Norman is newer than most of Oklahoma – 38% of its 56,665 units predate 1980, which in practice means the 1978-1995 polybutylene window – gray plastic supply line that fails at the fitting. The heating split is near even, 53% to 44%. Housing value sits at $250,100 against 56,665 units, which sets what a repair-or-replace decision looks like here.

What we get called for in Norman

Drain leak under the slab, PVC not copper

Glued joints in slab-embedded drain line separate as the slab moves. Less common than supply leaks and considerably more disruptive to reach.

Regulator original to the house

Pressure regulators last fifteen to twenty-five years. In this stock the original is well past that. Put a gauge on an outside tap — anything over 80 psi means it has gone.

Sillcock split after a hard freeze

Frost-free sillcocks fail when a hose is left attached over winter — water cannot drain back and the split happens inside the wall. You will find it in spring, not in January.

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 Norman-area labor against a $250,100 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.
