Water Problems

I had low pressure in my 5er and removed the pressure regulator. The pressure increased and after about 4 hours I have only cold water in the kitchen faucet. I have lost all hot water and all water to the bathroom. I know I messed something up, but don't know where to begin. Any help would be welcome.

  • 1. Do NOT remove the Water heater drain plug, not neccesary, just open the Pop Off valve and see if water flows
    2. Do you have a Whole House filter???? If so, it may be clogged. remove the element and reinstall without the element and see if you have water. Doug
  • It could be the supply is frozen to the hot also. Like old Biscuit said, get some heat in there and get things moving before anything breaks.

    No hot......you stated you don't have hot in kitchen also so that is probably due to the check valve on water heater hot outlet.
    Remove WH drain plug and check that you have water in it.

    The lack of cold water in bathroom could be a frozen cold water supply line going to bathroom.
    Check for cold water line running next to outside wall......open any cabinets/accesses and get some heat into that area.

    There are no 'system' shutoff valves other than at sinks.
    If you have water supply then all cold water should flow unless line is frozen
  • I have no water to anything in the bathroom, hot or cold.
  • +1 on the water heater check valve. If you can do it youself the replacement will cost you about $10. Have a look at it before you go to get the replacement as the thread setups can be different. It should be a male thread into the tank but the outside end can be either male or female thread depending on what you currently have. Any RV place should have them.
  • If you are any where near us -9 below zero it might be frozen. Make sure the by pass valve is shut and water heater valves are open. Good luck
  • Having cold water at faucet but no hot water is typically a stuck/broken check valve in Water Heater Hot outlet----they are internal on fitting at tank.

    Loss of ALL water to bathroom.......
    Does that mean bathroom sink, shower and toilet???
    Don't know your bathroom set up
    Having NO water (hot or cold) at a faucet is typically a plugged up aerator on end of faucet.
