I live in a building almost as old as me. Like me, parts of my unit are wearing out and malfunctioning. That was the story with the tub faucet. The original equipment was about 60 years old and the hot water went from a drip to a constant stream, with the heat creating stains and mold.
I asked the office who did a lot of work at our complex and the said Pono at MG Plumbing. It didn't take too long to get an appointment. The shower head was a mess too, so I asked Pono about a new shower head with a hose, which would make it easier for me. He said I could buy one, or he would. I asked him to get one for me. I have a mobility disability, so it's hard for me to shop in person. I looked at many options online, but ultimately I figured he would know best how to proceed.
He was on time and selected a moderately priced Kohler shower head. It attaches via a magnet, making it easier for me to detach and reattach. That's helpful for me not just because of the disability but also because I'm so short.
He finished the work quickly and even put up the new plastic liner and just-washed fabric curtain. Just taking down the nasty dirty moldy plastic liner and the fabric curtain which desperately needing washing was quite a struggle for me, so I was very grateful when he did the work for me when I asked.
He also prepared me for what would eventually come after this, once this fix wore out. (Let's just say I'd better start saving lots of money.)
Once the hot water stream was fixed, I was able to scrub the tub and bleach the mold away in bits and pieces over a couple of weeks, as my body allowed. Now the tub looks pretty darned good. Hopefully I look that good, too, as we both continue to age.
