Hi to all,
I'm a gas engineer having a bit of a nightmare on a job, we have installed a vaillant Eco tec 837 37kw. We are getting 12mb working pressure at boiler and 19mb at meter. original pipe running from meter was in 22mm so I thought pipe sizing issues, we have now installed a 28mm run from meter to a 22mm pipe which is around a meter long that connect to boiler. Still getting the same working pressure 12mb , I have tried everything then I thought it was boilers gas valve. Vallient engineer turn up and he said there was nothing wrong but still changed the valve and we still have the same working pressure. I'll really like to hear any advice would really appreciate thank you
