I actually tried to free them up with vinegar and baking soda, several times, and this last time made them so much worse. The plunger has been in the kitchen for the last six weeks, doing stand-by duty for the sinks.
If I owned this place, or was buying it, I might be tempted to follow your advice. However, I don’t, so I won’t. These places were built over 40 years ago, and the tenants have ranged from extremely careful to slovenly, with no respect for other people’s property.
There isn’t much I can do except call and protest, then write a letter telling them that I pay my rent in good faith and if I am forced to “go native” for a few days, my rent should be adjusted accordingly.
However, the standing water is looking ugly, and for some reason, since developing CFIDS, I have become squeamish about certain things. Go figger.
I will call again this morning as soon as the maintenance lines are open, and tell them it is becoming a health hazard. I do NOT know what is in the drains, but whatever it is, it can’t be pristine drinking water.
(I’m waiting for the water to begin to froth and reek, like the Bog of Incredible Stench.)
When the Helping Hands ask if you want the water to go up or down, say down...
You have a lot more patience than I. I would have resorted to explosives way before now.
