Water Heater

Which of the following is not considered as Plumbing Appurtenance?

• Water Tanks

• Water Pumps

• Water Meter

• Water Heater

uPVC

It is a pipe most commonly used for cold water supply lines. It is made rigid by the omission of plasticizers.

cPVC

It is a pipe more flexible and can withstand higher temperatures.

PPR

It is widely used in high pressure cold and hot water plumbing and water supply systems, which ensures the plumbing to have a perfect seal tight system.

HDPE

Is a thermoplastic made from high density polyethylene with high level of impermeability and strong molecular bond, making it suitable for high pressure pipelines and industrial applications

Unplasticized Polyvinyl Chloride

What does uPVC stand for?

Polypropylene Random

What does PPR stand for?

High Density Polyethylene

What does HDPE stand for?

Type K

It is the heaviest and thickest copper that is suitable for underground & main.

Nipple

Bushing

It is a pipe fitting which is threaded on both the inside and the outside and used to reduce the size of the pipe opening to receive a pipe or fitting of a different size.

Check Valve

Soldering

It is a pipe joining method that is used in used in copper or brass pipes

Rotary Pipe Cutter

It is a pipe cutting tool that is used for pipes with a large diameter.

Hacksaw

It is a pipe cutting tool that is used for metal or plastic pipes of smaller diameter

Foot Valve

It is a non-return valve installed in a pump suction or at the bottom of pipelines to prevent water from flowing backward when the pump is off.

Float Valve

An automatic valve whose opening and closing are controlled by a float at the end of a lever.

Plumbing Appliance

Any one of a special class of device or equipment intended to perform a special plumbing function. Its operation and/or control may be dependent upon one or more energized components, such as motors, controls, heating elements and pressure-temperature sensing elements.

Plumbing Fixtures

These are approved-type installed receptacles, devices or appliances supplied with water or receive liquid or liquid-borne wastes and discharge such wastes into the drainage system to which they may be directly or indirectly connected.

Reverse Osmosis

It is the movement of liquid through a semipermeable membrane from a more concentrated solution to a more dilute solution. This is achieved by applying an external pressure to the solution on the more concentrated side of the membrane.
