Hello, It's that time of year again when everyones put their heating on and you watch the Operating pressure struggle to get to where you want it..
I'm after a bit of advise regarding what people have left on safely with regards to operating pressure.. I have just fitted a 34cdi.. I didn't check the op pressure of the old Worcester 34CDi I took out (1990's job) but having come to commission the new install tonight had only 12mb standing and didnt even bother with operating... called the gas board out and he did the usual cv..bridge the meter, but nothing worked... checking next door they were rocking along at 15.2 working (so he said) and similar up and down the road.... so there is a problem in the road..and he clearly looked worried he was going to have to start shutting people off...dont envy that job tbh... point is, he seemed to think if he could get me to 15 like the rest it's all good.... it's not, as mentioned in TECHNICAL BULLETIN TB 0040 a (2010/09) - 15mb is for only a short time and shouldn't be left like that...
I cant commission a 34cdi on that even if he does get me 15mb.. 14mb on 34cdi isn't accetable is it..
So whats the score? I dont do loads of this sort of work, and rarely have a problem like this which isn't fixed by CV swap or meter/ blockage.. the pressures are usually good in this area...
any advice appreciated....
