 TP
valve / temperature-pressure
valveMechanical 2 in 1 protection against excessive pressure and excessive temperature. TP valve will release water when conditions exceed TP valve rating, causing cold water to enter tank. This reduces both pressure and temperature. TP valve automatically closes when emergency conditions are over. Lift and gently lower TP valve once each year. Residential water heaters are pressure tested to 300 pounds per square inch (PSI) and have a working pressure of 150 PSI. T&P valve will open when the pressure inside the tank exceeds 150 PSI, allowing pressure to vent safely. T&P valve will open if water temperature at top of tank reaches 210°F which is maximum allowable temperature for any water heater. TP valve must be rated for more BTU than tank rating so release of hot water can outpace ability of tank to heat more hot water.... standard TP valve will have a 'steam rating' of 100,000 BTU. If tank is rated more BTU, for example 150,000 BTU as seen on label located on side of unit, then a TP must exceed BTU rating of tank.  Buy: TP

Pressure
gauge on drain valve/ and compare with outdoor spigot/ Reasons why: 1) Problem with low water pressure Use pressure gauge on drain valve, and outdfoor spigot to tank pressure and household pressure. This will indicate if pressure problem is before water heater, at water heater, or after. Water pressure cannot exceed 80 psi (50-60 psi is typical). High pressures can cause TP to leak water. Resource: 5 Steps to determine low hot water pressure  TP valve leaking lot of hot water2) Pressure over 80psi can damage water heater/ pipes/ plumbing/ pumps etc Can also shorten life of plumbing fixtures, and faucet cartridges Can shorten life of water well pump, etc 3) High incoming water pressure can push hot water out of tank quickly, so it appears the heater is running short of Hot Solution for high pressure: install pressure reducing valve, along with expansion tank.

Measure water pressure over time For
people wanting to know about water pressure spikes over time, a
pressure logger can be used.This can be useful if water heater or plumbing fixtures fail frequently due to high water pressure. Always check the obvious first: -Water softener can deplete the anode rod, resulting in rusted tank and early demise of heater. -Stray current corrosion, where electrical items are grounded to water pipes that connect to water heater cause water heater failure.. -Check with neighbors if they have similar plumbing failures due to suspected high water pressure. -Check for closed system, where home has check valve or other restricting valve installed on water line, causing extremely high water pressures when tank heats water. Hot water expands when heated. There is almost no compression with water, so pressure backs up into water lines. Normally pressure from heating water is pushed back into the main line on street, or back into the pressure tank on water well. Check valve or one-way valve such as pressure reducing valve will caused closed system, requiring expansion tank.

 Air
vent/ Eliminate air
build-up in water lineAdd air vent to high point on plumbing At high temperatures, gasses are release from water ... release of dissolved gas can create air pockets and air locks in plumbing systems. The spurts of air or gas when opening a hot water faucet can be attributed to the release of dissolved gasses in the water. Eliminate banging pipes caused by air inside line Frequently found with recirculation systems so pump lasts longer, runs quieter Air in water heater... You can take care of air or gas that is generated in the heater when heater is unused for weeks at a time by adding a vent at the top. This is done by installing a "T" in the hot outlet so that the side port on the "T" is facing sideways.  Now
take your hot water to the house from the side port. At the top port, bush down so you can install a float vent. With hard water, the vent will plug periodically: clean with white vinegar Required with solar installation Buy: Air vent/ Float vent 1/2" to 1/4" brass adapter Use brass adapter... stainless can deteriorate if water is softened Resource: Air vent .pdf |

 "Water hammer is the destructive forces,
pounding
noises and vibration
in a piping system when water flowing through a pipeline is stopped
abruptly. When water hammer occurs, a high intensity pressure wave travels back through the piping system until it reaches a point of some relief. The shock wave will then surge back and forth between the point of relief and the point of stoppage until the destructive energy is dissipated in the piping system. Example: 1/2 ˝ copper pipe with 5GPM flow (7.2ft/sec.) – sudden stop. Pressure rise of approximately 412 psi Example: 3/4˝ copper pipe with 5GPM flow (3.3ft/sec) – sudden stop. Pressure rise of approximately 188 psi Resource Read about water hammer Trigger Start Torch |

regularly Read more about anode odor problem at pro water heater forum Install ball valve on Hot side so you can pour in peroxide Hot side will allow peroxide to enter top of tank. (cold side will put peroxide at bottom) Applies to gas and electric heaters. Turn off power to water heater: Let tank cool so hot does not explode out ball valve Shut off cold water to tank. Open bathtub hot side to release pressure. Leave bathtub valve open until finished. This will tell you when tank has refilled and ready to apply power. Drain 2 gallons from tank Add 2 pints harmless Hydrogen peroxide to water heater. Let stand for 2 hours. H2O2 is easy to flush out, and generally harmless to people. Can be used as mouthwash, read label on hydrogen peroxide bottle. Do not use clorox. CLOROX is NOT used for this purpose since it cannot be easily flushed out, and bleach odor can last weeks or longer coming out each tap for extended period of time. Then drain tank to flush hydrogen peroxide. Refill completely until water is coming out of bathtub drain, then turn on water heater. Applies to gas and electric heaters.
