Hi Steveb
I have done! I've passed all my exams up to yet and revisied properly for each one. The only thing is that other students im my class are falling behind and i am the only one who has passed all my exams so far, first time. And for my tutors its quite hard for them to sit with only 1 me alone to cover the modual. I dont want to leave it too late too - n ur right i should revise

Smartscren emailed my tutor and said that the college will have to register again, I don't know why though! If any body could get on to smart screen 6129 basic plumbing studies level 2 there are two exam papers on central heating with the answers on them, could some body email them to me [email protected]
thanks

the benefit of using smart screen is that it is just like a mock practice on line of taking the gola exams, that is the point.
The answers to the questions that you seem so much in need of ( from this thread and others ) are in your jtl book and what you cover at college. when you sit the actual tests there are always going to be questions that you did not cover, that you have not memorised. 2 answers out of 4 are usually silly anyway. researching the complete subject rather than being given all the answers is what you need to do.

4When fully draining down a heating system
a)all the air vents should be closed
b)the open vent pipe should be capped
c) the air vents should be opened
d)the radiator valves should be closed.
5 Tosatisfy regulations, the controls required for a fully pumped heating system(hot water priority) using a zone valve arrangement, consists of
a)two number 2 position diverter valves, time clock, cylinder thermostat, roomthermostat
b) 3port valve, programmer, room thermostat, cylinder thermostat, TRVs
c) 2 port valve, time clock, roomthermostat, cylinder thermostat, TRVs
d) 2port valve, room thermostat, cylinder thermostat.
6The cold water supply to a fully pumped open vented central heating systemshould beisolated at the
a)stop valve to the incoming cold water supply pipework
b)fullway valve on the cold feed pipework from the F & E cistern
c)service valve to the float operated valve to the CWS cistern
d) service valve to the float operated valveto the F & E cistern.
7 Onan open vented fully pumped system, positioning the pump between the cold feedand vent would
a)mean installing a three port motorised valve on the primary flow
b)increase the efficiency of the central heating system
c) result in water pumping over the ventto the F & E cistern
d)result in water pumping over the vent to the CWS cistern.
Inan indirect system of heating and hot water, which includes a cold waterstorage cistern and a feed and expansion cistern
a)the water level in the feed and expansion cistern should be below that of thecold water storage cistern
b)the two cisterns bases should be at equal level
c)the water level in the feed and expansion cistern should be above that of thecold waterstorage cistern
d) the water levels in the two cisternsshould be equal.
2The connection of an open vent pipe and a cold feed pipe, can be made to afully pumped
systemusing
a)an automatic air vent
b)an injector tee
c) an air separator
d) adiverter valve.
3Which of the following is regarded as best practice when branching a large newradiator circuit into an existing heating circuit in cold weather?
a)Drain the system down as the first action.
b)Branch into the pipework before fitting the radiators.
c) Install the new radiators and pipework runsbefore branching in.
d)Install the radiators, branch into the pipework and install the new pipework.

hi again
The most efficient way of draining a single radiator when removing it from the first floor of a dwelling is to:
1 Isolate the valve and drain down the radiator or
drain down the system as far as the first floor
