What is a plumbing system?
Plumbing includes all the piping and fixtures that provide water for drinking, cooking, bathing, and laundry; as well as a means of disposing of wastewater. (Yuck!)
-
Putting in a plumbing system takes a lot of thought.
When a house is being built, plumbers and carpenters must work together so the
frame of the house is prepared for plumbing to be put in.
-
Plumbing can be dangerous, so there are codes that must be followed in order to keep everyone safe.
A code is a set of rules that can be enforced by law!!!
-
Some Common Colds Codes
1. UPC (Uniform Plumbing Code)2. BOCA (Basic Builders Code)3. IBOC (International Conference of Building
Officials)4. NPC (National Plumbing Code)5. SPCCI (Standard Plumbing Code)
**Local codes usually adopt all or parts of the UPC or other plumbing codes. Once adopted, codes can be enforced by law!!
-
In the plumbing business, errors cost money, so you better know your stuff!!!
-
There are 2 Types of Plumbing Systems
1) Water Supply System
2) Drainage, Waste, and Venting (DWV)
-
Water Supply System
Distributes water under pressure throughout the structure for drinking, bathing, cooking, and laundry.
This is a 2 pipe system.
One pipe carries cold water, and the other hot water.
-
DWV
Carries away wastewater and solid waste from bathrooms, kitchens, and laundries.
This subsystem is not under pressure, and must be properly vented to prevent wastewater form entering the drinking water supply.
-
What is the difference between a valve, a fixture, and a faucet?
-
Valves
Devices that control the flow of water in the water supply system.
They are installed at certain places on the lines so that water can be shut off easily.
-
Faucets
Valves that permit controlled amounts of water as needed for use in a building.
They deliver water to sinks, showers, and bathtubs, but can also deliver water to a hose or bucket.
-
Fixtures
Water-using devices such as sinks, bathtubs, urinals, stools, or showers.
They are attached to the plumbing system and receive water from the supply system.
-

Compression Fittings (COMP)
Compression fittings use a nut and olive (copper, brass or rubber compression ring) to make a water tight seal between the fitting and the pipe. All pipes used must be clean and free from burrs before assembly. A suitable sealing paste should also be applied before the joints are tightened using a wrench or spanner. Do not over tighten as this can lead to problems should the fitting need to be removed

Speed Fit, HEP2O, Copper/Brass Push Fit
There are many different types of push fit joints are now being marketed, they're available in plastic, brass & copper. There's not much difference between them, they all incorporate some form of grip ring which creates a seal between the pipe and the fitting and prevents the pipe from pulling out. All pipes used must be clean and free from burrs before assembly. Insert the cleaned pipe into the fitting and push into place by hand.

Fitting Sizes
Fittings are supplied in a variety of sizes ranging from 6mm through to what ever size you require, although larger size fittings may have to be specially ordered.
Generally the average plumber working in domestic properties will come into contact with fittings ranging from 6mm to 28mm.
As a plumber you will continue to come into contact with fittings still measured in old imperial (inches). Some merchants catalogues will have fittings still measured in inches especially internally or externally threaded fittings as these are to BSP (British Standard Pipe).
1/2 = 12.7 mm 3/4 = 19.05mm 1 = 25.4 mm
COMMON PLUMBING FITTINGS

Ordering Fittings 1
Ordering couplers is straight forward as they are the same size at both ends (eg 15mm coupler) Ordering tees is slightly more complicated. State the largest size first then the opposite side and then the centre size (eg 22mm x 15mm x 22mm or 22mm x 22mm x15mm see examples below)

All drains can become clogged.
It is important to know different ways to unclog a drain so that you may avoid overflows or future problems!!
-
For a slow drain.
Use chemical cleaners, such as Drano to solve the problem.
Be careful, these kind of chemicals are dangerous and can make you very sick or even kill you if they are not used properly!

