Stillwater is newer than most of Oklahoma – 44% of its 22,353 units predate 1980, which in practice means the 1978-1995 polybutylene window – gray plastic supply line that fails at the fitting. Stillwater leans electric for heat, 48% against 48% gas. 3.3% of Stillwater heats with bottled or tank propane, which is high for a place this size and points to a fringe that is not on the gas main.

What we get called for in Stillwater

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.

Gray plastic supply line, leaking at the fitting not the pipe

Polybutylene, installed 1978–1995. The pipe itself often survives; the acetal insert fittings do not. Failures cluster at connections and behind walls. Insurers increasingly decline or surcharge homes still on it, which is worth knowing before you renew.

Warm patch on the slab, water bill up, nothing visible

Hot-side slab leak on copper. The warm spot is diagnostic. Do not let anyone break concrete before a leak locate has been run.

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 Stillwater-area labor against a $237,200 median. Two of these you can do yourself for nothing.

Check these first

• Lift the toilet tank lid and put a few drops of food coloring in. Color in the bowl within ten minutes means the flapper.
• Find your main shutoff and turn it now, while nothing is wrong. A seized valve is a problem you want to discover on a Tuesday.
• Read the serial sticker on the water heater. Most encode the manufacture date in the first four characters.
