I'm not sure what you want here - do you want us to complete a practice paper for you?

It's all basic stuff - just refer to your notes and books. The way to learn is by attempting these questions yourself with reference to what you've learned on your course.
 
Number 1 is a)

Time for me coffee break now. I'm exhausted ...
 
2 b)
3 c)
4 c)
5 a)

Hmmm - not too tricky - but how do you know my answers are correct - especially given my nickname?
 
how can you learn when you ask us to do your work for you?
 
The answers will all be in your text book
 
If these are examples of level 2 questions, what are level 1?
The mind boggles.
 
I'm trying, any help with these too :) thanks

I agree with the others, if this is the extent of the stuff you do not know, you need to get yourself a book and revise, for us to tell you would,

1. may be wrong as even well experienced plumbers forget some things occassionally
2. take up way too much time
3. not teach you but give you the answers.

Get a book, £30 for a book is cheap compared to tools, tax, advertising, diesel, i.e. just go and get a book

Also seems like you are on cold water section, if memory serves me correct you will need a different book, cold water supply and fittings is a good one, even if you get it from library
 
Have you actually learned anything on your course?

This is basic, basic stuff - it needs to be in your head and second nature. Honestly, you need to answer these yourself and then seek advice (preferably from your tutors) if you can't answer.

Many thanks for the appreciation/acknowledgement for my earlier answers.

Not sure why I should bother with any more.

PS - all the answers to No12 are wrong!

Level 1 is introduction to construction, so very basic stuff. basically for 16-18 year olds to understand the very basics of plumbing, electrics, brickies, carpentry i.e.
 
Many thanks for the appreciation/acknowledgement for my earlier answers.

Not sure why I should bother with any more.

PS - all the answers to No12 are wrong!

Not sure but isnt 12 both pipes should b e the same height from bottom. like i said not sure.
 
Don't want to upset the fun. But has anyone noticed the op has now left us?
 
just been through the questions, some haven't got pictures needed, the rest don't say how many answers. makes life a lot easier when you know how many answers, but apart from that, I am shocked at how many I was unsure about. may need to research these, there's the obvious ones, like pipe sizing, who do you inform when turning the water off, ummmm, errr i think it is the water board, lol

but things like what would you use an injector tee for? Ummm I wouldn't.
what would you use anti gravity valve for, gravity hot water. but that isnt an answer.
 
I've been helping him on another thread!! He's obvioulsy hopping around the forum, gleaning some info here and there!! :)
 
All of the answers are in the book(s) he should have to hand.
The trick is finding them but a. Useful exercise for later courses when sitting in an assessment centre, no help and just a. Computer counting down for company...
 
Hello could somebody see whether I've got any wronge. thanks

1A boiler requiring a greater waterflow rate through its heat exchanger than the heating and hot water circuitsrequire, should be fitted with

a) a pressure limiting valve
b) a flow restrictor
c) a pressure reducing valve
d)an automatic bypass valve.

2 To satisfy regulations, the controlsrequired for a fully pumped heating system (hot water
priority) using a zone valvearrangement, consists of

a) two number 2 position divertervalves, time clock, cylinder thermostat, room thermostat
b)3 port valve, programmer, room thermostat, cylinder thermostat, TRVs
c) 2 port valve, time clock, roomthermostat, cylinder thermostat, TRVs
d) 2 port valve, room thermostat,cylinder thermostat.

3 Which one of the following gasboilers overcomes the need for a cold water storage cistern, feed and expansioncistern and hot water storage vessel?

a) Back-boiler.
b) Condensing.
c)Combination.
d) Room-heater

4 If TRVs or zone valves on a systemclose, the purpose of the automatic by-pass valve is to make sure that

a) water can flow through the cylinder
b) air cannot enter the heating system
c) water cannot pump over the vent
d)water can flow through the boiler.

5 The revised Building RegulationsPart L1 require that when fitting a new oil fired heating system, the systemshould be

a) gravity hot water and pumpedheating
b)fully pumped with a boiler interlock
c) heated by combination boiler only
d) installed by CORGI registeredplumbers.

6 On a fully pumped system using a 3port mid-position valve, neither the heating nor hot water can be runindependently. The most likely cause is that the
a) cylinder thermostat is faulty
b) room thermostat is faulty
c)3 port valve is defective
d) pump is running constantly

7In an indirect system of heating andhot water, which includes a cold water storage cistern and a feed and expansioncistern

a)the water level in the feed and expansion cistern should be below that of thecold waterstorage cistern
b) the two cisterns bases should be atequal level
c) the water level in the feed andexpansion cistern should be above that of the cold water storage cistern
d) the water levels in the twocisterns should be equal.

8 Before filling a central heatingsystem for the first time, it is advisable to

a) remove all radiators and replaceeach with a piece of temporary piping
b) turn the pump on to assist with thefilling process
c) ensure that all radiator valves areleft in the closed position
d)remove the pump (accelerator) and replace with a piece of temporary piping.

22 Which of the following is regardedas best practice when branching a large new radiator circuit into an existingheating circuit in cold weather?

a)Drain the system down as the first action.
b) Branch into the pipework beforefitting the radiators.
c) Install the new radiators andpipework runs before branching in.
d) Install the radiators, branch intothe pipework and install the new pipework.
 
I'd say c for 22 because you're keeping the existing heating on for longer before having to break into it.

Otherwise you seem to be doing well.
 
Read the books! You should be embarrassed asking these questions in all honesty!

Do you want me to send you the page numbers?
 
Read the books the answers are in there your doing ok though for a total newbie with no experience the wording can be daunting.....

But nobody and I mean no one should be embarrassed about asking questions on this forum - that's why it's here :)
 
It's not asking questions though it's asking for answers. If you'd have highlighted the answers which you thought were correct we can see where you might be going wrong.
 
Hello everybody

I have completed mt C&G 6129 Basic Plumbing Studies Level 2. I only failed 1 exam!!! I really want to take my BPEC Water Regulation 1999 exam. But concered that I might fail it because I've not started 6129 Level 3 plumbing, yet! Also, could somebody send me some exam questions [email protected] Cheers
 
mohammed, water regs is really easy to do it is all open book. you are given the water regs to read through before the exam. you are then given a talk about them. the exam itself gives you the question then goes on to tell you where you will find the answer in the book (which is more like a folder actually).
 
PS - all the answers to No12 are wrong!


(d) Cold distribution pipe must be lower than the cylinder cold feed pipe.

I wouldn't have been able to answer this a few days ago but I had a flick through the trelour book after answering another thread on here yesterday or the day before and learned (re-learned) a thing or two.
The answer is 'd' because if a mixer shower is present you want the hot to run out before the cold to prevent scalding.
