Supply lines in attics and garages
The McKinney airport station logs 47.8 freezing nights in a normal year, about twice the 23.1 at Dallas Love Field, according to NOAA. Lines to an attic or garage heater split first, so we check and wrap them on a leak call.
Inside the tank, settling at its base
The North Texas Municipal Water District calls its treated water moderately hard because of minerals in Lavon Lake. Those minerals settle as sediment and pack around the drain spigot, so a valve that won't close after flushing is a common call.
The cold and hot lines entering the heater
Many newer homes run PEX tubing to the heater, joined with crimp rings and brass adapters. A drip at one of those adapters is a connection repair, and we replace the fitting while the tank stays put.
The tank shell, often low on the jacket
Half of McKinney's homes were built in 2007 or later, according to the Census Bureau. Many still have the heater the builder fitted, and an original tank weeping rust is usually at the end of its life.
We sort each McKinney call by the spot that is wet. While you wait, read our first steps when it leaks guide.
Water running down the jacket from above often comes from a nipple, an adapter or the shut-off valve. We dry the fittings, find the weeping joint and replace it.
A drain valve clogged with sediment drips into the pan. We flush out what we can, then fit a new valve so the tank drains properly next time.
The relief valve opens when the water inside gets too hot or the pressure climbs too high. We gauge your house pressure and test the expansion tank before we swap the valve itself.
On an attic heater, the pan and its drain line are what stand between a drip and a stained ceiling. We clear or repair a blocked pan drain along with the leak that filled it.
Rusted steel can't be patched. We drain and remove the old heater and fit a gas or electric replacement, tank or tankless, built to the code McKinney inspects against.
McKinney spells out its permit rule for water heaters, so a replacement here comes with a permit and an inspection.
The City of McKinney names water heaters among the home repairs that need a permit, and its fee schedule carries a separate line for residential water heater permits.
Texas Occupations Code section 1301.255 says plumbing installed under an adopted code has to be inspected by a plumbing inspector. City of McKinney Building Inspections handles that step for a new heater.
The Texas State Board of Plumbing Examiners tells homeowners to ask their city plumbing inspection office about permits and inspections. On a repair call, we tell you up front whether we expect the city to be involved.
The part that failed and the heater's location move a McKinney bill most; typical Texas ranges and the city permit fee are in our homepage cost table.
| Factor | What raises it | What lowers it |
|---|---|---|
| Leak source | A rusted-through shell means a new heater | A valve or connection is a part repair |
| Heater location | Attic platforms with tight access | A garage heater on an open slab |
| Sediment | A packed tank that won't drain | A tank flushed in recent years |
| Permit | A city permit on a replacement | A part repair with the tank left in place |
| Pressure | A missing or failed expansion tank to fix too | House pressure already in range |
