Violation 2 Unvented traps, Traps and vents are among the most misunderstood concepts in plumbing The primary function of both is. to maintain a sanitary barrier between living spaces and the sewage system Without a trap to seal off. plumbing fixtures nasty things such as explosive methane gas and vermin can creep into the house Without. proper venting water in the trap can be siphoned out leaving the trap dry and useless. Violation 3 Flat venting, All the various methods for venting a trap break down into two categories wet and dry A wet vent is an oversize. drain pipe that also serves as a vent A dry vent is a pipe whose only function is to provide air to the system Either. type will fail if it fills up but wet vents are kept clear by wastewater washing downstream Water that washes into. an improperly installed dry vent however can become trapped along with whatever. sediment it may be carrying,Violation 4 Horizontal vent below flood rim. Any portion of a vent that is below the flood rim of a fixture must be able to. drain after it becomes flooded by a clogged drain,Violation 5 Violation 6 Inaccessible clean outs. Inadequate clean outs It may sound obvious but a clean out that a plumber can t get to. No matter how well designed or carefully installed they are isn t much good Adequate clearance must be maintained to permit. drains can still become clogged Access for cleaning them service people to access clean outs and also have room to work. out must be provided in specific locations which vary. depending on which code is in force,Where clean outs are required UPC 707.

Clean outs in concealed piping or underfloor piping with less. Clean outs are required for any horizontal change of than 24 in vertical clearance must be extended above floor or. direction exceeding 135 see plan view below to outside of building. One eighth,Violation 7 Inadequate air gaps, To ensure that wastewater cannot be siphoned back into fresh water. lines a minimum air gap must be maintained between water spouts. and basin flood lines This violation can occur when tubs are built. A clean out is required on site or when imported fixtures are used with domestic sinks But. because this angle the most common violation is a hand sprayer that does not contain. 45 exceeds 135 a vacuum breaker or automatic antisiphon valve. 45 45 45 45 180,Where clean outs are not required,Above the first floor.
Branches 72 or less from the vertical one fifth bend. Horizontal branches shorter than 5 ft long unless branch serves. kitchen sink,Where clean outs are required IPC 708. Horizontal branches not more At the base of each stack. than 100 ft apart Within 10 ft of connection be, Horizontal change of direction tween building drain and sewer. exceeding 45 if more than one P trap connections with slip. change of direction in a run of joints can be used as clean outs. pipe only one clean out every as long as they are not more. 40 ft required than one pipe size smaller than,the drain size. Violation 8 Inadequate Violation 9 Pressure and temperature relief of water heaters. space around toilets improperly installed,and basins If it had no protective device. Enough space must be provided so that a domestic water heater. large people can use toilets and basins whose thermostat failed. without discomfort clearances listed would see a continuous rise. below are minimums in temperature and pressure,When the pressure exceeded.
the capacity of the tank 300,psi the tank would burst. expelling superheated water,and shrapnel with explosive. force To prevent such,catastrophic failures water,heaters are required to be. protected against both,extreme temperature and,extreme pressure This is. most often done with an,integral temperature and,pressure relief valve which is.
designed to open if either,condition becomes,dangerously high. Violation 10 Inadequate combustion air,Gas burning and oil. burning appliances require,a specific volume of,airflow for safe. combustion Restricted,airflow can cause,incomplete combustion. and poor drafting of,exhaust gases When this,happens energy is wasted.
the life of the appliance is,shortened and the lives of. the house s inhabitants are,endangered I most,frequently encounter this. violation during a,basement remodeling,project when a furnace or. water heater has been,enclosed in a small,mechanical room with no. provision for makeup air,Supplying combustion air,can be as simple as placing.
a vent in the wall or as,complicated as running,multiple fresh air ducts to. each appliance In this,area it s wise to consult,with the appliance. manufacturer in addition,to the local building,SEE ERRATA AT END OF ARTICLE. Erratum Combustion,appliances require two,sources of combustion air. Ironically we made a mistake in a drawing,for Redwood Kardon s article Ten Com.
mon Plumbing Mistakes FHB 126,pp 70 73 The bottom drawing on p 73. should have included an upper combus,tion air source in addition to the lower. combustion air supply shown According,to code the upper combustion air source. must be located within the top 12 in of the,room ducted to the outside and protected. plumbing fixtures nasty things such as explosive methane gas and vermin can creep into the house Without proper venting water in the trap can be siphoned out leaving the trap dry and useless Violation 3 Flat venting All the various methods for venting a trap break down into two categories wet and dry A wet vent is an oversize drain pipe that also serves as a vent A dry vent is a pipe
