Plumbing help in Frisco, TX
Freeze RiskStorms
Frisco is one of the newest large cities in Texas: the median home was built in 2010, so most plumbing here is PEX supply line, plastic drains and first-generation water heaters now reaching replacement age. Its water comes through the North Texas Municipal Water District from Lavon Lake and Bois D'Arc Lake.

What Frisco homeowners call plumbers about
- Water Heater Replacement
Tanks installed during the 2000s and 2010s building boom are reaching the 10 to 15 year mark together, so many homes are replacing the original heater.
- Slab Leak Repair
Homes sit on slabs over expansive Blackland Prairie clay, which moves with drought and rain and stresses the lines underneath.
- Water Softener Installation
Lake water from the NTMWD system leaves scale on fixtures and in water heaters, so softeners are a common add-on in new homes.

Frisco plumbing questions
Where does Frisco's tap water come from?
From the North Texas Municipal Water District, which treats water from Lavon Lake, Bois D'Arc Lake and several other reservoirs before delivering it to Frisco.
My Frisco home is only 10 years old. Why is the water heater failing?
Tank water heaters commonly last about 8 to 12 years, and less with hard water and no flushing. Many Frisco homes still have the heater the builder installed. See how long water heaters last.
Are slab leaks a problem in new Frisco homes?
They can be. Clay soil movement and the water lines under the slab, rather than the age of the home, are what drive most slab leaks in North Texas.
How do I check a Frisco plumber's license?
Look the plumber up on the Texas State Board of Plumbing Examiners license search before work starts.
