5:20 I am a bit concerned that the expansion relief valve starts to open at 391 KPA and the pressure control valve supplies water at 400 KPA . Does this not result in a constant flow of water being wasted when the supply pressure is 400 KPa or above ?
very nice video .as an IE i see geysers regularly ,its just a pity most of the installs are not up to code .
Best teacher ever 🙏God bless you sir
