47% of Oklahoma City’s 306,366 housing units predate 1980, which in practice means copper supply that is fine and original cast-iron stacks that are not. Heating runs 57% utility gas to 40% electric. Housing value sits at $231,300 against 306,366 units, which sets what a repair-or-replace decision looks like here.

What we get called for in Oklahoma City

Cast iron stack weeping at the joints

Lead-and-oakum hub joints at seventy years. The leak is usually below the floor before it shows above it.

Angle stop under the sink will not close

Multi-turn stops from this era seize. Test each one before you need it. Replacing them is inexpensive when it is planned and expensive when it is not.

Water heater rusting at the base in an attached garage

Standard placement for this era. Check for a drain pan and a routed discharge. If neither exists, that is worth fixing before the tank goes.

What this costs here

Aerator or flapper replacement	$0 — do it yourself
Angle stop replacement	$165–260 per stop
Water heater, 40gal gas, installed	$1,500–2,400
Sewer camera inspection	$200–400
Lateral replacement, 40ft	$6,500–12,000

Ranges reflect Oklahoma City-area labor against a $231,300 median. Two of these you can do yourself for nothing.

Check these first

• Read the serial sticker on the water heater. Most encode the manufacture date in the first four characters.
• Shut the main and watch the meter for fifteen minutes. If the dial still moves, you have a leak on the house side.
• Soak the aerator on the slow tap in white vinegar before assuming a supply problem.
