Backflow Preventer Permits 

SPRWS requires plumbing contractors obtain a plumbing permit before installing or replacing a backflow preventer. Only a person licensed by the Minnesota Department of Labor and Industry as a journeyman plumber may lawfully install, replace or rebuild backflow preventers; such person must also have a Certificate of Competency as a plumber/gasfitter issued by the City of Saint Paul Department of Safety and Inspections.

Annual Testing Requirements

Documentation Requirements

To ensure the safety of public health and comply with code requirements, SPRWS requires annual submittal of complete documented test results on its Reduced Pressure Backflow Preventer Test Report or Testable Double Checks Form.

Failure to provide this annually required documentation is a code violation and may result in discontinuation of water service.

Tester Qualifications

Only a person licensed by the Minnesota Department of Labor and Industry as a “backflow preventer tester” may perform backflow preventer tests.

Filing Fees

No permit is required for testing or rebuilding a backflow preventer, however a filing fee does apply (currently $35.00 per device).

Method of Payment

The plumber is not responsible for paying the testing fee beginning on January 1, 2018. The $35 testing fee will be applied to the customer's water bill.

Codes

Minnesota State Plumbing Code Section 4714.0603.5.23 as well as Saint Paul Legislative Code Section 94.18 require annual testing of reduced pressure zone (RPZ) assemblies and testable double check valve assemblies.

Emergency Plumbing Work 

Work requiring a plumbing permit and inspection that is performed on an emergency basis is exempt from obtaining a plumbing permit prior to the commencement of work. However, a plumbing permit must be obtained within 24 hours (weekends and holidays excluded), from the time of inspection or a double fee will be applied.

Hydrant Permits 

Hydrant Permits

Permits are required to operate water hydrants for construction use. As needs for each use vary, as do locations, size, and other options, if you require a permit to operate a hydrant, you will need to talk to someone at the engineering service desk to help determine the best fit for your needs. The engineering service desk can be reached at 651-266-6270 from 7:30 am - 4:00 pm (Monday – Friday).

Once you have a permit to use a water hydrant, it is essential to operate the hydrant properly. Failure to operate the hydrant properly can result in damage to the water mains near the hydrant. Operating a hydrant without a permit is against the law and subject to a fine of $1,000. Fire departments and other city departments also have the need to operate water hydrants as required by their work. It is essential for these personnel to operate the hydrants safely as well, to prevent damage to the water mains.

Operating Hydrants

This video demonstrates the proper procedure for opening and closing a fire hydrant safely and effectively.

Steps for Operating a Hydrant

1. Prep the ground so you don’t do damage
2. Remove the cap from where you are going to attach your diffuser or other attachment.
3. Attach a diffuser or other attachment for dispersing the water. Be sure the other caps on the hydrant are closed.
4. Open the hydrant clockwise.
   • For non-pacer hydrants - open a minimum of four turns and no more than eight turns. Some older hydrants may ‘chatter’ – if so, continue to open to a maximum of eight turns.
   • Pacer hydrants can be opened all the way.
   • If you are not sure of the difference, do not open more than eight turns.
5. When finished, close the hydrant, turning the wrench counter-clockwise VERY SLOWLY. This means turn the last few turns at a rate of 20 seconds per turn. If you fail to close the valve slowly, it could create a water hammer in the system. A water hammer can cause main breaks.
6. Use the hydrant to turn off the water. Do not turn off the water using a ball valve attached to the meter assembly.
7. After closing the hydrant, be sure the water in the hydrant is wasting—the water needs to drain out completely before you put the cap back on the hydrant.
