Low cold water pressure after boiler repair?

Postby Allan1872 » Wed Oct 27, 2021 1:34 pm

I'm new to this forum, so please bear with me. I recently had my boiler repaired. There was a blockage that stopped it from reaching the ignition stage. I assume it was some sort of sequencing. The water blockage was repaired and my boiler is fine now. The problem I have encountered immediately afterwards is when I'm trying to use my jetwash, the output pressure is lower, I confirmed with another jetwash. I can't be 100%, but I think the cold water supply pressure is lower and I know the jetwash requires a minimum inlet pressure. Also, when I was using the jetwash, and I pressed the trigger, there was an initial thud from what I can only assume is the cold water piping inside the house.
