If water is going somewhere it should not in your McKinney home, shut off the main valve first and read the rest of this page second. Everything else can wait a few minutes. Water into a slab cannot.

Dallas Best Plumber is a free referral service, not a plumbing company. Tell us what is happening and where in McKinney you are, and we match you with a licensed, insured local plumber who takes emergency calls. We do not dispatch trucks or promise arrival windows - no honest referral service can - but we put your request in front of a pro who works your area, and the form takes about two minutes.

McKinney is unusual among Collin County cities because it has two entirely different housing stocks and therefore two entirely different emergency profiles. It is the county seat - the Texas legislature passed the act establishing it as such on March 16, 1848, according to the city's own history pages - and the blocks around the historic courthouse square hold some of the oldest housing in the county. Meanwhile most of the city west of US 75 and north toward Prosper went up during McKinney's modern boom, when the U.S. Census Bureau repeatedly named it among the fastest-growing cities in the nation.

Your first ten minutes

  1. Water off.Use the fixture's own valve if the problem is at one sink, toilet or heater. Otherwise close the main where the line enters the house, or the valve in the meter box near the street.
  2. Power off, if water is near it. Standing water near outlets, a breaker panel or an electric water heater means killing power to that area at the breaker before you walk in — and before you stand under a dripping ceiling.
  3. Gas: leave first, call from outside. If you smell gas or hear hissing at a connection, do not switch anything on or off. Get everyone out and call your gas utility from outside.
  4. Stop using water in a sewage backup. Every gallon used anywhere in the house makes it worse — no toilets, no washing machine, no dishwasher.
  5. Then tell us what happened. Your address, what is failing, whether the water is off, and the approximate age of the home.

Two McKinneys, two kinds of emergency

In the older core, the emergencies are material-failure emergencies. Pre-war and mid-century housing near the square has cast-iron drain lines and sometimes galvanized supply pipe, both of which corrode from the inside. A cast-iron line that has narrowed and cracked backs up under ordinary use and brings in tree roots through the joints; galvanized supply pipe rusts shut until pressure collapses, and then a thinned section splits. These are pipes that have been quietly failing for years and finally stop.

West of US 75 and out toward Prosper, the housing is modern and the emergencies are fitting-failure emergencies. PEX and CPVC do not corrode, but a crimp ring that was never properly seated or a run of line that took UV damage during construction can let go abruptly - inside a wall, above a ceiling, with no warning at all. Add the ordinary wear-out of builder-grade angle stops and braided supply lines at the ten-to-fifteen-year mark and you have plenty of sudden water in a house that feels too new to have problems.

Both halves share the water heater. McKinney does not treat its own water: the city's Water Utilities division purchases wholesale treated water from the North Texas Municipal Water District, whose primary raw sources - as listed in McKinney's own annual water quality report - are Lavon Lake, Bois d'Arc Lake, Lake Texoma and Jim Chapman Lake, with Lake Tawakoni and the East Fork Water Reuse Project as additional supplies. NTMWD describes that treated water as moderately hard, and hardness is why McKinney water heaters start rumbling, lose capacity, and then fail earlier than the warranty sticker suggested.

  • Older core: a cast-iron drain line backing up sewage at the lowest fixture
  • Older core: galvanized supply pipe splitting at a thinned section
  • Newer west side: a PEX or CPVC fitting letting go inside a wall
  • Either: a scaled water heater splitting in a closet or garage
  • Either: a cracked hose bib or irrigation backflow assembly after a freeze

Finding your shut-off in a McKinney home

Which valve you are looking for depends on which McKinney you live in. In a newer home west of US 75, the main shut-off is normally on the incoming line in the garage, a utility area or an exterior wall, and homes plumbed with a PEX manifold often have labelled ports that let a plumber isolate one bathroom instead of the whole house. Find that manifold and photograph the labels.

In an older home near the square, expect the main to be at an exterior wall or in a crawl-space-era location, and expect the valve to be old. Try it today. A gate valve that has not moved in forty years is often seized, and the valve in the meter box near the street may be the only one that actually closes - which means buying a meter key, which costs a few dollars.

