If the low water pressure seems restricted to a single faucet or showerhead, the problem isn’t with your pipes or water supply, but with the fixture itself. If it’s a sink, the most common causes are a clogged aerator or clogged cartridge. These cloudy spots block the flow of water and decrease water pressure.

  1. Your water temperature isn’t right. If a TMV valve stops working correctly, then you may notice that your hot water suddenly starts to run hotter than it should.
  2. Your water doesn’t flow normally. Sometimes, the first sign of a TMV problem is a change in the way your water comes out of a tap.
  3. You have leaks or drips.
