Are black steel gas pipes threaded? - ANS--sure
-there ought to be three/four to one inch threaded on every give up
Are domestic inspectors required to investigate wells? - ANS-Yes, home inspectors are required

408) - ANS-Answer:
- Yes
Are the prohibited traps a reportable deficiency? (P. 426) - ANS-No, whilst these are no longer
allowed in more recent houses, those traps are not necessarily deficient in an older domestic.
Note:
- tell patron approximately presence of prohibited lure and give an explanation for capacity
problems
Because of the flammable vapor ignition resistant requirement of 2003, what factors limits
inspection of a gas water heater? - ANS-Answer:
Combustion chamber inspection is restricted to a small view port.
Because removing an abandoned oil storage tank is so high priced, what should domestic
inspectors do when they're common in his or her vicinity? (P. 452) - ANS-Answer:
,- disclaim inspection for underground oil tank
- propose evaluation by contractor w/special device to positioned tanks
Bend radius for CSST? - ANS--3 inches for 3/4 inch and smaller
-5 inches for 1 inch and longer
Black metallic fuel pipe, common dimensions? - ANS--normally is available in 10 foot sections
-1/four inch increments among 1/2 and 1 1/2 inches
-must be as a minimum agenda 40
Can a CSST be related to portable home equipment including a garments dryer? - ANS--nope
-the csst have to be mounted to a steady fitting, and a FAC have to be used to attach an
equipment to the suitable
Can CSST enter appliance shelves and into fireplaces? - ANS--sure, however all valves and
fittings inclusive of sediment traps have to be established as advocated
Can drain, waste, & vent pipes (DWV) be contracted? (P. 412) - ANS-No, DWV pipes can not be
shriveled in course of float.
Can fuel pipe be established in concrete/stable floors? - ANS--ought to be installed in a sleeve
such as a PVC pipe
-if it terminates outdoor, it ought to be sealed where the sleeve penetrates the foundation interior
and the sleeve ought to be ventilated outdoors
Can gasoline pipe be hooked up through underground foundation walls? - ANS--no, most
effective thru above ground partitions
-have to be covered in opposition to corrosion
Can Organburg pipe be repaired? (P. 416) - ANS-No, there may be no manner to repair this
pipe. Replacement is the most effective choice.
Can plumbing vents terminate below eaves? (P. 429) - ANS-Answer:
No plumbing vents underneath eaves with air flow openings.
Can PVC be used for electric conduit? (P. 417) - ANS-No, PVC can not be used as electrical
conduit. The "PVC" equivalent for electric conduit is referred to as RNC. RNC cannot be used
for water distribution & PVC can't be used for electrical conduit.
Can PVC be used for indoors water distribution pipe? (P. 417) - ANS-No, PVC can not be used
as indoors distribution pipe; However, it could be used as constructing sewer, DWV, & water
service pipe.
,Can vent pipes be used for different purposes (e.G., drainage, and so forth.)? (P. 428) -
ANS-No, a vent system & vent pipe ought to not be used for any other motive than supplying air
to drainage pipes.
Vent pipes & systems ought to:
- no longer be used for every other purpose
- now not be used to assist items (e.G., antennas, flags, and many others.)
Compare the new and old approach of sealing clay sewer pipe joints? (P. 415) - ANS-Older
joints had been sealed with oakum (i.E., tar soaked hemp) & mortar or cement grout.
Modern joints are sealed with compression gaskets & banded couplings.
Copper tubing joints? - ANS--threaded
-braised
-flared (usually annealed tubing most effective) annealed=coiled shape
-crimp fittings that use a special becoming listed to be used with fuel
Defects for sewage ejectors? - ANS--does no longer function well, or starts offevolved and
forestalls, or maintains working after the pit is empty
-pit has been modified
-not vented, or improperly vented
-test valve or full open valve no longer present
-discharge pipe does no longer properly connect with the gravity pipe drainage pipe
-sump pit isn't always sealed
-staining or evidence of overflow exists around pit
-strength failure alarm, if established does now not feature
-pump unusually noisy all through operation
-pump turns on however nothing flows
Defects for sump pumps? - ANS--sump does now not feature, functions and then stops or
operates after empty
-discharge terminates to an improper region
-sump is strangely dirty
-test valve is absent
-discharge pipe is not accepted
-pump moves whilst activated or is not secured
-staining or proof of overflow exists round pit
-electricity failure alarm, if mounted does no longer work
-pump turns on however not anything flows
-pump unusually noisy for the duration of operation
Do call for hot water heaters require habitual maintenance? (P. 406) - ANS-Yes, call for hot
water heater require regular cleansing & protection.
, Note:
- Maintenance is obligatory
- Scale builds up in warmth exchanger
- Build up can block water float
How are "bends" (i.E., becoming to change route of float) identified? (P. 419) - ANS-Answer:
- range of ranges (e.G., 90°, forty five°, and many others.)
- fraction of 360° (e.G., 1/4, half, and many others.)
How are connections to DWV pipes made? (P. 422) - ANS-DWV connections:
- permitted fittings
Note:
- Not w/holes drilled into pipe
How are thermal expansion tanks inspected? (P. 410) - ANS-- Use tire strain gauge to test air
stress
- Normal stress is between 20-forty PSI
- Less than 20 PSI indicates tank needs air
- Water flowing from valve indicates tank failure
How are wye & tee-wye fittings used? - ANS-Answer:
- ANY DIRECTION W/OUT RESTRICTION
How do "electric powered garage tank water warmers" heat water? (P. 404) - ANS-They use
electric powered powered resistance-type heating elements to warmness water in the tank.
How do septic structures paintings? (P. 437) - ANS-1) waste water enters septic tank
2) solids (i.E., dense material) sink & create sludge layer
three) drinks continue to be above strong layer
five) lighter cloth (e..G., grease, fats, and many others.) float & shape scum layer
6) microbes damage down solids & kill dangerous organism
6.1) system breaks down less than 1/2 contaminates
7) Liquid (effluent) drains from tank while full (commonly via a filter out)
8) effluent drains into leach field
9) contaminates are treated in drain discipline
10) Soil does not take away chemical compounds or non biodegradable substances
How do some inspectors take a look at for fundamental issues in a non-public sewage disposal
machine? (P. 436) - ANS-Answer:
- Run water & colour with dye
- Visually check out for troubles in drain field
- Identifies main defect now not minor defect
