INTD 59 bathroom plumbing & fixtures
2
plumbing residential plumbing system provides water to various points throughout the home—understanding how water is supplied & distributed is necessary a balance must be met between design criteria & economic considerations residential plumbing system is made up of three basic systems: supply system drain & waste system vent system

supply system brings pressurized water from utility main or well distributes water to appliances & fixtures on demand a valve regulates the flow: faucet handles & lever controls, shower & tub controls, ball-rocker valves in the laundry, pressure-relief valves on water heaters water pressure to the house must be established prior to the design plumber must check water pressure available to ensure correct balance between supply & demand

drain & waste system transports gray water (used water from washer, dishwasher, sinks & bathing) and waste from house to sewer or septic tank most fixtures drain by gravity—toilet uses gravity & falling water (some low-flow use injection of air as well) backflow must be considered in fixture design designer must be aware of plumbing drain cleanout locations

8
vent system exhausts noxious sewer gases from house also maintains air pressure in drain system, helping waste to flow down to sewer plumbing system is a simple application of supply and demand— utility main or private well supplies water to house on demand drain-waste and vent systems extract noxious fumes & wastes from house on demand
9
plumbing codes codes vary from region to region the size of the main supply line to house & the supply lines to individual fixtures/appliances depends upon: number of fixtures to be installed water pressure delivered by utility or well (typically 46-60 lbs. per square inch) elevation of fixture from water source
10
plumbing codes supply lines from main supply typically ¾-1 inch in diameter many suppliers specify the size of a supply line for proper installation of a fixture plumber is responsible for calculating pipe size in compliance with applicable code designer MUST communicate with plumber early in design process collaborate so that local code is met & water pressure is appropriate
11
bathtubs so many sizes & shapes—no longer an “average” most state laws require a slip-resistant bottom— handle on one side also very helpful safety feature may be ordered with: left or right drain all four sides enclosed front & two sides enclosed front & one side enclosed drop in model—sunken model
12
bathtubs cleaning? children?
13
bathtubs manufactured of several materials: porcelain enameled cast-iron most durable—very expensive & HEAVY floor should be strong enough—tub+water+body porcelain can chip—offers color choices retains heat very well porcelain enameled formed steel acrylic-reinforced fiberglass
14
bathtubs manufactured of several materials: porcelain enameled cast-iron porcelain enameled formed steel lighterweight— 100 lbs —upper story installations less expensive noisier—can use coating or insulation may flex—have thinner layer of insulation acrylic-reinforced fiberglass
15
bathtubs manufactured of several materials: porcelain enameled cast-iron porcelain enameled formed steel acrylic-reinforced fiberglass easy maintenance lightweight not as durable as cast-iron or steel tub surround can be cast as one piece—can also include accessories
16
jacuzzi synonymous with whirlpool baths—jets create circular pattern of bubbles providing massage made of continuous cast acrylic, reinforced with fiberglass
17
bathtub surrounds may be reinforced fiberglass, decorative laminate, ceramic tile, stone…options are endless failure to install & caulk correctly is major cause of leaks access to plumbing for future repairs?

showers minimum requirements for stall shower: 34-in square standard height of shower head: 66-in for men 60-in for women install at 74-inches & adjust for height handheld shower offers additional flexibility
23
showers shower heads more than 5-10 years old use 3-8 gallons of water per minute—2.4 gallons per minute saves almost 12,000 gallons water per year
24
showers
28
several ways to keep water within the shower area: shower curtain—water can escape glass shower door—soap & hard water residue walls with no door—generally master bath
29
showers wheelchair accessible showers
30
faucets deck mounted—used only for tubs wall mounted—used for showers; tub/shower combo both available in single or dual control—single control regulate temperature more easily
31
lavatories come in many sizes, shapes & materials according to personal preferences & space requirements materials: vitreous china glass cast iron stainless steel sculpted marble usually round or oval—can be whatever you dream china ceramic enameled steel polished brass solid-surface
32
lavatories
36
lavatories pedestal
37
lavatories self-rimming
38
lavatories under the counter
39
lavatories wall mounted
40
lavatories flush
41
lavatories above surface
42
lavatory faucets single-handle center-fit spread-fit
43
lavatory faucets placement depends upon design of sink water conservation laws mandate flow requirements finishes: polished chrome black chrome polished brass—needs some sort of clear coat gold plated brushed nickel copper—needs some sort of clear coat finish
44
lavatory faucets accessibilty
45
toilets toilet = water closet made of vitreous china—withstands acids may be: wall-hung—flush through wall drain floor-mounted—flush through floor or wall drain
46
toilets low profile
47
toilets gravity flush all required to have visible water turn-off near bowl
48
toilets pressure assisted: From the outside, pressure assisted toilets look identical to gravity toilets. When you lift the lid of a pressure assisted toilet, however, instead of seeing water, you will notice an inner tank. The inner tank is completely sealed; when water is fed from the water line, the air inside the tank gets compressed. When the toilet is flushed, instead of just falling by the force of gravity, the water is forced out with the pressure of the compressed air. This pressurized stream of water cleans all the waste from the bowl much more efficiently than the water from gravity toilets. The pressure in the toilet is therefore created by using the water pressure provided by the water company - no pumps or other devices are used.water pressure

toilets pressure assisted:
50
toilets dual flush options— uses more water for solid waste removal
51
bidets generally installed as a companion to a toilet used for cleansing the perineal area—sit astride the bowl facing the controls
