I'm a long time landlord and have seen a lot. In fact, I've seen something similar to this before but thought I'd post here for collective input.
One of my tenants has been something of a yo-yo. I think one is likely a bit bi-polar and that is leading to this current issue. They complained that there was a problem with the tub faucet and the problem was verified. I bought a new faucet set and 2 days after they notified me, the plumber was out there to install a new faucet. As the plumber neared the end of the job, he realized the tile+mud was deeper than usual and the faucet stems were not long enough. He was able to connect the cold water faucet but not the diverter or the hot water knob. Stem extensions are available but specific to each brand and sometimes different models within the same brand have different fittings.
The plumber and I both spent the next day calling and visiting vendors but no one had the extension we needed in stock. I had to special order one. It may arrive today (Saturday) but now it's looking like it may arrive too late to be installed today. It may be Monday before the tenant has hot water in the shower. The husband was updated Friday and said he understood and was happy I had the plumber out there 2 days with a new faucet - no big deal. A couple of hours later, the wife called, was in a venting mood and was not the least bit understanding. She even mentioned leaving at the end of the lease, but tried to backtrack when I agreed that might be a good idea.
I'll add this is a tenant I've bent over backwards to be understanding when they had issues during the past year of C19, and with a couple of other things. They could have been in a bad situation with a different landlord, but things worked out in the end, so far. Their lease is up in June and I'm thinking of not renewing it, but I don't want to overreact to a tenant in the middle of an episode.
Would would you do?
