Single Lever Mixer Tap Leaking

Martyboy60 · 2026-01-07T11:59:03+0000

Hi.
My single lever mixer tap has been leaking for a while. Water trickling from below lever when off. I've tried to remove the top bit/lever and can't do so. The blue/red cap appears to not be removable and I'm scared to try to twist the base of the tap to see if I can access washer/cartridge. The pictures below show the branding on the tap (a triangle and then TP, 0135M, U/A. Is it possible for me to remove the lever and access the washer mechanism or do you think a tap replacement is required? It is pretty old.
Thanks for any help.
Lou

The blue/red cap, probably hides a grub screw, which hold the handle in place. Pick the cap out, with a sharp blade, under the lip.

I don't think it does. It appears to be glued on or in. Any other thoughts anyone?

Fixing behind the blue/ red cap, but just get a new tap.
