The sewer key comes from your local water or sewer utility, not a hardware store

Your Schedule 1 sewer key — the T-shaped wrench that opens your sewer cleanout — is issued by the municipal water department, sewer district, or public works office that serves your address. You do not buy it retail. The utility either gives it to you when you request one, or sells it at cost, usually between $15 and $50 depending on the jurisdiction.

The process is straightforward: call your local sewer or water utility, tell them you need a Schedule 1 key for your property address, and ask whether they mail it, hold it for pickup, or require you to visit in person. Some utilities include the key with your first bill or when you open an account. Others keep them in stock at the office counter.

If you have recently moved into a home or are renting, the previous owner or landlord may have left the key behind — check the garage, basement, or utility closet before contacting the utility.

Key Takeaways

  • Contact your city or county water department or sewer district directly; they stock and distribute Schedule 1 keys for properties in their service area.
  • The key usually costs between $15 and $50, though some utilities provide the first one at no charge when you set up service.
  • You will need your street address and property account number (found on your water or sewer bill) to request one.
  • Pickup or mailing typically takes one to two weeks; some utilities keep keys in stock for same-day or next-day pickup at their office.

How to contact your local water or sewer utility

Start by finding your water bill or sewer bill — it will list the utility name and a customer service phone number. Call that number and ask for the department that handles sewer access keys or cleanout tools. You may be transferred to a field services, maintenance, or customer service department depending on the utility's structure.

If you cannot locate a bill, search online for "[your city name] water department" or "[your county name] sewer district." Most utilities have a website with a phone number and sometimes an online form to request tools or information. A few larger cities allow you to order a key through their website and pick it up at a designated office location.

Have your street address and house number ready when you call. Some utilities also ask for your account number, which appears on your bill.

What to expect when you request a key

Most utilities will ask you to confirm your address and verify that you own or rent the property. Some require proof of residency — a utility bill in your name or a lease — before they hand over the key. This is standard practice to prevent unauthorized access to sewer lines.

The utility will tell you the cost (if any), how long it takes to receive the key, and whether you can pick it up or if they will mail it. Mailing usually takes five to ten business days. Pickup at the utility office is often available within one to three business days.

If your utility does not stock Schedule 1 keys

A small number of utilities do not distribute keys directly. In those cases, ask whether they can recommend a plumbing supply company or hardware store in your area that stocks Schedule 1 keys. Some independent plumbing suppliers carry them and will sell to homeowners without a contractor license.

You can also order a Schedule 1 key online from plumbing supply retailers, though you will pay more than the utility's cost — typically $25 to $60 plus shipping. This route is slower but works if your utility is unresponsive or does not stock keys.

Replacing a lost or damaged key

If you have lost your key or it is bent or broken, contact your utility again and request a replacement. Most utilities replace lost keys at no additional charge or for a small fee. Tell them the original key is missing so they know to issue a new one rather than look up your account history.

Keep your key in a safe, accessible place — many homeowners store it in a labeled container near the cleanout or in a garage cabinet. A lost key is inconvenient but not permanent; the utility will always issue another one.

Understanding your utility's service area

If you live in an unincorporated area or a small town, your sewer system may be run by the county rather than the city. Check your sewer bill to see which agency is listed as the provider. Some rural areas use septic systems instead of municipal sewers, in which case you would not need a Schedule 1 key — your septic tank access is typically a buried lid on your property that you can open with a shovel or pry bar.

If you are unsure whether your property is on a municipal sewer line or a septic system, call your local health department or building department. They can tell you in one call and direct you to the right agency for a sewer key if needed.

Frequently Asked Questions

Can I use a regular wrench instead of a Schedule 1 key?

No. A Schedule 1 key is designed to fit the specific square or T-shaped opening on your sewer cleanout. A regular wrench will not fit and may damage the cleanout fitting. Always use the correct tool.

Do I need a key if I rent my home?

Your landlord is responsible for maintaining the sewer line, so they should have the key. Ask them for it or ask them to contact the utility to request one. If they refuse or are unresponsive, you can contact the utility yourself and explain that you are a tenant; some utilities will issue a key to tenants for emergency access.

What if the utility says I cannot have a key?

This is rare but can happen if the utility has security concerns or if the cleanout is in a public right-of-way rather than on your property. Ask why and whether there is an alternative — some utilities will send a technician to open the cleanout for you instead of issuing a key.

How much does a Schedule 1 key cost?

Cost varies by utility. Most charge between $15 and $50, though some provide the first key free when you open an account or request one for the first time. Call your utility to ask about their specific pricing.

Can I order a Schedule 1 key online from the utility?

Some larger utilities allow online ordering through their website, but most require a phone call or in-person visit. Check your utility's website first; if there is no online option, call customer service.
