Hi guys,
I had a Worcester bosch engineer out yesterday to look at my boiler, its been giving me some gip.
Turns out I need to replace CH pump, however during the work guy did a gas pressure test and said it was too low. Now my boiler cover plan from Worcester bosch is invalidated until I get the gas pressure sorted.
It was 13.3 at the boiler - and then 13.1 when the gas hob was going full blast. I have no other gas appliances. I need to have 16.5 at the boiler.
Then I got natrional grid out to test meter, as they changed it abut 6 months ago and I recalled the guy saying pressure was a bit on the low side when he changed it. The pressure at the meter was 21. He adjusted it a bit and said he cranked it up to 22 last night.
I just looked at the pipe work from the mains inlet, to the boiler. There is 0.5 metre 22mm copper coming out meter, then 0.5m 1.25" iron pipe, then 3m 1" iron, then the rest is 12 metres of 22mm copper all the way to boiler. 16 metres pipe work in all.
I counted the elbows, I got 22 elbows between the meter and the boiler. The engineer said yesterday you lose x amount of pressuure per elbow. Cant rememebr the amount, maybe he said up to 0.5 per elbow.
Anyonen got any views? I am losing a lot of pressure somwhere - got no leaks! With that amount of elbows, does it sound about normal to lose that amount of pressure? (22 down to 13.3)
Obv this aint the kind of thing I can sort myself, it's gas, would just like to hear some opinions so I can have some confidence in whats require to sort it out.
Thanks very much guys.
