Hi, I'm looking for someone experienced to unblock my kitchen sink. The water is draining very slowly and sometimes not at all. I’ve tried basic methods like using a plunger and drain cleaner, but nothing has worked. Ideally, I need someone who can come with their own tools and fix the problem quickly. It’s a small kitchen sink in a rented apartment in Dublin. Please let me know if you have experience with this kind of job. Thanks!
