Can you use no hub cast iron underground?
A: Hubless cast iron soil pipe and fittings are allowed for underground installations by all of the model codes.
What’s a no hub coupling?
Intended for use with DWV systems, no-hub couplings are used to join cast iron soil pipe that does not have the traditional Hub and Spigot. They are normally installed using a torque wrench. Generally, they have more clamps and provide a greater band load than standard no-hub couplings.
What is a no-hub coupling used for?
Is cast iron better than PVC?
Cast iron is thick and dense. Water flowing through it won’t cause as much vibration as it would in a PVC pipe. These vibrations are what lead to noise, so if sound dampening is a major concern, cast iron is the better choice.
Can I bury no-hub coupling?
Mission and husky couplings are allowed underground here, no hubs aswell. Have to fasten to 60ibs.
Can you use a sanitary tee on its back?
When you are using a sanitary tee, you should not lay it on its back with a side opening because this will result in an upstream splash of waste when it hits the bottom of the horizontal pipe. This will create clogging inside the line.
Can I use sanitary tee horizontal?
Sanitary tees may only be used on drainage piping when transitioning from horizontal (1/4” per foot) to vertical. All others must sweep in direction of flow with proper drainage fittings.
What does no hub outlet mean?
This type of outlet is the opposite of the hub outlet. SPIGOT OUTLET (NO HUB OUTLET): Male, pipe size, plain end connection for caulking into a soil pipe hub or joining to plain end pipe with a mechanical coupling.
What kind of piping is cast iron used for?
Cast Iron is the premier piping material for sanitary and storm drain, waste and vent applications. It has been used in these applications for hundreds of years and is for non-pressure applications where temperatures will not exceed 212° F. It is the most durable DWV piping system available and can be used in all types of construction.
What are no hub pipe and fittings used for?
No-Hub Pipe & Fittings. Scope: This specification covers hubless cast iron pipe and fittings used in sanitary drain, waste, and vent (DWV), sewer, and storm drainage applications. This system is intended for use in nonpressure applications.
What is the scope of the cast iron standard?
Scope: The purpose of this standard is to establish standards covering material, dimensions, and tolerance for pipe and fittings for hubless cast iron sanitary and storm drain, sanitary waste, and vent piping applications. Cast Iron is the premier piping material for sanitary and storm drain, waste and vent applications.
