Hi David, First of all, you posted the question in the wrong category. You should have posted it in the plumbers category. On some of the mixer taps, you can replace the cartridges, but the best thing to do, is to get a plumber to do it for you. You can also post your job under the plumbers category and you might get some phone calls from plumbers in your area. Hope this helps,
