That type of thing is urgent - they should be sending out a plumber asap, and am electrician for the faulty switch. We had an issue with our rental where the toilet pipe became blocked and the toilet was essentially unusable - pm sent a plumber immediately and told me as soon as she could get on to me. I was fine with it as we can't leave the tenants with no toilet!

Since then the rest of the plumbing has failed and it's being redone. But the tenants couldn't stay during the work as they'd have no access to a bathroom or toilet and some of the floor is being removed. So they didn't have to pay rent while they were looking for a new place, and once they moved out work started.

I'd be putting in a complaint to the re company, you can't live in a dangerous house with no working plumbing.
