Hurricane Season Plumbing Prep for Homeowners

Hurricane season in Texas runs from June 1 to November 30, with the highest risk in August and September. For homeowners in Katy and Houston, preparation means more than stocking up on bottled water and boarding up windows. Your plumbing system needs special attention to withstand heavy rain, flooding, and power outages.

As local experts with more than 30 years of plumbing experience, MET Plumbing has seen firsthand how storms like Hurricane Harvey left families dealing with sewer backups, flooded garages, and broken water heaters. The good news is that with a clear checklist, you can reduce your risks and keep your home safe.

This guide explains the most important steps for hurricane plumbing preparation in Houston and Katy, TX.

Why Plumbing Prep Matters in Hurricane Season

• Heavy rainfall and flooding puts pressure on drains and sewer systems. Clogged drains or damaged sewer lines can push water back into your home.
• Power outages affect plumbing equipment. Without backup power, sump pumps, well pumps, and even tankless water heaters may stop working.
• Outdoor fixtures are vulnerable. Garden hoses, irrigation heads, and exposed pipes can break loose during high winds.

Protecting your plumbing before a storm means protecting your home from costly water damage, mold, and unsafe conditions.

Step 1: Clear Drains and Gutters

Blocked gutters and drains are one of the most common causes of flooding around foundations. During heavy storms, water must move away from your house quickly.

• Remove leaves, dirt, and debris from gutters and downspouts.
• Check outdoor yard drains and storm drains near your property for blockages.
• Consider installing gutter guards or drain covers for long-term protection.

Question to ask: Have you checked every drain and gutter this season, including yard drains?

Step 2: Inspect and Test Your Sump Pump

If your home has a sump pump, it’s your first line of defense against rising groundwater.

• Test it by slowly pouring water into the pit until the pump activates.
• Listen for any unusual noises and confirm that it shuts off properly after draining.
• Install a battery backup system to keep the pump working during power outages.

If you live in a flood-prone part of Katy, TX, a sump pump inspection should be part of your annual storm drainage maintenance.

Step 3: Install or Service a Backwater Valve

Sewer backups are a serious problem during hurricanes. When municipal systems are overwhelmed, untreated sewage can flow back into homes.

• A backwater valve prevents sewage from reversing into your plumbing.
• Hire a licensed plumber to inspect or install this valve.
• Have it serviced annually, ideally before hurricane season begins.

Question to ask: Do you already have a backwater valve, and has it been checked recently?

Step 4: Secure and Elevate Your Water Heater

Water heaters in garages or ground-level closets are especially at risk during floods. A damaged heater can leak, stop working, or even become unsafe.

• Strap your water heater to the wall to prevent tipping during strong winds.
• If possible, raise the unit on a platform to keep it above potential floodwater.
• For added protection, install a drain pan with a sump pump connection.

MET Plumbing specializes in traditional and tankless water heaters and can elevate or replace your system before the season peaks.

Step 5: Locate and Test Your Main Water Shut-Off Valve

Every homeowner should know how to shut off the main water supply.

• The valve is usually located near the street or where the main line enters your home.
• Test it by turning it gently to make sure it doesn’t stick.
• Teach all family members how to operate it in case of emergency.

If you must evacuate, shut off the valve and turn off the water heater to prevent leaks or pressure damage while you’re away.

Step 6: Store an Emergency Water Supply

When storms hit, water service may be disrupted or unsafe to drink.

• Store at least three days of drinking water per person in your home.
• Fill bathtubs, sinks, and large containers with water for flushing toilets and cleaning.
• Keep bottled water on hand for drinking and cooking.

Step 7: Inspect Sewer Lines and Septic Systems

Sewer line damage often worsens during heavy rain. Warning signs include:

• Slow-draining sinks or showers.
• Unpleasant sewer odors.
• Gurgling toilets.

Schedule a video inspection before hurricane season if you’ve noticed any of these issues. If you have a septic tank, ensure the area around it is clear and that it isn’t showing signs of overflow.

Step 8: Protect Outdoor Plumbing Fixtures

High winds can turn outdoor fixtures into projectiles.

• Disconnect and store garden hoses.
• Remove or secure irrigation heads.
• Cover exposed pipes with insulation or weatherproof sleeves.
• Bring portable fixtures indoors.

Taking an hour to secure these items can prevent broken pipes or costly yard flooding.

Step 9: During the Storm

• Avoid flushing toilets or using drains if sewer backups are possible.
• If evacuating, shut off your main water valve and turn off your water heater.
• Do not attempt to fix plumbing during dangerous weather.

Step 10: After the Storm

Once it’s safe to return home, check your plumbing system step by step:

• Inspect all fixtures, including toilets and faucets, for leaks or low pressure.
• Slowly turn your main water valve back on to avoid sudden pressure surges.
• Look for discolored water, strange odors, or slow drains—signs of contamination or sewer issues.
• Contact a licensed plumber immediately if you notice water damage, sewage backup, or pipe leaks.
