Moved house a few weeks ago and the sale of our old property is due to complete next monday. I went back to the old house this week for one last clean and tidy before we have to hand in the keys and noticed an issue with the plumbing and hot water. Called a plumber who managed to come the same day and advised what the issue is. Said he would order the relevant part and be back. I stressed the time time sensitivity of it.
I've been chasing him daily and he still hasn't been. Sometimes it takes days for him to reply and then he will just say he's still waiting.
If this doesn't get sorted before Monday what do I do? I can either come clean about the issue and offer to pay but the buyer will have to provide access for the plumber if/when he finally comes. Or I can keep quiet. It's not a huge or particularly obvious issue, the hot water just isn't reaching the temperature that it should. If I hadn't come back to the house to clean I wouldn't have even known because it wasn't like this when we were living here.
It doesn't feel right to leave the house with a fault though. I'm genuinely asking what my options are in this situation? Do I tell my estate argent when I hand the keys in?
