Error P1 is not enough water flow. Clean water filter located on cold water inlet at top of cold pipe when cold enters unit Test single handle faucets for crossover Check if faucet can fill 1 gallon can in 30 seconds.
If you are talking about the water valve on the cold water inlet it should have a nut under the lever if it is a quarter turn ball valve.If so you can remove the nut that hold the lever on and carefully tighten the nut by turning it clockwise.This should stop it leaking if it is coming from around the stem. If it is a globe type valve there should be a packing nut that goes around the stem under the handle. Tighten this nut carefully to get leak to stop.
If it is leaking anywhere else then you will need to have the valve replaced.They are available at almost any hardware store.Thank you.
Could be your thermostat but it might be your inlet dip tube. Your water heater has a plastic pipe that carries the cold water to the bottom of the tank. When you open your tap, it takes the hot water from the top of the tank, the cold goes to the bottem and gets heated. If this tube breaks, or comes loose, it will short circuit the cycle. The tank is hot but as soon as you start using water, cold water comes in at the top and mixes with your hot water, giving you just warm water. If you have room above your tank, you can remove the union on the cold side , screw out the pipe nipple, and look inside and see if there is a tube. If not you can buy one from home depot or lowes for just a few dollars. Also a water heater should be partially drained annually to remove any solids from the bottom, which will allow better heat transfer.If you find bits of plastic when you do, then you know where your dip tube went. Also if you've had a hot water faucet stop up and it looked like plastic there it is.
That is normal, the heat just rises from the hot water, the pipe on the right should be cold and if you were to run hot water anywhere in the house it will immediately cool of the cold inlet pipe and you can feel it
If water is leaking from a pipe. then replace or repair the pipe or fitting. If the leak is coming from the unit itself, then replace the unit. Hope this helps.
Sounds like bottom element may be bad but
usually reads open circuit if bad.
Also tan k would run about 8 gallons hot water then go cold.
lots of warm water usually means bad dip tube.
Check if tank is hot at bottom element when not used for a while.
If bottom element is still cold then bad element.
If bottom element is hot - (all water in tank is hot then you have a bad "dip tube"
This is allowing incoming cold water to mix with outgoing hot water.
The dip tube is usually
A part of the cold water nipple or
B located under the cold water inlet nipple.
Shut the water off to it (should have a valve very near it on the cold side) and kill the breaker at the electrical panel. This needs replacing if it's the pipes I am thinking (the two 3/4 inch nipples coming directly from the top?).
