Plumbing: The Maintenance Category Owners Underestimate Most
The Category That Quietly Wrecks Rental P&Ls
Ask most landlords what worries them, and they'll say HVAC, roofs, or tenant damage. Plumbing rarely makes the list — until a supply line lets go at 2 a.m. and takes the flooring, baseboards, and downstairs ceiling with it.
Water heaters: replace on age, not on failure. The single most predictable plumbing failure in a rental is the water heater. Gas tanks last 8 to 12 years; electric tanks last 10 to 15. Past year eight, the risk curve steepens sharply.
The replacement cost is not the scary number. A 50-gallon gas tank runs $1,600 to $2,800 installed, and a 50-gallon electric tank runs $1,200 to $2,200. The scary number is what happens when a 12-year-old tank ruptures in an occupied second-floor unit. The Insurance Information Institute puts the average household water damage or freezing claim at roughly $12,514. Deductible, uncovered plumbing repair, lost rent during dry-out, and tenant belongings claims stack on top.
Two habits change the math: check the manufacture date on every heater at turnover, and plan a proactive swap between years 10 and 12 instead of waiting for a leak.
Supply lines and angle stops: the $8 parts that cause $8,000 losses. Braided steel washing machine hoses, toilet supply lines, and dishwasher connectors are the most common failure points in a rental. Rubber hoses harden and split. Cheap plastic angle stops seize and crack when a tenant tries to shut off water.
Replace washing machine hoses every five years. Swap plastic angle stops for quarter-turn brass valves during any turnover where the fixtures look original. The parts cost less than a pizza. Fixing a burst pipe runs from $150 for simple jobs to over $4,000 for complex ones — and that's before the drywall, flooring, and mold work that follow.
Drain maintenance nobody thinks about until it's too late. Kitchen and main line clogs are the number one after-hours call in Lubbock rentals. Grease, hair, and root intrusion in older mainlines around Tech Terrace and the medical district cause backups that damage flooring and trigger emergency plumber rates.
A camera inspection on any home built before 1985, plus hydro-jetting or cabling every three to five years on properties with a history of backups, is cheaper than one Saturday-night emergency call and a soaked bathroom.
Freeze Prep Is Not Optional in West Texas
The February 2021 freeze taught every Lubbock landlord the same lesson: uninsulated hose bibs, exposed pipes in unheated garages, and vacant homes with the heat off are the failure points. Insurance claims for frozen-pipe water damage average $10,000 to $15,000, and severe cases can exceed $50,000 when flooding destroys flooring, walls, or electrical systems.
Insulated hose bib covers cost about $3 each. Pipe insulation on exposed garage lines runs under $20 per property. Every occupied home should have written freeze instructions in the tenant portal before December 1. Vacant homes get the water shut off at the main and the system drained — not the heat left on 55 and hoped for the best.
One wrinkle owners miss: the pipe itself is almost never covered by insurance. The insurer pays for the damage the water caused, not the plumbing repair. Replacing the burst section, the fittings, and the surrounding pipe is a maintenance expense.
How Meridian Handles It
We recommend that every property gets a plumbing baseline at onboarding: water heater age, supply line condition, angle stop type, and hose bib coverage. We recommend proactive water heater replacement at year 10, and a freeze-prep checklist and tenant notification before the first hard freeze. Spending $200 on prevention beats a $12,000 claim.
