Your 5-Minute Pre-Trip Plumbing Checklist

A quick check before any trip can be the difference between coming home to a fresh house and coming home to standing water, mold, and a headache that ruins the post-vacation glow. At EJ Home Services, we’ve seen firsthand what a missed leak or forgotten drip can turn into over just a few days. If you’re looking for a trusted plumber in Santa Clara, CA, we’re the team homeowners call when they want the job done right and the worry taken out of the equation.

Check These Spots Before You Go Anywhere

You don’t need any special tools or technical knowledge for this walkthrough. Start with the areas that tend to hide problems until they become impossible to ignore. Here’s what to look at:

• Under every sink (kitchen, bathrooms, laundry room): Look for moisture, discoloration, or soft cabinet floors.
• Around the base of toilets: Any soft flooring or water stains can signal a slow leak.
• Behind and beneath the washing machine: Hoses here are a surprisingly common source of water damage.
• Your water heater: Check for rust, pooling water, or any signs of corrosion near the base or connections.
• Exposed pipes in the garage or basement: Especially important in cooler months when temperatures drop.

If something looks off, don’t brush it aside and plan to deal with it when you get back. That’s usually when emergency plumbing calls happen, and nobody wants to get that call on vacation.

The Main Water Shutoff: Know Where It Is and Use It

Why This Step Alone Can Save You Thousands

Shut off your home’s main water supply so if anything does fail while you’re away, there’s no water flowing to make it worse.

Your main shutoff valve is typically located near the front of the house, in a utility room, basement, or garage. If you’re not sure where yours is, now is a great time to find out. Label it if you haven’t already, and make sure everyone in the household knows where it is.

Don’t Ignore Slow Drains Before You Leave

A Slow Drain Is Telling You Something

A drain that’s been sluggish for a week isn’t going to magically clear itself while you’re away. In fact, a partial blockage can worsen over time, especially if there’s any residual water sitting in the line. When you get back, that slow drain could be a full stoppage.

Run the water for a few seconds and watch how quickly it clears. If any of them seem sluggish, that’s a signal worth addressing. 

Scheduling plumbing repairs before a trip is far easier than dealing with a backed-up line on the day you return.

Give Your Toilet a Quick Inspection

Before leaving, do a quick listen. If you hear the toilet running more than a minute or two after flushing, the flapper valve may need replacing. Also check that the tank lid is secure and that the water level looks normal, not creeping up toward the overflow tube.

Water Heater and Appliance Connections

One Quick Look Can Go a Long Way

Look for mineral buildup around connections, any evidence of dripping, or rust on the tank itself.

The same goes for refrigerators with ice makers and dishwashers. The supply lines connecting these appliances are often flexible hoses that can crack or loosen over time. A quick visual check to make sure connections are snug and dry gives you genuine peace of mind while you’re away.

Working with a reliable plumbing company before you travel means you’re not guessing about the condition of these systems. You have someone who’s actually looked at them.

Questions We Hear All the Time

Q1: Should I turn off the water to individual appliances or just the main line?

A1: Shutting off the main line is the simplest and most thorough option for a trip of more than a day or two. Individual shutoffs under sinks or behind toilets are useful when you’re doing repairs, but for travel, the main valve covers everything at once.

Q2: What if I have a drip irrigation system or outdoor hose bibs?

A2: Shutting off the main indoor supply won’t affect most outdoor systems that have their own separate line or timer. Check with your irrigation setup’s manual, but in general, outdoor systems are on a separate circuit. Hose bibs, however, share the main supply, so shutting it off covers those too.

Q3: How long is too long to leave water running to a refrigerator ice maker?

A3: If you’re leaving for more than 3 to 4 days, it’s worth turning off the supply line to the ice maker. Ice will melt, the tray will refill, it can create a slow overflow situation in the freezer bin if the drainage isn’t perfect.

Q4: Is there anything special to check if I have an older home?

A4: Yes. Older homes, particularly those built before the 1980s, may still have galvanized steel or even lead pipes in some areas. These are more prone to corrosion and unexpected failure. If your home is older and you haven’t had a plumbing inspection recently, that’s worth prioritizing before you travel.

Q5: What if I find a small leak right before I leave?

A5: Don’t leave it and hope it holds. Even a slow drip can become significant over several days. If it’s a minor fixture issue, shut off the supply to that fixture specifically. If it’s anything more involved, call before you go.
