Moore is newer than most of Oklahoma – 39% of its 24,995 units predate 1980, which in practice means the 1978-1995 polybutylene window – gray plastic supply line that fails at the fitting. Heating runs 68% utility gas to 30% electric. 39% has been built since 2000, so this is really two housing markets in one place and what fails depends on which half you are in.

What we get called for in Moore

Toilet runs intermittently with nobody near it

The flapper has hardened. A replacement is a few dollars and about ten minutes with the supply shut off. Worth doing before you call anyone.

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.

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.

What this costs here

Aerator or flapper replacement	$0 — do it yourself
Angle stop replacement	$140–225 per stop
Water heater, 40gal gas, installed	$1,300–2,000
Sewer camera inspection	$175–350
Lateral replacement, 40ft	$5,500–9,500

Ranges reflect Moore-area labor against a $204,500 median. Two of these you can do yourself for nothing.

Check these first

• 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.
• Shut the main and watch the meter for fifteen minutes. If the dial still moves, you have a leak on the house side.
