dry them out using hair dryer,paper towels etc

Could be by-pass problem...no? You say the problems started when a rad was turned on, this tells me water has took the easiest circuit once this rad was opened, therefore taking the flow from the other rads.....check the pipework & the by-pass,could be it needs a cple turns in.

Chances are its the PCB again,could be the thermistor also. If theres no lockout & you can rule out pump,actuators,stats then its pointing towards PCB again,quite a problem on these models. Ive just installed a new one on my 40l & its the second one in 3yrs,bad design methinks.

Ive been thinking lovemuff, your right & I think your always right.....Ive just phoned my boss & told him to forget putting me thru this stupid course, what was I thinking, P45 now in the post......phase rotation is not all its cracked up to be, too much for me i'm afraid.......I just dont get...

Think the first 4 posts tells all lovehandles,what would be the point now.... why dont you check them out if your unsure :roll:

Eric, i agree with everything you said. Thing is there will be a shed load of gas engineers in my situation as these smart meters are kicking of big time, the utility company's need dual fuel engineers so the cheapest way for these companys to do it is to put gas engineers thru the leccy course...

Christ, I give up. Number 1. I have a Job,i'm merely gaining a qualification to work on the leccy side. 2. We pull the fuse at the service before we start any work, obviously checking polarity first. There is NO working live! 3. I will not be going out myself but shadowing a sparky for a month...

Youve got this wrong, I do understand the workings......its the simplifying it down on paper so I can explain it, there is nothing wrong with trying to figure this out so im better prepared surely?? The phase rotation was lectured during the course but theres not much of it in the course books...

We have done, got the interview this week though so thought I get a heads up using the net first for more info, we have been given books but I explained to the tutor there is no mention of phase rotation in them hence why I'm on here, I appreciate this is simple stuff for the leccys out there...

Take a pill holm, its the simplified wording im looking for not the overall understanding, ive already sat 5 exams & 3 practicals to get to this point...i'm a gas engineer who's being put thru an intense course which allows me to work on electric meters, cheers for the concern though :roll:

Cheers Taylor, Ive googled it but I was looking for a simple explanation from an experienced sparky,I have an interview for a permit to work next week & one of the questions is on phase rotation, I'm just looking to memorize a simple answer, any help would be appreciated.

Hi, can anyone tell me how to explain Phase Rotation.....what it means & how it works??

And the winner of the most self righteous to55er of the year goes to.....1CANHELP

ICANHELP....what an ironic username considering that was utter drivel you just posted!

Yes, new meter....new guvnor, new pipework as long as its 1-2 meters from original position.

No, move the meter/pipework within 1-2 meter....usually involves cutting outlet pipework 1-2met,extending/replace with new pipework fittings etc,replacing (with extended flex) guvnor & meter,re-test etc

Why pay a RGI when the supplier does it free? Unless they have a friend who does "Mates Rates" :roll:

I'm a RGI who is also qualified to move gas meters & do this on a regular basis, these jobs are done free (by supplier) as long as they are within 1-2 meters....the problems arise when the customer wants the service pipe moved to outside or wants an external meterbox fitted,these jobs are priced...

Phone your supplier & request a meter move/reposition, they will send an engineer out who will reposition it within 1-2 meters (only) of original position, they will not move the service pipe though...they will replace the guvnor & meter while they undertake this work aswell.
