Emergency Plumber for Alcoa, TN Homes: Alcoa Water, Safe First Steps and ZIP Check
Alcoa sits right next to Maryville, but it runs its own water system. This page covers who to call about water, safe first steps and why the ZIP code comes first.
Alcoa Next Door to Maryville
Alcoa is about 2.1 miles from Maryville and shares a border with it. Many people searching for a plumber in Alcoa are close enough that the two towns blur together.
They are not the same, though. Alcoa is a separate city with its own water system, and a plumbing call has to be sorted by address.
Alcoa's ZIP code is not on our current coverage list, which is 37801, 37802, 37803 and 37804. Call with your address and ZIP code to find out whether a call there can be taken. If water is escaping, shut off the main valve first.

The City of Alcoa assumed ownership and operation of the water system on January 4, 1960. Its web page says the system serves more than 10,000 homes and businesses in Alcoa and northeast Blount County through more than 240 miles of water mains.
The City of Maryville buys water from Alcoa as needed, according to Alcoa's page and Maryville's own report. So a Maryville-area address may be on Alcoa water, and an Alcoa-area address may not follow Maryville's rules.

Alcoa and Maryville Street Boundaries Can Change House to House
Alcoa and Maryville meet along several streets. On a street where the boundary is close, the jurisdiction and the utility can change from one house to the next.
That is why every page on this site asks for your address and ZIP first. It is not a formality. It decides who serves you and which rules apply.
Permits Near the Boundary
We could not retrieve the City of Alcoa's current plumbing permit rules, so none are stated here. Ask the City whether the job needs a permit and who files it.
- A Maryville address is covered by the City of Maryville's permit office, not Alcoa's.
- Ask the plumber which office the permit goes to and how inspection is scheduled.
- Keep the paperwork with your house records.
Pressure Drops, Brown Water and Other Utility Calls
Not every water problem is plumbing. If the pressure drops across the street, or the water runs brown for a while, the cause is often in the utility's system.
- Ask a neighbor whether they see the same thing.
- Run the cold tap for a few minutes before assuming it is your pipes.
- Call the water utility, which can say whether there was flushing or a break.
- If it affects only your house, a plumber can check the valve and the pipe.
A call to the utility costs nothing and can save a visit. If only your house is affected, the water line page explains the checks a plumber runs.
A Leak Between the Meter and the House
On a water line that runs from the meter to the house, the leak is usually the homeowner's to repair. That pipe can run through a yard, under a driveway or beside a tree.
- Do the meter test.A moving meter with everything off means a leak.
- Close the house valve and retest.If the meter still moves, the leak is in the yard.
- Look for wet ground or green patches.They can mark the path of the line.
- Call the utility about where its pipe ends.Then call a plumber for the repair.
Digging calls for Tennessee 811, which asks for notice three to ten working days ahead. Ask who makes that call.
Know Your Valves Before Winter
Every house has a main shutoff, and many have a second valve near the meter. Find both now, label them and make sure they turn. A valve that is stuck cannot stop a flood.

- Exercise each valve gently once a year.
- Tell everyone in the house where the main is.
- Insulate exposed pipes and outdoor spigots before a hard freeze.
