Drought-Proof Your Pipes & Appliances

This guide helps you protect your home’s plumbing and water-using appliances during a drought, when water pressure can fluctuate and sediment in supply lines becomes more concentrated. You’ll learn practical steps to prevent damage from low pressure, airlocks, and sediment buildup, and how to keep your appliances running efficiently with less water. Before you start, gather a few basic tools and supplies, and always check your local water authority’s drought restrictions for any specific guidance.

What You’ll Need

• Adjustable wrench
• Screwdriver set
• Bucket or large container
• Clean rags or towels
• Pipe insulation (foam or fiberglass)
• Teflon tape (plumber’s tape)
• Water pressure gauge (thread-on type)
• Water filter cartridges (for whole-house or point-of-use filters)
• Food-grade hydrogen peroxide or white vinegar (for cleaning)
• Lubricant (silicone-based, for valves)

Step-by-Step

1. Check your water pressure. Attach a water pressure gauge to an outdoor spigot or the main water line. Open the valve fully and read the gauge. Normal household pressure is 40-60 psi (2.8-4.1 bar). If it’s above 80 psi (5.5 bar), you risk damaging pipes and appliances; if it’s below 30 psi (2.1 bar), you may have low-flow issues. Install a pressure regulator if needed, or contact your water utility.
2. Inspect all visible pipes for leaks. Look under sinks, around the water heater, and along exposed basement or crawlspace pipes. Check for dampness, corrosion, or mineral deposits. Tighten loose fittings with a wrench, and wrap any dripping joints with Teflon tape. Replace cracked or rusted sections immediately to avoid burst pipes when pressure fluctuates.
3. Insulate exposed pipes. During droughts, temperature swings can be more extreme. Wrap foam pipe insulation around all exposed hot and cold water pipes, especially in unheated areas like garages or attics. This prevents freezing in winter and reduces heat gain in summer, which also saves water by reducing the time you wait for hot water.
4. Flush your water heater. Sediment settles at the bottom of the tank, reducing efficiency and causing corrosion. Turn off the power or gas to the heater, connect a hose to the drain valve, and drain a few gallons into a bucket or drain. Do this every 6-12 months, or more often if you have hard water. Close the valve, refill, and restore power.
5. Clean or replace filters. Sediment and minerals become more concentrated as water levels drop. Check and clean or replace filters in your whole-house filtration system, refrigerator water dispenser, and washing machine inlet screens. For washing machines, unscrew the hoses from the back and clean the small mesh screens with a brush or vinegar.
6. Protect your washing machine. Use the correct amount of detergent for your water hardness and load size—too much soap creates extra suds that can damage the machine. Also, check the rubber seal on front-loaders for mold or cracks. Run an empty hot-water cycle with a cup of vinegar or hydrogen peroxide monthly to clean the drum and hoses.
7. Protect your dishwasher. Scrape food off dishes instead of pre-rinsing with running water. Check the spray arms for clogs and clean the filter at the bottom of the tub regularly. If your dishwasher has a food disposer, run it briefly to clear any buildup.
8. Lubricate valves. Turn each shut-off valve (under sinks, behind toilets, at the main) a quarter turn to keep them from seizing. Apply a silicone-based lubricant to the stems. This ensures you can shut off water quickly in an emergency, which is critical when drought conditions make supply unreliable.
9. Consider a smart leak detector. Install a simple battery-powered leak sensor near your water heater, washing machine, and under sinks. These devices alert you to leaks early, preventing costly water damage—especially important when you might not be using as much water and leaks go unnoticed.
10. Reduce water pressure during peak usage. If your area has voluntary or mandatory water restrictions, avoid running appliances during peak hours (usually morning and evening). This reduces stress on the system and lowers the risk of pressure surges that can damage pipes.

Common Mistakes

• Ignoring low pressure. Many people assume low pressure is normal during a drought, but it can be a sign of a leak or a failing pressure regulator. Check with a gauge and investigate.
• Over-tightening fittings. This can crack plastic or brass fittings. Tighten until snug, then give a small extra turn—no more than a quarter turn.
• Forgetting to drain the water heater. Sediment buildup is a leading cause of premature water heater failure. Skipping this step reduces efficiency and can cause popping noises or even tank leaks.
• Using the wrong filter. A filter with too fine a micron rating can restrict flow and increase pressure on your pump or plumbing. Check the manufacturer’s recommendation for your water quality.
• Not checking the main shut-off valve. If you don’t know where it is or if it’s stuck, you can’t stop a major leak quickly. Locate it and test it annually.

Tips

• During a drought, water quality can change. Test your water for hardness and sediment, and adjust your water softener settings accordingly.
• Use the “eco” or “water-saving” cycle on your washing machine and dishwasher. These cycles use less water but still clean effectively.
• Insulate your hot water pipes to reduce the time it takes to get hot water, saving both water and energy.
• If you have a well, check your pump’s pressure tank. The air pressure should be about 2 psi below the pump’s cut-in pressure. Adjust if needed.
• Keep a bucket in the shower to catch cold water while you wait for it to warm up. Use it to water plants or flush the toilet.

Troubleshooting

• Water pressure is still low after checking the gauge. If your gauge reads below 30 psi, check for a partially closed main valve. If it’s fully open, there may be a leak in your service line or a clogged pressure regulator. Contact your water utility or a plumber.
• Water heater makes rumbling noises. This is usually sediment buildup. Drain it again, and if the noise persists, the heating elements may be coated with scale. You may need to descale the tank with a vinegar solution or replace the elements.
• Washing machine won’t fill or drains slowly. Check the inlet screens for clogs. If they’re clean, the problem might be a faulty water inlet valve or a kinked hose. Also, check the drain hose for blockages.
• Dishwasher leaves spots or film. This is often due to hard water. Use a rinse aid and increase the water softener setting. If the spray arms are clogged, clean them with a toothpick.
• Pipes make banging noises. This is called water hammer, often caused by high pressure or loose pipes. Install water hammer arrestors or secure loose pipes with clips. If pressure is high, adjust your pressure regulator.

Frequently Asked Questions

Will low water pressure damage my appliances?

Low pressure itself usually won’t damage appliances, but it can cause them to run longer or not fill properly, leading to wear. More importantly, pressure fluctuations can cause water hammer or suck sediment into valves. Monitoring and filtering helps.

How often should I flush my water heater during a drought?

Every 6 months is a good rule, but if you notice sediment in your hot water or hear rumbling, do it more often. During a drought, sediment concentration can be higher, so check every 3-4 months.

Can I use a pressure washer during a drought?

Many areas restrict outdoor water use during droughts. Check local rules. If allowed, use a pressure washer with a shut-off nozzle and only on impervious surfaces like driveways, not on lawns.

Should I turn off my water heater if I’m away?

If you’re away for more than a few days, turning off the water heater can save energy and reduce the risk of leaks. But make sure to drain it if freezing temperatures are possible. Otherwise, set it to vacation mode if available.

How do I know if my pipes are frozen during a winter drought?

If you turn on a faucet and only a trickle comes out, or no water at all, you may have a frozen pipe. Feel the pipe for cold spots and look for frost. Thaw slowly with a hair dryer, starting from the faucet end, and never use an open flame.

Do I need a water softener during a drought?

If you have hard water, a softener is still beneficial to protect appliances from scale buildup. However, softeners use water for regeneration. Consider a high-efficiency model or a dual-tank system to minimize water use.
