Hi,
Going to change a DHW heat exchanger and three way valve actuator (cartridge) for a customer on this boiler shortly. Is it safe to close the isolating valves (flow,return and cold water) on this boiler or will they leak? Also is DHW replacement staight forward on this model or any pitfalls?
don't normally work on Saunier Duval's.
Kind Regards
