I've been renting this home for more than a year and there have been a lot of plumbing issues - mostly leaks, but the water in the kitchen has always heated fine. There is a leak under the sink as well, though I can't see it dripping, I can just see that the cabinet floor is wet. The hot water is working in both of our bathrooms, so I figured it wasn't the hot water heater. What could cause something like this? My landlord drags her feet with getting these things fixed, and when she does send a plumber out it's always one of her friends and he doesn't actually fix anything. Maybe if I know what needs to be done I can hire my own person and deduct it from rent.