In both cases, label the shut-offs under sinks, behind toilets and at the water heater, and test them gently. A large share of emergencies become a wet towel instead of a wet floor because somebody already knew which valve to turn.

After a hard freeze in McKinney

A severe North Texas freeze hits both halves of McKinney, differently. In the older core, supply lines run through unheated attics, exterior walls and garages, and old hose bibs crack readily - a break there often leaks inside the wall once things thaw rather than visibly outside. In the newer subdivisions, the exposure is attic lines above second floors, pipes in garage walls, and the above-ground irrigation backflow assemblies Texas requires on in-ground sprinkler systems, which crack easily and can then run water continuously.

Before the cold, drip a faucet on the coldest exterior wall, open under-sink cabinets on outside walls, disconnect and drain hoses, cover the bibs, and confirm where your main shut-off is. If something splits, close the main first, then submit your request. After a region-wide freeze the licensed pros are working a long backlog across all of Collin County, and requests that went in early get seen first.

If water is coming down through a ceiling, cut power to that part of the house at the breaker before you go near it with a bucket.

How the McKinney referral works, and how fast

Dallas Best Plumber is a free referral service, not a plumbing company. We do not operate trucks, we do not hold a dispatch board, and we will not promise you an arrival window on another business's behalf. What we do is put your request in front of licensed, insured plumbers who take emergency calls in McKinney, with the details they need to call you back quickly. The form takes about two minutes, and the quote is theirs and free.

  1. 1. Tell us the problem

    Share what's happening, your ZIP code, and how urgent it is. It takes about two minutes — no phone tag.

  2. 2. We match you with a licensed local pro

    We connect you with a licensed, insured plumber who serves your area and handles your type of job.

  3. 3. They call you back with a free quote

    Your matched pro reaches out with a free, no-obligation quote. You decide whether to move forward.

Two things speed it up measurably. First, say whether the water is already off — a pro triaging several calls at 11pm treats a contained problem differently from an uncontained one. Second, include the age of the home and anything you already know about the system. After a region-wide freeze, when every licensed plumber in North Texas is working a backlog, an early and complete request is seen before a late and vague one.

Frequently asked questions

What should I do first in a McKinney plumbing emergency?

Shut off the water - at the fixture if the problem is local, at the main if it is not. If water is near outlets, panels or an electric water heater, kill power to that area at the breaker before going in. If you smell gas, leave the building and call your gas utility from outside. Then submit the form with your address, what is failing and how urgent it is.

Can you send an emergency plumber to McKinney right now?

We are a free referral service, not a plumbing company, so we do not dispatch trucks and we will not promise an arrival time on another business's behalf. What we do is put your request in front of licensed, insured local plumbers who handle emergency work in McKinney, with the details that let them call you back quickly. The form takes about two minutes.

Sewage is coming up at my lowest drain. What does that mean?

It means the blockage is in the main line rather than at one fixture, and water you use anywhere in the house has nowhere to go but out of the lowest opening. Stop using water entirely - no toilets, no washing machine, no dishwasher - and get matched. In McKinney's older core this is frequently a cast-iron line that has narrowed and cracked with root intrusion at the joints, which a camera inspection will show.

Where does McKinney's water come from?

McKinney does not treat its own water. The city's Water Utilities division purchases wholesale treated water from the North Texas Municipal Water District, which is delivered into the city's ground storage tanks. McKinney's annual water quality report lists the district's primary raw sources as Lavon Lake, Bois d'Arc Lake, Lake Texoma and Jim Chapman Lake, with Lake Tawakoni and the East Fork Water Reuse Project as additional supplies. NTMWD describes the treated water as moderately hard.

What will it cost?

We do not set prices and will not quote one - we are a free referral service and the plumber you are matched with gives the quote. The drivers are the hour, how much has to be opened up to reach the failure, and whether the fix is a part, a section of pipe or a longer run. Getting the water shut off before anyone arrives is the biggest single lever you have on the total.
