Hot bath tap making a slight whistling sound when running

[awm]

Hot bath tap making a slight whistling sound when running.

The sound is so slight I couldn't record it for you, but it's a sound it wasn't making before.

It only happens with that tap.

I wonder if it's something to do with the pipes. I just wondered if there's anything I should do?

It started about 6 weeks ago.

Any help appreciated.

I've attached a photo of the tap if that helps.

Thanks.

Replace the tap washer

Okay thanks, just the hot one, or both hot and cold?

These should do it right?

No they are 1/2 inch
You’re tats look like older ones go to b and a and by 3/4 inch tap washers about a pound

Those are ceramic cartridges. You might just need a washer. Do you need to turn the tap multiple times? If yes, you just need a washer. The ceramic ones are often a quarter turn to make the water come out.

Okay thanks. Turns out I already have one (it had a blue ring on it, so I just changed it to the red one). I just replaced the whole hot tap following the instructions on this video.

The tap works better, but now the whistling sound is actually louder.

I've noticed the whistling sound completely goes when I turn on the hot tap on my bathroom sink at the same time as the bath tap.

Here is a video to demonstrate (you can hear the sound now, it's much louder with the new tap)...

Any ideas?

Thanks for your help.
