What is hubless pipe?
Hubless pipe and fittings are also referred to in the plumbing industry as no-hub. Hubless cast iron soil pipe and fittings are manufactured without a hub, in compliance with CISPI 301.
What is used to join the ends of to hubless cast iron pipes?
Hubless Joints Hubless cast iron soil pipe is joined by using the hubless coupling. Several different types of hubless couplings are available.
What is aspiration plumbing?
Aspiration: The result of mixing air with discharging water for the purpose of enhancing the hydro-massage effect of the whirlpool.
What type of pipe fitting inserted to one pipe and allow to screw another smaller pipe?
Bushing Fittings – Bushings, sometimes called reducer bushings, are used for connecting two pipes of different sizes. The larger diameter of the bushing fits inside of the larger pipe. The smaller pipe is then inserted into the smaller end of the bushing.
What is a hubless 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 pipe Siphonage?
Siphonage is a the emptying of the liquid in a container through a tube to another container that is placed in a lower position. An example of siphonage is when you empty the gas out of a gas tank in a car through a tube into a gas can that is sitting on the road.
What is anti Siphonage pipe?
An extra pipe connected to the outlets of toilet seats of all the floors, the other end of which is exposed to atmosphere is called anti-siphonage pipe. These are provided to maintain water seal so that foul gases of the sewer line do not find entry in to the toilet/ bathrooms.
How do you connect non threaded galvanized pipe to PEX?
Insert one end of the non-threaded galvanized pipe into the coupling. Align the coupling end with the drawn line on the pipe. Insert the second pipe into the coupling and center the coupling between the two drawn lines.
What is SV pipe?
SV piping and fittings are manufactured for a system above ground, and the fittings are cast for horizontal and vertical installations to provide the correct gradient on the slope as required from SANS 10252-2.
Why is it called cast iron soil pipe?
Cast iron pipe is pipe made predominantly from gray cast iron. It was historically used as a pressure pipe for transmission of water, gas and sewage, and as a water drainage pipe during the 17th, 18th, 19th and 20th centuries.
What is hub and spigot?
The end connection of a fitting that is to be assembled into another fitting is called the “Spigot.” The spigot end of a fitting has the same outside diameter as pipe. The common female connection of PVC fittings is referred to as the socket or hub, and the spigot end of a fitting can be inserted into a Hub or Socket.
What is self siphonage and induced siphonage?
Self-siphonage – atmospheric pressure causing water seal to be sucked out of trap. Induced siphonage – atmospheric pressure plus appliance causing water seal to be sucked out. Compression – water discharging from above combines with bend in system to create positive pressure.
What is meant by back siphonage?
Back-siphonage is backflow caused by negative pressure (i.e. vacuum or partial vacuum) in a public water system or customer’s potable water system. The effect is similar to drinking water through a straw.
What does Siphonage mean?
Siphonage definition Siphonage is a the emptying of the liquid in a container through a tube to another container that is placed in a lower position. An example of siphonage is when you empty the gas out of a gas tank in a car through a tube into a gas can that is sitting on the road.
What is anti Siphonage effect?
It incorporates a valve that lets air into the hose to break the siphon effect when water stops flowing, and that keeps flowing water from spilling out of the hose. (Anti-siphon valve assemblies are sometimes referred to as “vented loops” because the valve is typically in a pipe assembly in a loop of hose.)
