I live in a 2 flat which is about 50 years old. My landlord changed a water heater and afterwards the water flow to the kitchen sink is practically non-existent. He changed out the water faucet blaming accumulated rust debris for clogging the pipes. Despite this, the pressure has not improved. Oddly, the flow to the bathtub is now 2 fold. Now I can take great showers but can’t fill a glass of water without a 10 minute wait. What’s the problem? I fear I may be subjected to water poisoning of some type if I am drinking water from “clogged” pipes. I would appreciate any suggestions since the landlord hasn’t returned in 2 weeks to address the situation! I think he’s avoiding me and a plumbing bill! thanks, tj
