Water pressure too low, too high or weak flow.

A trained tech can take gauge readings, and a licensed plumber should install regulators, boosters or new piping.

Customers put it like this

  • Low pressure all over the house
  • The upstairs shower is weak
  • One faucet barely runs
  • Pressure dropped after our remodel
Check it step by stepPrepare this job in ForeBot

Stop first if

  • Someone has capped or plugged the relief valve or relief pipe on a working heaterTreat it as an explosion risk. Keep people clear and call a licensed plumber now. Turn the heater off only if it can be done without risk.
  • A well pump or booster needs live electrical readingsLeave those to a qualified technician. Pulling a well pump goes to a well contractor.

Check it step by step

Answer what you can see or measure. Each answer sets causes aside, and the check offers the one cheap reading that best separates the rest. Nothing is saved, and no account is needed.

Ask on the call

Homeowner? These are the questions a good technician will ask you. Having the answers ready makes the first visit count.

  1. Is it every fixture, one floor, or one fixture?
  2. Is it hot water, cold water or both?
  3. Did it start after a remodel, a new filter or softener, or street work?
  4. Are you on city water or a private well?
  5. Does it drop when one appliance runs?
  6. Is anything running now, like irrigation or a toilet?

Bring

  • Pressure gauge for a hose bibb
  • Second gauge for readings across a filter
  • Pressure gauge that can record over a day
  • Tape measure for outlet height
  • Flashlight

Check on site

  1. Sketch the path: meter, backflow device, regulator, softener, filter, heater and risers. Trace where the hose bibb tees off.
  2. With nothing flowing, read static pressure near the service and at an indoor outlet past any regulator.
  3. Compare with the local code limit, not a number from memory. Note any regulator setting.
  4. Read static at the complaint outlet and compare with what its height predicts.
  5. Open other fixtures on that branch and take a second reading. A drop only under flow may point toward a restriction.
  6. At one fixture, run hot and then cold and compare. Check the aerator and confirm each valve on the path is fully open.

Keep on the record

5
  • Static and flowing pressure readings, with place and time
  • Sketch of devices between the meter and the outlet
  • How far the problem outlet sits above the service
  • Zone and normal range as told by the water utility
  • Pipe material and the last filter change date
