Welcome to the Bunnings Workshop community @philplant. It's terrific to have you join us, and many thanks for the question about your cold water tap.

That sounds like a bit of an unusual one. Could you please share a photo of the tap so our members can better understand what you're working with? Let me know if you need a hand uploading images.

Have you tried any troubleshooting as yet? It sounds like there is either a significant issue with the tap, or it might just require servicing. Once we have a better idea of the style of tap, we can advise on what parts might need replacing. If it's a valve-style tap then installing a tap valve repair kit would be an idea or if it's a mixer tap a mixer tap repair kit.

Please let me know if you have any questions.
