before leaving for vacation this summer, from preparing the water heater to shutting off the main water supply.

Prepare the Water Heater for Vacation

One common question homeowners have before traveling is whether to turn off the water heater. While it may seem like a good way to save energy, turning off a water heater before a vacation typically isn’t recommended for short trips. The energy savings are minimal, and shutting the unit down can actually lead to additional problems. When a water heater sits idle with water inside, the temperature drops to a range that allows bacteria, including Legionella, to grow. This can create potential health hazards when the system is restarted upon returning home.

A better option is to set the water heater to vacation mode, a feature available on many units. Alternatively, homeowners can manually lower the thermostat to reduce standby heat loss and save on utility costs. The only scenario where it makes sense to turn off a water heater is when the home will be empty for an extended period of longer than a month. In that case, the unit should also be drained completely to prevent stagnant water from becoming a breeding ground for bacteria.

Check for Leaks Before Leaving

A small drip under a bathroom sink or a slow leak near a toilet may seem insignificant, but left unattended for days or weeks, these minor issues can escalate into serious water damage. Homeowners should check key areas throughout the home, including under sinks, around toilet bases, near appliance connections, and along visible pipes.

There are also several warning signs that can indicate a hidden water leak, such as low water pressure, water stains on ceilings or walls, signs of mold growth, musty odors, and higher-than-expected water bills. If any of these signs are present, calling a professional plumber for water leak repair before leaving is crucial. Resolving leaks before a trip can prevent expensive water damage, mold remediation costs, and excessive water bills that would otherwise accumulate while the home sits empty.

Shut off the Water

For homeowners planning an extended trip, turning off the home’s main water supply is an effective way to prevent flooding and water damage caused by burst pipes or leaks that may develop while away. By locating and closing the main water shut-off valve, the risk of water flowing through the plumbing system and causing damage is eliminated. This simple precaution provides peace of mind during a long trip.

The main water shut-off valve is usually found near where the main water line enters the home, often in a basement, utility room, or near the water meter. Homeowners who are unfamiliar with the location of their shut-off valve should locate it before leaving on their trip. Taking some time to shut off the water supply can prevent the costs of high water bills and water damage repairs from a leak or burst pipe.