FIRE SPRINKLER SYSTEM
A fire sprinkler system is an integrated system of underground and overhead piping, with one or more automatic water supplies, to which fire sprinklers are attached in a systematic pattern
-
Automatic / Sprinkler System
There are two general types of Automatic Sprinkler Systems: the Automatic Wet and Automatic Dry
FIRE PROTECTION SYSTEMS
-
TYPES OF SPRINKLER SYSTEMS
Wet-Pipe Sprinkler Systems
Dry-Pipe Sprinkler Systems
Deluge Sprinkler Systems
Pre-Action Sprinkler Systems
-
Wet-Pipe Sprinkler Systems
are installed more often than all other types of fire sprinkler systems
Operation: When an automatic sprinkler is exposed to sufficient heat, the heat sensitive element (glass bulb or fusible link) releases, allowing water to flow from that sprinkler. Sprinklers are manufactured to react to a specific range of temperatures. Only sprinklers subjected to a temperature at or above their specific temperature rating will operate.
-
Dry-Pipe Sprinkler Systems
are second most common sprinkler system type Operation: When one or more of the automatic
sprinklers is exposed to sufficient heat, it opens, allowing the maintenance air to vent from the sprinkler. Each sprinkler operates individually. As their air pressure in the piping drops, the pressure differential across the dry pipe valve changes, allowing water to enter the piping system. Water flow from sprinklers needed to control the fire is delayed until the air is vented from the sprinklers.
-
Deluge Sprinkler Systems
are system that have open sprinklers, i.e. the heat sensing operating element is removed during installation, so that all sprinklers connected to the water piping system are open. These systems are used for special hazards where rapid fire spread is a concern, as they provide a simultaneous application of water over the entire hazard
-
Deluge Sprinkler Systems
Operation: Activation of a fire alarm initiating device, or a manual pull station, signals the fire alarm panel, which in turn signals the deluge valve to open, allowing water to enter the piping system. Water flows from all sprinklers simultaneously.
-
Pre-Action Sprinkler Systems
similar to deluge sprinkler system except that automatic sprinklers are used, rather than open sprinklers
-
COMPONENTS OF FIRE SPRINKLER SYSTEM
Fire Sprinkler is a nozzle which distributes water in a specific spray pattern.
Automatic Sprinkler is a fire sprinkler with a normally closed nozzle which can be
individually opened by heat, by either melting a fusible element or rupturing a liquid-filled glass bulb.
Main is a principal artery of a system of continuous piping to which branch
lines are connected.
Branch line a part of the piping to which fire sprinklers are connected.
Riser is a water main which extends vertically one full storey or more to
convey water to individual floor mains and branch lines.

Gas Piping & Shut-Off Valves
Piping should be adequately supported to the well, beyond the reach of people passing by.
When pipes pass thru floors, walls or partitions, no joints should be allowed at these places to minimize danger of leaks.
Piping should not be run in or through elevator shafts, air or ventilation ducts, chimneys or flues.
Ends of piping should not be plugged with cork, wood, paper, etc., the correct terminal fitting should be used.
Suitable gas line shut-off valve should be fitted for every appliance.
Both ends of the connection to portable appliances should be securely attached by means of clips. Hose should be of a type resistant to LP gas.
LIQUEFIED PETROLEUM GAS
-
Location of Appliance
The location of the gas appliance in the kitchen should be decided before the piping is laid out. Appliances should be set where conditions for ventilations and air circulation are met.
A permanent and adequate air supply should be provided for the appliance. This source of air for combustion and ventilation should not be subject to accidental interruption or curtailment.
Appliance should be installed in a way to allow ease of repair and adjustment of appliance burners and parts
A water heater should be installed in a place with adequate ventilation and with a sufficient clearance between ceiling and top of heater.
LIQUEFIED PETROLEUM GAS
-
Testing for Leaks
Before any system of gas piping is finally put into service, it should be carefully tested to ensure that it is gastight. Where any part of the system is to be enclosed or concealed, this test should precede the work of closing in.
Matches, candles, or other sources of ignition should not be used to check for gas leakage. The position of a leak may be detected by using soap solution.
Leaking or otherwise defective pipes or fittings should be replaced. No attempt should be made to affect temporary repair.
