A-Z About Water Primary Connection

by - November 19, 2021

Water main connection means the connection between our homes to the main water supply. This critical system component's function is to transport water. Working with water mains can be a time-consuming and complicated process for inexperienced plumbers. On the other hand, Local Plumbing and Sewer's plumbers are experts in all aspects of water primary integration, installation, and repair. If you want to know more about water main connection in detail, continue reading this article.

Water Main Connections

Types of Materials used in Water Connections:

Water main connections are made of a variety of materials.

These are some examples:

  • Ductile steel pipe
  • PVC (Polyvinyl Chloride)
  • Steel Concrete Cylinder
  • Polyethylene (Plastic)

Water main connection installation

  • Excavated to the depth specified on the drawings with a minimum of two covers.
  • Class "B" Pipe Bedding Materials are available in -150 mm,300 mm,400 mm, 500 mm,1000 mm,1500 mm, which should be used.
  • Tape (Marker)  

Pipe Protection

  • Caps keep debris out of pipes during transportation and are required on all pipes.
  • They are required on both the bell and spigot ends of the pipe, resulting in a lower risk of contamination.

Pipe Assembly

  • When the pipe is laid in a trench at design, grade, and assembled with a come-along or pry bar, there is a risk of pushing the pipe into the bell too far and damaging the bell.
  • On the PVC pipe, there is a line indicating the required insertion depth of the pipe.

Thrust Blocks

  • Must be installed at specified locations such as bends, tees, valves, reducers, and end caps. Specification drawings
  • Mechanical joint restraints are an alternative to thrust blocks.
  • Joint restraints location must be determined by the design of the engineer who came for installation. Typically, the fitting is restrained along with several lengths of pipe on either side of the fitting.
  • There are two kinds of restraints:

(1)Megalug or Megaholder Restraining Gland Ring

(2)Joint Restraint Restraining

Air and Vacuum release

  • A water distribution system's design must recognize the importance of removing air from the system and breaking a vacuum if one forms.
  • These conditions typically occur when a water main is ruptured.
  • Being filled or drained in preparation for planned maintenance or during emergencies.
  • Air release can be accomplished in 2 to 3 ways:

(1)Putting in a fire hydrant at the highest point.

(2)Installing a water supply at the highest point.

(3)Placing an Air Release valve at the highest point.

Water Main Connections

Service Connection Ductile Iron

  • Direct tapping is permitted up to a diameter of 25 mm.
  • Services with a diameter greater than 25 mm necessitate the use of a service saddle.
  • Service connections should be at least 1 meter apart from adjacent services, pipe bells, or fittings.
  • A direct tap was completed with a drill and a tap bit.
  • Shell cutter bit was used to complete the tap connection through the service saddle.

Service connection PVC

  • Direct tapping is possible but not recommended.
  • For new construction, 

use a tapping tee.

  • Tapping will be finished with a service saddle.
  • Service connections should be at least 1 meter apart from adjacent services, pipe bells, or fittings.
  • The tap connection through the service saddle was completed with a shell cutter bit.

Pressure Test 

  • The new water main was tested at 150 percent of its normal operating pressure.
  • Each pipe section was gradually filled with the expulsion of water and air tested.

Leakage Test 

  • Held concurrently with the Pressure test.
  • Count the amount of water required to keep the pressure up.
  • Must not be greater than the calculated value.

Conclusion:

If you are going to change your home, then you must need some information regarding the water main connection. If you want to know enough about the water main connection, here is the article which can help you.
