Oil boiler pump

[Rollerball]

The pump in my oil fired boiler was intermittently failing to start about a year ago and was replaced with a brand new one.

Only today I've noticed that the pump seems 'noisier' than usual, namely the noise it makes is a slightly higher pitched whine.

Is this anything to be concerned about? Naturally I don't want it failing over Christmas/New Year but equally I don't want to pay for an engineer to come out only to find that it's 'normal', or that we 'need to keep an eye on it', etc.

What do you good people think?


Thanks

EDIT: Decided to call the engineer out as the noise is definitely getting a bit louder, even since I originally posted the above message. The new pump was only installed 10 months ago so I would hope that if it's faulty it's covered under some kind of warranty!

the grub screws holding pump onto motor may have worked loose, i dont do them up too tight. Or the motor if fekked. Not unusual after a pump change.

Thanks, hope it's something as simple as loose screws.

Why do motors fail after pump changes though?

Usually because the pump leaks kero into the motor bearing !!

I'd check everything was clean first.

Hopefully the engineer will do that - he's a good bloke and I trust him to do a good job (hasn't failed me yet). I daren't fiddle with it myself in case I make things worse.

its normaly the motor not the pump that whines
does the noise continue or only first few mins on start up?

The noise is present all the time, from start up to shut down.
