Brand new CH water pump so noisy

[ukrobj]

Probably as far as we can go with advice online, worth phoning around to get someone in to check it. I don't believe it needs a powerflush as this all started with the new pump.

I think you are right, I am just trying to be a better informed purchaser of plumbing services before I call in another, what will be the 5th plumber in just over a year trying to sort out our CH, each one saying the last lot didn't know what they were doing.

Thanks for your input.

One place to check is the cold feed and vent connections for blockages. View media item 39013You may have a setup similar to this.

Probably not the problem but if the pump has been fitted with testion in the pipes that can help transmit noise.

You could loosen one of the nuts on the pipe side of the pump connector until the pump can be twisted a fraction and rotate the pipe compared with the connector.

Retighten without letting the pump rotate relative to the pipe. That might need two wrenches.
