Hi. I'm looking for a plumber who doesn't charge a huge call out fee if that is possible. I have what I think is a very small job - on my bath, the fixture you turn to get the water to switch from bath to shower is stuck. I think it has been turned too far and now it won't work. I think it will be really straightforward to fix for someone who knows about plumbing, but I know lots of plumbers have like a £100 call out charge which seems extreme for such a small job. Is there anyone who can help me at a deliciously low price? Bonus points if you can come on a Saturday
