Need a plumber to replace a sink siphon quickly

I’m a homeowner in Ireland looking for a professional to replace the siphon under my kitchen sink. The current siphon leaks occasionally and I’d like a reliable, water-tight fix. Please include removal of the old siphon, installation of a compatible new siphon, and testing to ensure no leaks. I’d prefer a standard UPVC/metal siphon with a secure seal and no requirement for major alterations. If you have a preferred brand or type, I’m open to recommendations. Access is straightforward, and I can be flexible with the appointment if you need to bring specific parts. Please provide an upfront quote and confirm that the work will be guaranteed.
