Plumbing Checklist for Nevada Homes (Before Vacation Season Begins)

The Checklist

12 Things to Check Before Summer Hits

1. 01
   Flush Your Water Heater and Clear Sediment Buildup

   Southern Nevada's water is among the hardest in the country, and sediment accumulates inside water heater tanks faster here than almost anywhere else. As summer begins and hot water demand increases with more frequent showers, laundry cycles, and guest turnover, a sediment-laden tank works harder, heats less efficiently, and runs a much higher risk of failure. Flush the tank in April or early May, inspect the anode rod, and test the pressure relief valve before the season gets fully underway.

2. 02
   Inspect All Supply Lines Under Sinks and Behind Toilets

   Braided stainless supply lines degrade faster in extreme heat, and Las Vegas summers accelerate that process significantly. Before the high-use season begins, check every supply line under kitchen and bathroom sinks and behind toilets for signs of bulging, corrosion, or discoloration. For rental properties cycling through summer guests, a line failure mid-stay can cause extensive water damage and immediate loss of rental income. Replacing aging lines proactively costs a fraction of what a burst line will.

3. 03
   Test All Toilet Flappers and Fill Valves for Silent Leaks

   A faulty toilet flapper can silently waste up to 200 gallons of water per day. During summer, when water usage across the household is already elevated and utility rates reflect peak demand, undetected toilet leaks translate directly into inflated bills. The test is simple: add a few drops of food coloring to the tank and wait ten minutes without flushing. If color appears in the bowl, the flapper needs replacing. For rental units preparing for summer occupancy, this is one of the fastest and cheapest fixes on the list.

4. 04
   Service Your Irrigation System Before Peak Watering Season

   Landscaping in Las Vegas requires significantly more irrigation from May through September, and that means irrigation systems run longer and more frequently than any other time of year. Before the season begins, inspect all drip lines, spray heads, solenoid valves, and backflow preventers for leaks, clogs, or damage caused by winter temperature swings. A poorly calibrated or leaking irrigation system during peak summer can spike a water bill by hundreds of dollars in a single month and cause foundational soil saturation that is expensive to address.

5. 05
   Clear Drain Lines and Address Any Slow Drains Now

   Slow drains are a known annoyance during normal conditions. During summer, when rental properties are at full occupancy and residential households are hosting guests, they become urgent problems. A partial clog in summer heat also creates conditions for foul odors that travel quickly through drain vents into living spaces. Run water through every drain in the home before the season starts, including utility room and garage floor drains, and have any sluggish lines professionally cleared before bookings or high-use periods begin.

6. 06
   Inspect Outdoor Hose Bibs and Pool-Adjacent Plumbing

   Outdoor plumbing fixtures take a beating from the temperature extremes of a Las Vegas summer. Hose bibs exposed to direct sun on south and west-facing walls are particularly vulnerable to seal deterioration and connection loosening. For homes with pools, inspect the plumbing connections at the equipment pad, including pump fittings, return line unions, and any PVC joints that may have shifted during winter. A slow pool equipment leak running all summer adds up fast on both a water bill and a potential structural repair invoice.

7. 07
   Check for Slab Leak Warning Signs Before the Ground Heats Up

   Nevada homes built on concrete slabs are highly susceptible to slab leaks, which occur when copper pipes embedded in the concrete expand and contract with temperature changes until they crack or separate. The ground temperature in Las Vegas during summer amplifies this stress dramatically. Before peak heat arrives, walk your home's flooring and note any warm spots, unexplained damp areas on tile, or unusual increases in your water bill with no change in usage habits. Early detection of a slab leak in spring costs a fraction of what an unaddressed one costs by August.

8. 08
   Restock and Test Your Water Softener System

   Las Vegas municipal water consistently ranks among the highest mineral content supplies in the United States. A properly functioning water softener protects water heaters, fixtures, and appliances from accelerated scale buildup. As summer begins and water usage increases, the softener cycles more frequently and depletes salt reserves faster than other seasons. Verify the salt reservoir is full, run a manual regeneration cycle, and check the bypass valve and resin tank for any issues before summer demand kicks in. A softener that fails in June will cause months of hard water exposure across every fixture in the home.

9. 09
   Inspect Washing Machine Hoses and Connections

   Washing machines run more frequently during summer in any occupied household, and in rental properties with back-to-back guest stays, the usage rate during peak season can be substantial. Standard rubber supply hoses degrade faster in high-heat environments and are one of the most common causes of serious in-home flooding. Inspect both hot and cold supply hoses for cracking, stiffness, or bulging at the fittings, and replace any that show wear. Braided stainless hoses are an inexpensive upgrade that significantly reduces failure risk during high-use months.

10. 10
    Recaulk Wet Areas in Bathrooms and Around Kitchen Fixtures

    The dry heat of a Las Vegas summer pulls moisture out of caulk and grout faster than nearly any other climate in the country. By the time summer arrives, caulk around tubs, showers, and sink basins that was applied a year or two ago may already be cracking or pulling away from surfaces. Deteriorated seals allow water to seep into wall cavities and subflooring, where it causes mold and structural damage that develops slowly and invisibly. Inspect and replace failed caulk before summer begins, especially in rental units where bathrooms will be used heavily throughout the season.

11. 11
    Verify Water Pressure Is Within Safe Range

    High water pressure is a common and underappreciated problem in Las Vegas Valley homes. Pressure above 80 PSI stresses every joint, fitting, and appliance connection in the plumbing system, and that stress accelerates during summer when city supply pressure can fluctuate with regional demand spikes. Purchase an inexpensive pressure gauge at any hardware store and attach it to a hose bib to check your home's reading. If pressure is above 80 PSI, a pressure reducing valve adjustment or replacement is a straightforward fix that protects the entire plumbing system through the high-demand months ahead.

12. 12
    Schedule a Professional Plumbing Inspection for Rental Properties

    For property managers and landlords preparing units for summer rental season, a professional pre-season plumbing inspection is the single most effective way to catch problems before guests do. A licensed plumber can pressure-test supply lines, inspect the water heater, assess drain flow, check for early signs of slab activity, and provide documentation of the property's condition prior to peak occupancy. In a market where summer rental rates and guest expectations are both at their highest, a plumbing failure mid-season is one of the most damaging and entirely preventable outcomes a rental property can face.
